L BI-39175A 2 DESCRIPTION This section co ntains the inform ation required to service th e ORION VHF Du al Bandwidth tw o-w ay FM radio. Inclu ded are disassembly procedures, align men t procedures, and trou bleshooting inform ation (see Table of Contents).
LBI-39175 A 3 MAINTENANCE PREVENTIVE MAINTENANCE To ensure h igh operating eff iciency , and to preven t mech anical and electrical f ailures from interru pting sy stem operations, routin e checks sh ould be m ade of all m echanical an d electrical equipm ent at regular interv als.
L BI-39175A 4 DISASSEMBLY PROCEDURE To Remove the Unit from the Mounting Bracket 1. Remove Microphone, Power, and Accessory/Remote Control Cables, as required. 2. Remove the lock screws at the side of the radio unit, using a No. 20 TORX driver. 3.
LBI-39175 A 5 3. Disengage the four captive screw s on the rear half (also know n as th e Rem ote Interface Adapter, or RIA) of the Control Head. Slide the tw o halves apart, usin g care to avoid dam agi ng the black "O- Ring" moisture gasket attached to the RIA.

LBI-39175 A 9 TRACKING DATA The radio p ersonality contains certain information bytes know n as Tracking Data, which allow the radio computer to calibrate transmitter power, modulation deviation, and squelch threshold .
L BI-39175A 10 SETTING TRACKING DATA Normally , Tracking Data is set at the factor y , and need no t be re-loaded. Ho wever, the f ollowing repair situatio ns require re-loading some or all of the Tracking Data: SITUATION NEW TRACKING DATA Replace PA module RF Power, Squelch (Check: Re-load if necessary.
LBI-39175 A 11 TRANSMITTER ALIGNMENT The Transmitter consists of sy nthesizer, exciter, and pow er am plifier. These have been calibrated at the factory so the radio com puter autom atically adjusts RF pow er and m odulat ion devi ation, bas ed upon Tracking Data.
L BI-39175A 12 w ire board runs to separate f rom the board. Check for shorts and solder bridges before applying power. Failure to solder the transistor leads as directed may resul t in th e gen eration of RF loops that could dam age th e transistor or m ay cause low pow er outpu t.
LBI-39175 A 13 SQUELCH ADJUSTMENT Squelch th reshol d has been set at th e factory to 8 dB SINAD. A djust me nt of the threshol d requires chang ing the Tracking Data.
L BI-39175A 14 SERVICEABLE PARTS Control Unit - Switch Circuit CDF-368B/M No serviceable parts. Control Unit - Panel Control CMC-638 No serviceable parts.
LBI-39175 A 15 DIAGNOSTIC PROCEDURES This product can be easily measu red for m aintenance using a Communications Service M onitor, o f w hich several m odels are available. A ty pical test conf iguration for th e OR ION product is s how n in Figu re 5.
L BI-39175A 16 ADDITIONAL TOOLS REQUIRED • RF Pow er Attenu ator (30 dB, 150 w att, for trans mitters w ith RF pow er bey ond the capabilities of a Service Monitor) • Digital Voltmeter • Oscilloscope (optional) TRANSMITTER SYMPTOM DIAGNOSTIC PROCEDURE No RF power output.
LBI-39175 A 17 RECEIVER SYMPTOM DIAGNOSTIC PROCEDURE Low RF sensitivity. a. Pro gram a Conventional System w ith frequencies given in T ables 2 and 3. Use "EDACS3" PC Programming utility. b. Unscrew the PA m odule from th e TXRX module. Disconnect the coaxial cable P2 from J401 on the Sy nthesizer PWB.
L BI-39175A 18 CONTROL UNIT SYMPTOM DIAGNOSTIC PROCEDURE Radio dead at power-on (display dark and no lighted indicators) a. Check the battery con nections an d the Red lead A + fuse on the pow er cable.
LBI-39175 A 19 GENERAL SYMPTOM DIAGNOSTIC PROCEDURE Any hardware malfunction PWB substitution is a valid technique for service and re pair of the ORION product, since there are only a few circuit boards in the product: 1. RF Power Amplifier 2. Logic/IF/Audio 3.
L BI-39175A 20 message ERR = xxxx where xxx is the error code and the message is one of the messages listed below Figure 6 - Error Message/Code Display FATAL ERRORS NON-FATAL ERRORS ERROR MESSAGE DESC.
LBI-39175 A 21 ROM Fatal Systems Errors ROM fatal errors may be corrected by cycling the radio power (turn it off then on). When the power cycle does not correct the problem the radio must be serviced. ERROR NAME MESSAGE CODE DESCRIPTION FATAL_SYS_TRAP HARDWARE 0 Fatal system error trap number.
L BI-39175A 22 Operational Software Fatal System Errors ERROR NAME MESSAGE CODE DESCRIPTION RADC_PITD_ERROR TRACKING 200 Personality tracking data error. Re-program the tracking data. RADC_PIHW_ERROR PERSDATA 201 Personality hardware data error. Re-program the personality.
LBI-39175 A 23 Radio Programming Errors Programming errors are divided into three categories: 1. Protocol Errors - These are errors produced by the low level communication routines. 2. Radio Errors - These are errors that are returned from the radio ROM or operating software.
