DESCRIPTION | INITIAL MEASUREMENTS |
This section contains the information required to service the ORION VHF Dual Bandwidth
This radio is adjusted by setting personality parameters stored in the radio's computer memory. Therefore, all radio alignment procedures require the use of a Personal Computer (IBM PC or equivalent), along with a Programming Interface TQ3370, and an 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.
