Figure 4 - Typical Installation (Remote Mount Shown)
It is suggested that the radio be installed by one of the many authorized
General Electric Service Stations located throughout the United States.
These experienced service stations can provide a proper radio
installation and make any final adjustments that may be needed.
WARNING
•Vehicular Electronics-Electronic fuel injection systems, electronic
anti-skid braking systems, electronic cruise control systems, 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 a radio is transmitting. If the vehicle
contains such equipment, consult the dealer to determine if such
electronic equipment will perform normally when the radio is
transmitting.
•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.

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-off space
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.
INSTALLATION
RUNNING CABLES
To assure the feasibility of the planned cable routings, it is suggested
that the cables be run before mounting the radio. The Orion mobile
radio may be installed as a Front Mount, Remote Mount or Cassette
Mount. The type of mount, the application and the options to be
installed should be considered when planning the cable runs. Figures 5-
12 provide Interconnection Diagrams for typical installations. Figures
5-12 should be referenced throughout this manual and throughout the
installation.
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. Coil any surplus cables and secure them out of the
way. 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 firewall, trunk wall and
the channels above or beneath doors. Channels through door and
window columns that are convenient for running cables may also be
used, unless rigid or flexible conduit is to be installed for cable runs.

CAUTION
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 and 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.
Control Cable (Remote Mount Only)
The Control Cable is used to connect the Control Unit (through the RIA)
to the Radio Transceiver in remote applications. Plug P2, at one end,
connects to the Remote Control Cable Connector (RCCC) which is
mounted on the back of the RIA. The Ignition Sense wire is also part of
P2. The other end of the Control Cable (P1) connects to the ORCC
which is mounted on the back of the radio. P1 of the EURO Control
Cable also contains the Power Cable leads. See Figures 20-23.
CONTROL UNIT MOUNTING (REMOTE
APPLICATIONS ONLY)
1. Using the bracket as a template, mark and drill the mounting holes.
Be sure to leave enough room at the rear of the control unit for the
cable connector. Refer to Figure 24 for control unit mounting
bracket installation.
2. Secure the mounting bracket using the four No. 10 x 3/4 self-
tapping screws supplied (use No. 10 x 1-1/2 if needed.).
3. Secure the control unit to the bracket with the two 1/4-20 x 5/8 hex
head screws and lock washers provided.

Ignition Sense (All Applications)
NOTE
•
The radio as shipped from the factory has the "ignition sense"
feature disabled. As such the radio will be powered ON or OFF as
determined by the front panel ON/OFF/VOLUME control only
(assuming A+ and A- are connected). If it is desired to enable the
"ignition sense" feature, open top cover of radio and remove shield
from logic PWB. Slide switch SW601 from position 3-2 to 1-2.
Replace shield and top cover. Be sure to apply correct torque to
screws holding top cover in place. See Maintenance Manual.
•
The "Accessory" point should drop to ZERO volts when cranking
the engine and return to +12 volts after the engine is started. If a
point is chosen that drops to a voltage between zero and +12 volts,
the radio may execute a power-up cycle several times during start
up. It is recommended that the terminal be measured with a
voltmeter to be sure it shuts off (goes to zero volts) during the
cranking of the engine.
The fuse holder must be attached to the yellow sense lead along with the
ring terminal as follows:
1. Cut the yellow sense lead approximately 6-12" from the end that
will be connected to the power source.
2. Strip the insulation from each end of the short lead and from the
end of the long lead at least 3/8".
3. Insert the stripped end of the long lead and one end of the short lead
into the narrow end of each fuse holder half.
4. Crimp the leads in the fuse holder halves with a crimping tool.
5. Insert the 3 amp fuse into one end of the fuse holder and join the
two fuse holder halves firmly together.
6. Attach the ring terminal to the end of the short lead and connect
this lead to the ignition "ON" sense point [preferably an
"Accessory" point (in the vehicle fuse panel) that is switched on
when the vehicle ignition switch is in the ACCESSORY and RUN
positions].
