`
`Exposure to Radio Frequency Signals- Your wireless hand-held
`portable telephone is a low power radio transmitter and receiver. When it
`is ON, it receives and also sends out radio frequency (RF) signals.
`In August, 1996, the Federal Communications Commission (FCC)
`adopted RF exposure guidelines with safety levels for hand-held wireless
`phones. Those guidelines are consistent with the safety standards previ-
`ously set by both U.S. and international standards bodies: ANSI C95.1
`(1992)*, NCRP Report 89 (1986)*, ICNIRP (1996)*
`Those standards were based on comprehensive and periodic evalua-
`tions for the relevant scientific literature. For example, over 120 scientists,
`engineers, and physicians from universities, government health agencies,
`and industry reviewed the available body of research to develop the ANSI
`Standard (C95. 1). The design of your phone complies with FCC guide-
` (and those standards).
`lines
`
`Antenna Care- Use only the supplied or an approved replacement
`antenna. Unauthorized antennas, modifications, or attachments could
`damage the phone and may violate FCC regulations.
`
`American National Standards Institute; National Council on Radiation Protection and
`
`Measurements; International Commission on Non-Ionizing Radiation Protection.
`
`Phone Operation- NORMAL POSITION: Hold the phone as you
`would any other telephone with the antenna pointed up and over your
`shoulder.

`
`

`
`TIPS ON EFFICIENT OPERATION: For your phone to operate
`most efficiently: Do not touch the antenna unnecessarily when the phone
`is in use. Contact with the antenna affects call quality and may cause the
`phone to operate at a higher power level than otherwise needed.
`
`Electronic Devices- Most modern electronic equipment is shielded
`from RF signals. However. certain electronic equipment may not be
`shielded against the RF signals from our wireless phone. Pacemakers: The
`Health Industry Manufacturer's Association recommends that a minimum
`separation of six (6") inches be maintained between a handheld wireless
`phone and a pacemaker to avoid potential interference with the pace-
`maker. These recommendations are consistent with the independent
`research by and recommendations of Wireless Technology Research. Per-
`sons with pacemakers: Should ALWAYS keep the phone more than six
`inches from their pacemaker when the phone is turned ON; Should not
`carry the phone in a breast pocket, Should use the ear opposite the pace-
`maker to minimize the potential for interference. If you have any reason
`to suspect that interference is taking place, turn your phone OFF imme-
`diately.
`
`Other Medical Devices- If you use any other personal medical
`device, consult the manufacturer of your device to determine if they are
`adequately shielded from external RF energy. Your physician may be able
`to assist you in obtaining this information. Turn you phone OFF in
`health care facilities when any regulations posted in these areas instruct
`you to do so. Hospitals and health care facilities may be using equipment
`that could be sensitive to external RF energy.
`
`iii
`
`UA-1008.005
`
`

`
`Vehicles- RF signals may affect improperly installed or inadequately
`shielded electronic systems in motor vehicles. Check with the manufacturer
`or its representative regarding your vehicle. You should also consult the
`manufacturer of any equipment that has been added to your vehicle.
`
`Posted Facilities- Turn your phone OFF in any facility where posted
`notices so require.
`
`Aircraft- FCC regulations prohibit using your phone while in the air.
`Switch OFF your phone before boarding an aircraft.
`
`
`
`Blasting Areas- To avoid interfering with blasting operations, turn
`your phone OFF when in a "blasting area" or in areas posted: "Turn off two
`way radio". Obey all signs and instructions.
`
`Potentially Explosive Atmospheres- Turn your phone OFF when in
`any area with a potentially explosive atmosphere and obey all signs and
`instructions. Sparks in such areas could cause an explosion or fire resulting
`in bodily injury or even death.
`Areas with a potentially explosive atmosphere are often, but not always
`clearly marked. They include fueling ares such as gasoline stations, below
`deck on boats: fuel or chemical transfer or storage facilities; vehicles using
`liquefied petroleum gas (such as propane or butane); areas where the air
`contains chemicals or particles, such as grain, dust, or metal powders; and
`any other area where you would normally be advised to turn off your
`vehicle engine.

`
`WARNING - For use in vehicles, it is the sole responsibility of the
`owner/operator of the NavTalk to secure the unit so that it will not inter-
`fere with the vehicle's operating controls, obstruct the operator's view of
`driving conditions, or cause damage or personal injury in the event of an
`accident. Do not mount the NavTalk over airbag panels or in the field of
`airbag deployment. Airbags expand with a rapid force that can propel
`objects in their path toward the driver or passengers causing possible
`injury. Refer to safety precautions contained in the vehicle owner's manu-
`al. Do not mount the NavTalk in a place where the driver or passengers
`are likely to impact it in an accident or collision. The mounting hardware
`provided by GARMIN is not warranted against collision damage or the
`consequences thereof.

`
`WARNING - When used in vehicles, it is the sole responsibility of
`the driver of the vehicle to operate the vehicle in a safe manner, maintain
`full surveillance of all driving conditions at all times, and not become dis-
`tracted by the NavTalk to the exclusion of safe driving practices. It is
`unsafe to operate the controls of the NavTalk while you are driving. Fail-
`ure by the driver to pay full attention to operation of the vehicle and to
`road conditions while the vehicle is in motion could result in accident or
`collision with property damage and personal injury
`
`UA-1008.007
`
`

`
`Caution - The Global Positioning System (GPS) is operated by the govern-
`ment of the United States, which is solely responsible for its accuracy and main-
`tenance. The system is subject to changes which could affect the accuracy and
`performance of all GPS equipment. Although the GARMIN NavTalk is a preci-
`sion electronic NAVigation AID (NAVAID), any NAVAID can be misused or mis-
`interpreted and, therefore, become unsafe.
`To reduce the risk of unsafe operation, carefully review and understand all
`aspects of this Operator's Manual and thoroughly practice operation using the
`simulator mode prior to actual use. When in actual use, carefully compare indi-
`cations from the NavTalk to all available navigation sources including the infor-
`mation from other NAVAIDs, visual sightings, maps, etc. For safety, always
`resolve any discrepancies before continuing navigation.
`
`Service and Repair - The NavTalk does not contain any user-serviceable
`parts. Repairs should only be made by an authorized GARMIN service center.
`Unauthorized repairs or modifications could void your warranty.
`
`FCC Compliance - The NavTalk GPS Receiver/Cellular Phone meets com-
`pliance requirements for maximum Specific Absorption Rate of radio wave emis-
`sions for the limit given in the FCC 96-326 Guideline. Tested by APREL Labora-
`tories, an agent of the Telecommunications Board of the Spectrum Scientific
`Institute, Nepean, Ontario, Canada.

`Section 1
`Introduction To NavTalk GPS Receiver/Cellular Phone
`
`The first time you power-up your NavTalk is an important step
`in getting off to the right start in achieving desired results and satis-
`factory operation. A basic understanding of the capabilities of the
`NavTalk and how its two main features function is essential to prop-
`er operation and maximum performance.
`
`Before you can actually turn on your unit, the power source
`(rechargeable battery pack) must be fully charged. So, you may want
`to jump ahead to Section 2.2, "Battery Charging and Installation" to
`begin that process, then read this manual while waiting for the bat-
`tery to complete its charging cycle.
`
`This section introduces you to the NavTalk List of Features and a
`basic overview of GPS Navigation and Cellular Phone usage. Because
`both NavTalk GPS and Cellular Phone functions are full-featured
`and go beyond conventional equipment, you will need to become
`familiar with their use before using this unit.

`
`Make sure you charge
`the NIMH battery pack
`for 14 to 16 hours
`(Trickle Charger) before
`using your NavTalk to
`ensure optimum capaci-
`ty and performance.

`
`1.2 Cellular Phone Overview
`Now it time to learn the basics of operating the cellu-
`lar phone. Let's begin with a brief overview of the cellular
`telephone system, Your NavTalk cell phone uses FM radio
`waves instead of conventional telephone lines to place and
`receive calls. A cellular telephone network consists of indi-
`vidual coverage areas (small sections of a city, typically sev-
`eral miles in diameter) called "cells".
`Each cell site has its own antenna located on a
`tower which is linked to a Mobile Telephone Switching
`Office (MTSO), which connects your call to the public
`switched telephone network or transfers it to another
`cellular phone.
`As you move from one location to another, your call
`is handed off to the next cell site to provide the best
`signal coverage and call quality. This arrangement of
`multiple cells allows you to travel throughout a geo-
`graphical area and maintain a quality conversation as
`the call is handed off from cell site to cell site. The sig-
`nal is affected by atmospheric and geographic condi-
`tions which exist at the time you place or receive a call.
`Remember, you must subscribe to a cellular system (to
`get a phone number) before you can use your cell
`phone. If you haven't been provided with a list of cellu-
`lar service providers by your Garmin Dealer then you
`need to determine which of the service providers in
`your area that you want to use. You may already have a
`service provider for a current cell phone and may want
`to have your NavTalk programmed to accept your cur-
`rent number or add a new one. Remember that:
`1. You can program up to three cellular numbers
`on the NavTalk.
`2.You need to have your battery pack charged and
`installed prior to taking your NavTalk to a Service
`Provider. Be certain to take along the trickle
`charger in the event that the service provider can
`not program your NavTalk immediately.
`3. Be certain to give the service provider the Service
`Provider Instruction Card packaged with your
`NavTalk.This will tell the service provider how to
`access special programming information needed
`to assign a phone number to the NavTalk.
`
`UA-1008.016
`
`

`
`4. The service provider will ask you questions about
`the type of service options you desire and then
`program your NavTalk accordingly.
`
`1.3 GPS Navigation Overview
`The Global Positioning System (GPS) is a system of
`24 satellites which circle the earth twice a day in a very
`precise orbit and transmit information to earth.
`The NavTalk must continuously "see" at least three
`of these satellites to calculate your position and track
`your movement. At times, additional satellites may be
`needed to determine a position.
`By using an almanac (a timetable of satellite num-
`bers and their orbits) stored in the receiver's memory,
`the NavTalk can determine the distance and position of
`any GPS satellite and use this information to compute
`your position.
`Your GPS receiver can only see satellites above the
`horizon, so it needs to know what satellites to look for
`at any given time. To use this almanac data, your GPS
`needs to either be told its general location ("initialized")
`or given the opportunity to find itself.
`Once you initialize the unit to a position, it will typ-
`ically compute a fix within a few minutes. We'll show
`you how to initialize your new NavTalk on page 65.
`Initialization is only necessary under the following
`conditions:
`• The first time you use your receiver (new from
`the factory).
`• After the receiver has been moved over 500
`miles (with the power off) from the last time
`you used it.
`• If the receiver's memory has been cleared and
`all internally stored data has been lost.
`
`Because the NavTalk relies on satellite signals to pro-
`vide you with navigation guidance, the receiver needs to
`have an unobstructed, clear view of the sky for best per-
`formance.
`
`UA-1008.017
`
`

`
`In a nutshell, the GPS receiver's view of the sky will
`generally detennine how fast you get a position fix—or if
`you get a fix at all. GPS signals are relatively weak and do
`not travel through rocks, buildings, people, metal, or
`heavy tree cover, so remember to keep a clear view of
`the sky at all times for best performance.
`Once the NavTalk has calculated a position fix, you'll
`usually have anywhere from five to twelve satellites in
`view. The receiver will then continuously select satellites
`in view to update your position. If some of the satellites
`in view get blocked or "shaded," the receiver can simply
`use an alternate satellite to maintain the position fix.
`Although a GPS receiver needs four satellites to pro-
`vide a three-dimensional (3D) fix, it can maintain a two-
`dimensional (2D) fix with only three satellites. A three-
`dimensional fix means the unit knows its latitude, longi-
`tude, and altitude, while a two-dimensional fix means the
`unit knows only its latitude and longitude.

`
`! Battery Installation:
`ore you can begin to explore the features and
`,rational characteristics of the NavTalk, you
`st first install the NiMH Battery Pack and
`Lrge it for 14 to 16 hours (Trickle Charger).
`
`1. Make certain the Battery Pack is securely in place
`in the cavity on the back of the NavTalk by aligning
`the two tabs of the base of the battery pack with
`the two small slots at the base of the cavity. Press
`the top portion of the battery pack in place until it
`clicks into position.
`
`2. Place the plug end of the charger assembly into
`the power connection slot at the bottom of the
`NavTalk, (the plug is indexed to fit only in one
`direction). Insert the transformer portion of
`the charger into a 120 VAC wall outlet.
`
`3. Allow 14 to 16 hours for the initial charging of the
`Battery Pack. NiMH batteries require conditioning
`during the first charging to establish maximum
`charge capacity.
`
`4. To determine if the battery pack has been fully
`charged, turn on the NavTalk and observe the bat-
`tery icon in the status bar at the bottom of the dis-
`play. The battery symbol should show solid black
`when fully charged.
`
`5. Indications that the battery pack requires
`recharging are: the battery status symbol will
`appear "empty", a "Low Battery" message will
`appear and a short intermittent warning tone will
`be heard. If no image appears on the screen when
`the power button is pressed, the battery may be
`fully discharged or the contras
