Interference with Vehicular Electronics - Electronic fuel injection sys-
tems, electronic anti-skid braking systems, electronic cruise control sys-
tems, etc., are typical of the types of electronic devices which may be
prone to malfunction due to the lack of protection from radio frequency
energy present when transmitting. Ifthevehicle containssuchequipment,
consult the dealer for themake of vehicleand enlist his aid in determining
if such electronic circuits will perform normally when the radio is trans-
mitting.
WARNING

•out of the way of auto mechanics.
•out of the way of passengers.
It is suggested that theradio beinstalledby oneofthe many authorizedGeneral
Electric Service Stations located throughout the United States. These experienced
service stations can provide a proper radio installation and make any final adjust-
ments that may be needed.

Be careful to avoid damaging some vital part (fuel tank, transmission
housing, etc.) of the vehicle when drilling mounting holes. Always check
to see how far the mounting screws will extend below the mounting
surface before installing.
CAUTION
Ifpilotholesmustbedrilled,removeallmetalshavingsfromdrillingholes
before installing screws.
CAUTION
Radio installations in vehicles powered by liquefied petroleum gas must
conform to the following requirements.
WARNING
EQUIPMENT REQUIRED
The equipment required for installing the MDX Mobile Radio is listed
below:
•Electric drill for drilling mounting holes.
•Drills and circle cutters as follows:

•No. 27 (9/64-inch) drill for No. 10 self-tapping screws.
•5/8-inch drill or circle cutter for power cable.
•3/4-inch circle cutter, hole saw or socket punch for antenna (op-
tional).
•Phillips and flat-blade screwdrivers, and 1/4-inch and 5/16-inch hex-
head drivers for mounting screws.
•No. 15 Torx® driver (ST0606).
•No. 15 Torx® tamper-proof driver (ST0618) if latch security screw
(supplied in hardware kit) is used.

Figure 2 - Typical Hump Or Dash Mount
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 StandardNFPA
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.

INSTALLATION
RUNNING CABLES
To assure the feasibility of the planned cable routings. it is suggested that the
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
systemsplug.anda setoffusesandfuseholderstobeinstalledasindicatedinFigure
3.
To install the power cable, drill a 5/8 inch hole in the firewall for the cable run
and insert therubber grommet. Startingwith the plug end of the cable atthelocation
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 theinsulation approximately 3/8 of an inch oneach end of the wires.
3. Lubricate the wire tips with liquid soap to insert the wires into thefuse 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.

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.

NOTE
In some installations an additional noisesuppression filter such as option
PMPD1A (19A148539G1) may be needed for satisfactory performance.
NOTE
With some accessory points, the voltage only drops when the ignition
switchisintheSTARTposition.Aconnectionpointshouldbeusedwhere
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
thecapacitor(s) or reduce the leakagevoltage toa lowvalue.Currentdrain
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.

EXTERNAL SPEAKER KIT - OPTION PMZM1K
The external speaker kit includes a speaker (option PMLSIF) and an external
speaker cable (option PMCC9M). External speaker cable (option PMCD1W) is
available for use with this kit to place the external speaker up to 16 feet further
away from the radio. Installation of this kit requires the option cable kit - option
PMD7Z.
1. Mount the speaker so it is directed to the operator but does not cause interfer-
ence with his vision. It also should not present a hazard in the event of an
accident. The speaker may be mounted on the lower edge of the instrument
panel, the fire wall, or above the windshield in some trucks.Use the mounting
bracket as a template for locating the mounting holes, and mount the speaker
as shown in Figure 11.
2. Install the option cable PMCD7Z if not already present.
3. Pins are supplied on the ends of the external speaker cable option PMCC9M.
Push these pins into sockets 2 and 9 of the connector housing supplied with
the option cable. Refer to Figure 8 and Table 2.
4. Plug the connector housing into P2 of the option cable.
5. Connect theplug end of the external speaker cable to the speaker. If installing
the external speaker cable option PMCDIW connect it between the speaker
and the plug end of the external speaker cable option PMCC9M.
