Warnings

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 previously 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 evaluations 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 NavTalk Pilot phone complies with FCC guidelines and those standards.

FCC Compliance Statement— The NavTalk Pilot GPS Receiver/Cellular Phone meets compliance requirements for maximum Specific Absorption Rate of radio wave emissions for the limit given in the FCC 96-326 Guideline. Tested by APREL Laboratories, an agent of the Telecommunications Board of the Spectrum Scientific Institute, Nepean, Ontario, Canada.

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.

Phone Operation— Hold the phone as you would any other telephone with the antenna pointed up and over your shoulder.

* American National Standards Institute; National Council on

Radiation Protection and Measurements; International Commission

on Non-Ionizing Radiation Protection.

Introduction

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 pacemaker. These recommendations are consistent with the independent research by and recommendations of Wireless Technology Research. Persons 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, and should use the ear opposite the pacemaker to minimize the potential for interference.

AirCell airborne service is available to your airborne phone only when the phone is within operating range of the AirCell cellular base stations.

AirCell service relies on radio frequencies, and is subject to transmission limitations caused by atmospheric, geographic and topographic conditions. Airborne coverage is designed for altitudes above 5,000 ft. AGL, and service will improve with increasing altitude above ground.

If you have any reason to suspect that interference is taking place, turn your phone OFF immediately.

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.

Posted Facilities— Turn your phone OFF in any

facility where posted notices so require.

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.

Introduction

Cautions

and

Warnings

Notice!

The service does not guarantee 9-1-1 or other emergency response capabilities, and the phone is not intended to be flight critical equipment.

Although laws prohibit listening in on telephone calls, your privacy cannot be guaranteed.

Noise or other interference may be observed at the airborne unit when flying over major metropolitan areas. Such interference may affect the quality of the call.

Operation of this service may be temporarily refused, limited, interrupted or curtailed as appropriate for the proper operation of this service and for other business purposes. The AirCell service will be limited, at least initially, and may change from time to time. Airborne cellular service is currently provided under a waiver granted by the FCC, and is subject to the renewal of that waiver by the FCC on a biennial basis.

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 areas 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 graindust or metal powders and any other area where you would normally be advised to turn

off your vehicle engine.

Aboard Aircraft— Federal Communications Commission (FCC) regulations prohibit the use of conventional cellular telephones while an aircraft is in flight. Signals from conventional cellular telephones travel much further when airborne and may interfere with cellular communications on the ground. These signals may also interfere with other equipment aboard the aircraft. Regulations authorize the air cellular feature of the NavTalk Pilot to be used in flight.

Operation of the NavTalk Pilot aboard an aircraft in flight is permitted only when connected to the aircraft adapter supplied with the NavTalk Pilot system. In this configuration transmit power is

reduced and routed to an external, horizontally polarized antenna, minimizing the potential for interference.

Driving— Check the laws and regulations on the use of wireless telephones in the areas where you drive. Always obey them. Also, if using your phone while driving, please: Give full attention to driving-- driving safely is your first responsibility. Use hands-free operation, if available. Pull off the road and park before making or answering a call if driving conditions so require.

Introduction

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.

Warning— For use in vehicles, it is the sole

responsibility of the owner/operator of the NavTalk Pilot to secure the unit so that it will not interfere with the vehicle’s operating controls, obstruct the driver’s view of driving conditions, or cause damage or personal injury in the event of an accident. Do not mount the unit 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 airbag safety precautions contained in the vehicle owner’s manual. Do not mount the NavTalk Pilot in a place where the driver or passengers are likely to impact it in an accident or collision. The optional 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 distracted by the unit to the exclusion of safe operating practices. It is unsafe to operate the controls of the unit while you are driving. Failure by the driver of a vehicle equipped with a NavTalk Pilot to pay full attention to operation of the vehicle and road conditions while the vehicle is in motion could result in an accident or collision with property damage and personal injury.

Caution— The Global Positioning System (GPS) is

operated by the government of the United States, which is solely responsible for its accuracy and maintenance. The system is subject to changes that could affect the accuracy and performance of all GPS equipment. Although the

Section 1 - Introduction to the NavTalk Pilot

The first time you power-up your NavTalk Pilot is an important step in getting off to the right start in achieving desired results and satisfactory operation. A basic understanding of the capabilities of the NavTalk Pilot and how its two main features function is essential to proper 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 “Battery Installation” on page11 to begin that process, then read this manual while waiting for the battery to complete its charging cycle.

This section introduces you to the NavTalk Pilot List of Features and a basic overview of GPS Navigation and Cellular Phone usage. Because both NavTalk Pilot 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.

Cellular Phone Overview

Now it’s time to learn the basics of operating the cell phone. Let’s begin with a brief overview of the cellular telephone system. Your NavTalk Pilot cell phone uses radio waves instead of conventional telephone lines to place and receive calls. A ground based cellular telephone network consists of individual coverage areas (small sections of a city, typically several miles in diameter) called “cells”. An air based cellular network is structured in a similar manner with separate air cellular frequencies that are linked to a conventional cellular network.

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 geographical area and maintain a quality conversation as the call is handed off from cell site to cell site. The signal is affected by atmospheric and geographic conditions that exist at the time you place or receive a call. The NavTalk Pilot is preprogrammed with a Number Assignment Module (NAM) for AirCell® service. You can only use AirCell service when the unit is connected to the AirCell adapter installed in your aircraft. To view the current status of AirCell coverage access the AirCell website at: www.aircell.com.

Remember, you must subscribe to a ground cellular system (to get a ground based phone number) before you can use your cell phone for ground based cellular phone calls. If you haven’t been provided with a list of ground cellular 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 you may want to have your NavTalk Pilot programmed to accept your current number or add a new one.

Section 1

Remember that:

1. There are three cellular Number Assignment Modules (NAM’s) on the NavTalk Pilot. Two modules are reserved for ground cellular service and one for AirCell service which is pre-programmed at the factory.

2. If you want to use AirCell as your cellular provider on the ground, you may subscribe to AirCell’s ground cellular system. Otherwise, you may want to have your ground cellular phone number “Call Forwarded” to your NavTalk Pilot AirCell number to eliminate the need to provide potential callers with two phone numbers.

3. You need to have your battery pack charged and installed prior to taking your NavTalk Pilot to a Service Provider. Be certain to take along the trickle charger in the event that the service provider can not program your unit immediately.

4. Be certain to give the service provider the Service Provider Instruction Card packaged with your NavTalk Pilot. This will tell the service provider how to access special programming information needed to assign a phone number to the NavTalk Pilot.

5. The service provider will ask you questions about the type of service options you desire and then program your NavTalk Pilot accordingly.

GPS Navigation Overview

The Global Positioning System (GPS) is a system of 24 satellites that circle the earth twice a day in a very precise orbit and transmit information to earth.

The NavTalk Pilot 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 numbers and their orbits) stored in the receiver’s memory, the NavTalk Pilot can determine the distance and position of any GPS satellite and use this information to compute your position.

xvii

Section 1

Introduction to

NavTalk Pilot

xviii

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 typically compute a fix within a few minutes. You’ll learn how to initialize your new NavTalk Pilot on page 61.

Initialization is only necessary under the following conditions:

• The first time you use your receiver.

• 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 Pilot relies on satellite signals to provide you with navigation guidance, the receiver needs to have an unobstructed, clear view of the sky for best performance.

In a nutshell, the GPS receiver’s view of the sky will generally determine 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 Pilot 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 provide 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, longitude, and altitude, while a two-dimensional fix means the unit knows only its latitude and longitude.
