DESCRIPTION
This section contains the information required to
service the ORION VHF two-way FM mobile radio.
Included are disassembly procedures, alignment procedures
and troubleshooting information (see Table of Contents).
This radio is adjusted by setting personality
parameters stored in the radio computer memory. Therefore,
all radio alignment procedures require the use of a
P

Programming Interface TQ3370, and ORION PC
Programming cable TQ3377. PC Programming Software
Version 4.00 or later is also required.
This radio is designed to be serviced by
replacement of modules and/or circuit boards. As such,
there are very few serviceable component parts contained
on any of the circuit boards within the radio. Normally,
defective boards should be replaced and returned to an
Authorized Service Center. Any serviceable parts are listed
in the troubleshooting guide for the individual circuit
boards.

After the radio has been installed as described in
the Installation Manual, the following measurements should
be made by a certified electronics technician and recorded
for future reference:
TRANSMITTER
• RF power into 50 ohm resistive load
• Forward power into antenna
• Reflected power from antenna
• Carrier frequency
• Modulation deviation
RECEIVER
