Safety Warnings Warning: Safe Operation ■ Switch the radio off at petrol filling stations or near flammable liquids or gases. ■ Switch the radio off in the vicinity of explosive devices and blasting zones. ■ Using a handheld microphone or a radio while driving a vehicle may violate the laws and legislation that apply in your country or state. Please check the vehicle regulations in your area.
■ This minimum safe distance is based on the assumption that there is a duty cycle of 50% transmit mode to stand-by or receive modes. The radio is in transmit mode when the PTT (press-to-talk) key on the microphone is pressed and the control head red LED (light emitting diode) glows. Please refer to the following website for more information on what RF energy is and how to control your exposure to assure compliance with established RF exposure limits.

Getting Started This section provides a brief description of your radio’s basic operation. If you need further information, contact your radio provider. Radio Controls The radio controls are the PTT key, volume control, on/ off key, channel selection keys and function keys. Some keys may have functions assigned to both short and long key presses. A short key press is defined as less than one second and a long key press is more than one second.

Radio Indicators The LED indicators and the radio’s audible tones all combine to give you information about the state of your radio. The way these indicators behave is affected by the way your radio is programmed. The following sections describe the most common operation of the radio indicators.
Basic Operation This section describes the basic operation of your radio, including turning the radio on and off, adjusting volume, selecting channels, making calls and receiving calls. Turning the Radio On and Off A long press of the on/off key turns the radio either on or off. When the radio is first turned on, the red, green and amber LEDs flash briefly and the radio gives two short beeps.
Transmit Timer Your radio may have a transmit timer that limits the amount of time you can transmit continuously. When the transmit timer is about to expire, the red LED flashes and the radio gives three beeps. You must release the PTT before you can transmit again. Note: Your radio may be unable to transmit for a short time after the transmit timer has expired.
Squelch The radio’s squelch allows the radio to unmute only when the strength of the incoming signal is above a predetermined threshold. This means that only signals of reasonable intelligibility are made audible. Monitor The monitor function is used to check that the channel is clear before you make a call. While monitor is on, the green LED flashes continually. Activating Monitor 1. Press the monitor function key and monitor overrides the signalling mute, allowing you to hear any traffic on the channel.
Scanning The scan function is used to monitor a programmed group of channels, looking for activity. When activity is detected on one of the scan group channels, the radio stops on that channel. The amber LED flashes and, if the channel signalling is valid, the radio unmutes and you can hear the call. Scanning resumes when the channel is no longer busy or the signalling is no longer valid. Activating Scanning 1. Place the microphone on the microphone clip.
Troubleshooting If the red, green and amber LEDs on the control head do not light up when the radio is turned on, it is likely that no power is reaching the radio. Check the following: ■ Is the power connector firmly plugged into the rear of the radio? ■ Are the in-line fuses in good condition? ■ Is the power cable securely connected to the vehicle battery or power supply? If all appears to be in order, then contact your radio provider for further assistance.

Part 2: Radio Installation Procedures Installation Warnings .................................................................18 Warning: Safe Radio Mounting ............................................................18 Warning: Interference With Vehicular Electronics .................................18 Warning: Liquefied Petroleum Gas Powered Vehicles ...........................18 Caution: Non-Standard Radio Installations ...........................................19 Caution: Negative Ground Supply .......
Installation Warnings Warning: Safe Radio Mounting ■ Mount the radio securely so that it will not break loose in the event of a collision. An unsecured radio is dangerous to the vehicle occupants. ■ Mount the radio where it will not interfere with the deployment of passenger air bags. ■ Do not mount the radio vertically, with the control head facing down. This will violate compliance with the European Union standard EN 60950, Safety of Information Technology Equipment.
NFPA 58. This standard states that the radio equipment installation must meet the following requirements. ■ The space containing the radio equipment shall be isolated by a seal from the space containing the LP gas container and its fitting. ■ Outside filling connections shall be used for the LP gas container and its fittings. ■ The LP gas container space shall be vented to the outside of the vehicle.
Installation Planning The procedures outlined in this and the following sections are for installing a TM8105 or TM8115 radio in a vehicle, using a standard U-bracket. MPT 1362 Code of Practice TM8100 radios should be installed in accordance with the MPT 1362 Code of Practice. This code of practice covers the installation of mobile radio equipment in land based vehicles and has been developed by the United Kingdom Radiocommunications Agency.
Microphone Clip Installation Tools ■ Centre punch ■ Drill bit ■ Pozidriv screwdriver ■ Hammer Mounting Position Inspect the vehicle and determine the safest and most convenient location for mounting the radio. The installation must meet the following requirements: ■ sufficient clearance behind the radio for the heatsink and cables ■ a large enough flat surface so that the mounting bracket will not be distorted ■ no danger of the radio interfering with air bag deployment.
Radio Installation Mounting Screw the U-bracket in the chosen mounting position the U-bracket using the self-tapping screws provided. At least four screws must be installed. Note: If the U-bracket is being mounted over a curved surface, the U-bracket tabs can be bent slightly. Caution: Check that the tightening of the screws does not distort the U-bracket.
Removing the Control Head 2 1 Caution: During this procedure, take care that the chassis seal is not damaged. Damage to this seal reduces environmental protection. 1. On the underside of the radio, insert a flat-bladed screwdriver between the control head and the radio chassis seal, in either position 1 or 2 . Note: Insertion points 1 and 2 are indicated on the radio chassis by a dot-dash-dot pattern (• •). – 2.
1. Plug the microphone into the microphone socket on the control head. 2. Slide the microphone grommet along the microphone cord and push two adjacent corners of the grommet into the microphone socket cavity. 3. Squeeze the grommet and push the remaining corners into position. 4. Check that the grommet is seated correctly in the cavity. microphone grommet control head Installing the Install the external antenna according to the supplier’s Antenna instructions.
Power Cable Caution: This radio is designed to operate from a nominal 12V negative ground supply and may draw up to 8A of current. The radio will tolerate a supply voltage range of 10.8V to 16.0V at the radio. In vehicles with a supply voltage greater than 16.0V, such as many trucks, it is essential to provide a suitably rated DC to DC converter. This will isolate the radio from excessive battery voltage and provide the correct DC operating conditions.
3. Cut the negative and the positive wires where the inline fuse holders will be placed (as close to the battery as possible). Note: Do not install the fuses until the installation is ready to be checked. 4. Insert each end of the negative wire into one of the in-line fuse holders and crimp them to force the metal contacts onto the wires. 5. Connect the negative wire to the battery ground. 6. Repeat step 4 for the positive wire and connect it to the positive terminal of the battery.
Microphone Install the microphone clip in the most convenient locaClip (TM8115 tion for the radio user. It must be within easy reach of Radios Only) the user, but in such a position that the microphone PTT key cannot be inadvertently activated or jammed on. TM8105 Remote Connector The TM8105 has a 9-way D-range socket on the control head, for remote connection. The pin allocations of the remote connector are shown in the following diagram and table.
Installation Checks 1. Insert the fuses into the power leads. 2. TM8115 radios only. Switch on the radio to confirm that it is operational (see “Turning the Radio On and Off” on page 11). Caution: Do not transmit yet. 3. Connect an in-line power meter between the radio and the antenna and measure the forward and reflected power levels. Less than 4% of the forward power should be reflected. If this is not achieved, check the installation, including the antenna length. 4. TM8115 radios only.
