6880907Z66-O June, 2000

GTX Mobile Radio Installation Manual least the minimum distance away from a properly installed, externally-mounted antenna.

Table 1-1 lists the minimum distance for several different ranges of rated radio power.

Selecting an Antenna Site

1.

Install the vehicle antenna external to the vehicle and in accordance with the requirements of the antenna manufacturer/supplier

2.

The best mounting location for the antenna is in the center of a large, flat conductive surface.

In almost all vehicles, mounting the antenna in the center of the roof will satisfy these requirements. A good alternative location is in the center of the trunk lid. If you use the trunk lid, ensure that the trunk lid is grounded by connecting grounding straps between the trunk lid and the vehicle chassis.

3.

Ensure the antenna cable can be easily routed to the radio. Ensure that the antenna cable is routed separately and not in parallel to any other vehicle wiring or mobile radio cable wiring.

4.

Check the antenna location for any electrical interference.

NOTE

Any two metal pieces rubbing against each other (such as seat springs, shift levers, trunk and hood lids, exhaust pipes, etc.) in close proximity to the antenna can cause severe receiver interference.

5.

If the vehicle is equipped with an electronic anti-lock braking system (ABS), mount the antenna at the center of the roof or trunk lid and do not route the antenna cable near the

ABS Modulator Box. Mount the radio as far away from the Modulator Box as physically possible. This minimizes radio interference to the modulator box from the radio.

6.

Make sure the mobile radio antenna is installed at least one foot (30.48cm) away from any other antenna on the vehicle.

Section 2

Installation

Your mobile two-way radio offers various installation possibilities. The standard radio package contains a direct mounting trunnion and power cables. Ensure that the cables can be routed to the radio without being exposed to excessive heat or mechanical damage.

Before You Start

Licensing

For the United States only: The Federal Communications Commision (FCC) regulations state that a station license must be obtained for each radio installation by the owner of the equipment. The station licensee is responsible for ensuring the transmitter power, frequency, and deviation are within the limits permitted under the station license. For outside the United States:

Adhere to the applicable rules of your local licensing authority.

Your radio is completely adjusted, tested, and inspected before shipment. No technician's license is required for installing and maintaining radio equipment. However, the frequency and deviation of the transmitter must be checked at the time of installation and at least annually.

Power Protection Circuitry

The GTX mobile you are installing has been tested for proper transmitter power output before leaving the factory. Each radio is set to the proper output power level while connected to an accurate 50 Ohm load impedance. Once the power level has been set, the internal power control/protection circuitry will reduce the power output whenever it senses a load impedance significantly different from 50 Ohm. This protection circuitry greatly enhances the radio's reliability with minimal performance degradation.

If you check transmitter output power levels during installation, be sure you are using a good 50 Ohm load, with a minimum of adapters and using short test cables. Any load variation from 50 Ohm may cause an apparent reduction in output power due to the normal operation of the control/protection circuitry. A load impedance of 50 Ohm is required for all bands. However, it has more effect in 800/900 MHz radios since cables, meters, connectors, etc. have larger effects in these bands. If power seems to be unusually low

(greater than can be explained by the normal calibration differences you experience), check your test setup.

If power output goes up as you improve the quality of the load impedance (be sure to de-key when making any changes in load), the control/protection circuitry is performing normally.

Typical mismatches in the load impedance (greater than 1.2:1 VSWR) may result in a 10-20% variation in the actual measured power output. Within these limits, the radio operates normally and you should not attempt to service it.

Installation Planning

Planning

Planning is the key to fast, easy radio installation.

Before a hole is drilled or a wire is run, inspect the vehicle and determine how and where you intend to mount the antenna, radio, and accessories. Plan wire and cable runs to provide maximum protection from pinching, crushing, and overheating.

Recommended Tools For Installation

The following tools are recommended for proper installation of your new radio.

• Portable Drill

• Hammer

• Center Punch

• 5/ 16" (8 mm) Hex Nut Driver

• 1 /4" (7 mm) Hex Nut Driver

• Phillips #2 Screwdriver

• TORX Screwdriver, T25

• 3/8" (9 mm) Diameter Drill Bit

• 5/16" (8 mm) Diameter Drill Bit

• 5/32" (4 mm) Diameter Drill Bit

Installation

Starting The Installation

Radio Mounting

Mounting Trunnion

The mounting trunnion allows the radio to be mounted to a variety of mounting surfaces. Be sure the mounting surface is able to adequately support the weight of the radio. Allow sufficient space around the radio for free air flow for cooling. Be sure the unit is close enough to the vehicle operator to permit easy access to the operating controls.

CAUTION

Do not mount the trunnion to a plastic dash board. In an accident, the radio and trunnion could break loose and b e c o m e a p o t e n t i a l fl y i n g h a z a rd .

Always secure the trunnion to the metal support frame of the dashboard.

Standard Mounting Trunnion

The standard mounting trunnion should be used for installing only the low power (12 W and 15 W) radios.

3-Point Mounting Trunnion

The high power (30 W and 35 W) radios must be installed with the 3-point mounting trunnion.

Starting The Installation

DC Power Cable Installation

The radio must be operated only in negative ground electrical systems. Reverse polarity does not damage the radio however, radio protection circuits cause the cable fuse to open. Check the vehicle ground polarity before you begin installation to prevent wasted time and effort.

The 3 meter (10 feet) UIC power cable shipped with the radio is long enough for installation in most vehicles.

Begin the power cable installation in the following manner.

1.

Determine a routing plan for the power cable with reference to where the radio is to be mounted.

2.

Locate an existing hole with a grommet in the vehicle firewall, or drill a 3/8” access hole at the location for passing the power cable into the engine compartment. Install a grommet with a 1/4" (7mm) inner diameter in the access hole to avoid damage to the cable.

CAUTION

High degree of care should be exercised not to damage any existing vehicle wires.
