SECTION 2 – INSTALLATION INFORMATION
2.1 INTRODUCTION
This section gives the basic installation information for units of VHF/AM Mobile Transceiver
System 910200 in a typical airport service vehicle. As there are many types of vehicles in use, some may require "tailor made" installation information.
The first consideration when planning an installation in a vehicle is the location of the transceiver.
The transceiver is normally located under the dashboard of a vehicle with the transceiver supported under the mounting bracket, as shown in Figure 1.2. Where space under the dashboard is limited, the transceiver could be supported above the mounting bracket, the reverse of Figure 1.2.
Consideration should also be given to allowing sufficient space behind the transceiver for the length of the antenna connector and the power supply connector when they are mated to the transceiver connectors.
Having determined the location of the transceiver, the point of connection to the vehicle power supply may be chosen. The transceiver will operate from a 12 volts dc nominal power supply with negative ground, which must be taken from a fused power source with a minimum of 5 ampere fuse in circuit. The transceiver will tolerate an input voltage over the range 11.0 to 15.0 Vdc.
2.4 POWER INPUT CABLE ASSEMBLY
Using Power Input Cable Assembly, Part Number 863701, as shown in Figure 1.3, route the unterminated end of the cable from the transceiver location to the point of connection to the fused vehicle power supply. The 10 ft cable may be cut to length as required. Coiling of excess cable is
NOT recommended. Strip the outer covering from the end of the cable, prepare the individual wire ends, and fit suitable terminals. Connect the red wire to the positive supply (fused), and connect the black wire to the negative supply ground.

TiL 94RE146 Rev E
TECHNISONIC INDUSTRIES LIMITED www.til.ca
Antenna Assembly, Part Number 861910-1, is supplied as a kit which includes an installation leaflet. The antenna is shown assembled in Figure 1.5.
The antenna location is a very important factor in determining the performance of the system. The antenna may be mounted on any flat surface, roof, cowl, fender or rear deck of the vehicle, however, rooftop mounting is recommended for best performance.
Having determined the location of the antenna, route the unterminated end of the antenna RF cable from the transceiver location. Using the antenna installation leaflet, follow the step by step instructions, and install the antenna. Any excess length of antenna RF cable should be cut-off before connection to the antenna.
Mounting Bracket, Part Number 913053-1, should be installed in the transceiver location using
Qty 4 Screws, Self-Tapping, Hex Hd with slot and shoulder No. 12 x 3/4in. included in Mounting
Hardware Kit, Part Number 869024-1. Refer to Figure 1.2 for a view of the transceiver with mounting bracket.
Using the mounting bracket as a template; on the mounting surface, mark the centre of each of the four slotted mounting holes, and drill a pilot hole using a No. 19 drill or equivalent (actual pilot hole size depends on the thickness of metal of mounting surface). Locate mounting bracket in position, and secure using the screws provided.
Locate the transceiver in its approximate position, connect the antenna connector, and power cable connector to the appropriate connectors located at the rear of the transceiver.
Locate the transceiver into mounting bracket, and screw to bracket using two wing screws and nylon washers included in Mounting Hardware Kit, Part Number 869024-1. Adjust angle of transceiver as required, before tightening the two wing screws.
Refer to Figure 1.4 for a general view of the microphone and retaining bracket. Determine a suitable and convenient location for Retaining Bracket and secure it using appropriate hardware
(not provided). Connect the connector of Microphone, Part Number 961070-1 to the MIC/PTT connector located on the front panel of the transceiver.

2.9 OPTIONAL EXTERNAL LOUDSPEAKER OR HEADPHONE
Provision is made for connection of either an external loudspeaker or headphone to the
SPEAKER/PHONE jack of the transceiver, as shown in Figure 3.1.
When an external loudspeaker is to be installed, an 8-ohm nominal impedance loudspeaker should be used. The loudspeaker cable should be terminated by a 1/4 in., 3 pole telephone plug
(male), with the loudspeaker connected between tip and sleeve (ground). The External loudspeaker connector should be connected to the SPEAKER/PHONE jack located on the front panel of the transceiver. When the external loudspeaker connector is connected to the transceiver SPEAKER/PHONE jack, the internal loudspeaker is automatically disconnected.
2.9.2 Headset
When a headset is to be used, the headset impedance should be 150 to 600 ohms. The headset cable must be terminated by a 1/4in., 3 pole telephone plug (male), which mates with the
SPEAKER/PHONE jack located on the front panel of the transceiver. When connected, the internal loudspeaker is automatically disconnected. The headset may be connected as detailed in
(1) for receiver audio with no transmit sidetone audio, or (2) for receiver audio with transmit sidetone audio.
(1) HEADSET WITH NO TRANSMIT SIDETONE AUDIO - When receiver audio only with no transmit sidetone audio is required, the headset should be connected between the tip and sleeve (ground) of the telephone plug.
(2) HEADSET WITH SIDETONE AUDIO - When receiver audio with transmit sidetone is required, the headset should be connected between the tip and sleeve (ground) with a resistor (located inside the plug) connected between the tip and ring of the telephone plug. The function of the resistor is to reduce the transmit sidetone audio level to a suitable listening level. The value of the resistor is determined by the headset impedance and desired listening level. When a 600 ohm impedance headset is used, the value of the resistor should be approximately 10 kilohms. For headsets with lower impedance, the resistor value may be different but must not be less than 240 ohms.
Perform an operational check of the transceiver, checking each channel in use in both the transmit and receive modes of operation, using the Operating instructions given in Section 3 of this document and the appropriate specified operating procedures during transmission.
