For passenger safety, mount the radio securely so that the unit will not break loose in the event of a collision. This is especially important in station wagons, vans and similar type installations where a loose radio could be extremely dangerous to the vehicle occupants. WARNING INSTALLATION IN VEHICLES POWERED BY LIQUEFIED (LP) GAS Radio installation in vehicles powered by liquefied petroleum gas with the LP-gas container in the trunk or other sealed-offspace within the interior of the vehicle must conform to the National Fire Protection Association Standard NFPA 58 which requires that: • Space containing radio equipment shall be isolated by a seal from the space containing the LP-gas container and its fittings. • Outside filling connections shall be used for the LP-gas container. • The LP-gas container space shall be vented to the outside of the vehicle. 9

cables be run before mounting the radio. Be sure to leave some slack in each cable going to the radio so that the radio may be pulled out for servicing with the power applied and antenna attached. Try to route the cables away from locations where they will be exposed to heat (exhaust pipes, mufflers, tailpipes. etc.). battery acid, sharp edges, or mechanical damage or where they will be a nuisance to automobile mechanics. the driver, or passengers. Keep wiring away from electronic computer modules. other electronic modules and ignition circuits to help prevent interference to these components and radio equipment. In addition. try to utilize existing holes in the fire wall and trunk wall and the channels above or beneath the doors. Also, channels through door and window columns that are convenient for running cables may be used, unless planning to install rigid or flexible conduit in which to run the cables. Power And Ignition Cable The power cable consists of a red lead, an orange lead, a black lead, a 3 pin systems plug. and a set of fuses and fuse holders to be installed as indicated in Figure 3. To install the power cable, drill a 5/8 inch hole in the firewall for the cable run and insert the rubber grommet. Starting with the plug end of the cable at the location of the radio, run the three cable leads through the hole. Secure the cable at several locations within the engine compartment. To install the fuses: 1. Cut off 12 to 18 inches from the red and orange wires. 2. Strip back the insulation approximately 3/8 of an inch on each end of the wires. 3. Lubricate the wire tips with liquid soap to insert the wires into the fuse holders. Pull the wire ends through the small opening at the end of each fuse holder section and crimp a fuse connector to each wire. 10 P (1 in M m N (1 w

4. Push the prepared fuse connectors into each section of the fuse holders. Place the fuse into a fuse holder section until it seats within the connector. Connect the fuse holder sections to insure a tight fit and connection. 11

PMPD1A (19A148539G1) may be needed for satisfactory performance. NOTE With some accessory points, the voltage only drops when the ignition switch is in the START position. A connection point should be used where the voltage is completely off when the ignition switch is in the START position. Certain problems may be encountered when accessory equipment is connected to the ignition or accessory lines of the vehicle, where these lines may have large filter capacitors or a leakage path present. If the radio does not turn off within a reasonable amount of time after the ignition is turned off, first try a different accessory or ignition sense pick up point in the vehicle. Many vehicles have more than one circuit that is switched by the ignition switch, and one may be available that does not have large filter capacitors or a leakage path present. If a different pickup point cannot be found, then add a 470-ohm 1-watt resistor from the ignition sense pick point to ground. This will discharge the capacitor(s) or reduce the leakage voltage to a low value. Current drain through this resistor will be minimal (less than 0.03A) when the ignition is switched on. CAUTION Connect the orange fused lead to the positive (+) battery terminal, and black to the negative (-) battery terminal. Always locate the fuse as close to the battery as possible. Connect the red fused lead to the ignition on" sense point (preferably an "Accessory" point on the fuse panel that is switched on when the ignition switch is in the accessory position and in the "run" position). Locate the fuse as close as possible to the accessory point. 12 of in ob gl sh pa w ut ve to O th op in (M co 2 1. 2. 3. 4.

Coil any surplus cables and secure them out of the waywith the retaining strap provided. Be sure to leave some slack in the cables going to the radio so that it may be pulled out for servicing with power applied. MOUNTING THE RADIO Use the supplied mounting bracket as a template to locate the positions for each of the drill holes. Mount the radio as shown in Figure 5. Be sure to leave enough room at the rear of the radio for the cable connections. 13

MICROPHONE HANGER Mount the microphone hanger in a location convenient to the operator where it will not interfere with the safe operation of the vehicle orbe a hazard to the vehicle passengers. The microphone hanger is designed to be mounted with the open end of the mounting button slot pointed upward. The microphone hanger is shown in Figure 6. 14 U 1 2

NOTE If mounting on a surface covered with carpet, punch holes with a small punch then make a small slit in the carpet, insert a short piece of metal tubing and drill through the tubing. Use the following procedure to mount the microphone hanger: 1. Use the hanger as a template to mark the screw locations and drill the small pilot holes. 2. Use the self tapping screws to mount the hanger in an upright position. 15

MICROPHONE The microphone connects to the MDX Mobile Radio using a plug found at the end of its attached cable. Match the pins on this plug to the pin socket on the radio and press in the plug being sure not to damage the pins. Once the plug is seated, tighten down the plug using the thumbscrew on the mic connector. To remove the plug reverse this procedure. MOBILE OPTIONS INSTALLATION ANTENNA-OPTION PMAN1L (19B209568P5) Installation instructions for the antenna are packed with the antenna. The antenna must be installed in accordance with good engineering practice for opti- mum results. 16 C pr be M of ro

of center of rear deck. Glass mounted antennas should be kept as high as possible in the top center of the rear window. Some states have laws restricting vision obstructing items from the windows. Be familiar with local laws before installing glass mount antennas. Try to route the cable away from locations where it will be exposed to heat, sharp edges or mechanical damage, and where it will be out of the way of the driver, passengers or vehicles mechanics. Wherever possible, existing holes in the trunk- wall, and the channels above or beneath doors and window columns should be utilized. Avoid routing the antenna cable near any electronic modules or along side any vehicle wiring. Connect the antenna cable to the TNC connector on the radio being careful not to twist the cable.
