User manual ICOM MOBILE RADIO INSTALLATION

[. . . ] Such panels do not have the same shielding properties as metal and this may cause unexpected effect with RF such as VSWR, RF immunity. A qualified radio installation engineer should be able to give you advice on suitable products that can be used to "screen" such non-metallic panels if required. ` POSITION Checklist of points to decide before starting: i) Is there a suitable position to mount the radio?ii) Will you use a fist mic or a "hands-free" installation?iii) Can you route all cables so that they will not interfere with any controls of the vehicle? [. . . ] Such large antenna may also be subject to vehicle construction regulations. Please seek advice from a qualified vehicle engineer and a qualified mobile radio installer. Avoid mounting the antenna where it could be dangerous for pedestrian or other road users. 2 ` CABLING Mobile transceivers generally need a direct connection to the vehicle battery. You need to check where you can route the DC supply cable and RF coaxial cables. If there are no specific instructions for your vehicle and/or radio then the following points should be adhered to : i) ii) iii) iv) v) vi) Keep the radio cables away from fuel or gas pipes. Keep the radio cables away from any part that will become hot. Keep the radio cables clear of moving parts (steering, suspension, throttle control, etc. ) Route the cables where they can be securely held in position. Check if you need to drill some holes for passing radio cables. Only attach cables to non-moving parts of the vehicle. ` INSTALLATION Start the installation with any mechanical work that is required for fitting the radio mount, cables, etc. Before drilling any hole in a vehicle check exactly what is behind the panel that you are drilling. When drilling a hole always use a drill with a "stop" so that it is impossible for the drill to go too far. Take extra care to avoid petrol tanks and pipes, brake lines, other wiring, etc. If you have to drill any hole to pass a cable then the hole must be sealed with a rubber grommet and when the cable has been passed through you should re-seal the cable and grommet with a suitable sealant. If you drill holes for mounting screws, be sure to check that the screw is a suitable type and length. Locking type screws, nuts or washers are preferred. Pay attention to cables inside the passenger compartment. They should be secured or routed under carpets etc. There should be no possibility that they could move and interfere with any control or pedal. 3 ` BATTERY CONNECTION Mobile transceivers are usually intended for direct connection to the battery. Before disconnecting the battery you need to be aware of some possible problems: i) Is the vehicle fitted with an alarm that may not operate after re-connection?ii) Is the vehicle fitted with any electronic circuit that may malfunction after re-connection?(engine management, traction control, braking control, etc. ) iii) If in doubt do not disconnect the battery. Take the vehicle to an authorised service agent and ask them to connect the transceiver power cables for you. If the DC cables are not long enough they should only be extended using an equivalent size and type of cable and any join must be capable of handling the specified current and be well insulated. [. . . ] Check that no unintended flashing or indication occurs. If the above checks have been completed without problem you can proceed to the mobile operational checks. ` MOBILE OPERATIONAL CHECKS DO NOT PERFORM THESE CHECKS IN CITY TRAFFIC!Find a quiet road, start the vehicle and while moving slowly operate the transmitter. If all is OK, then increase to normal driving speed and repeat the tests. [. . . ]
