Limited component level repair may be authorized for certain class 2 C.R.C.'s. Component level repair is authorized for all class 1 C.R.C.'s, however a test bed may not be authorized depending on volume. NOTE: It may be to the C.R.C.'s advantage to repair only to the sub-assembly level. The King of Prussia production facility will repair to the component level. Parts replaced in warranty repairs are being returned to Ampex for replacement.

ORIGINATOR: J. HILL VIDEO TERMINAL-AMPEX-230,230+-----------------------FIB002 Pg001 FIB 00003 07/21/87 *** CMOS PARITY ERROR ON POWER-UP *** Catagory E - SYMPTOM SYMPTOM: "CMOS PARITY ERROR" ON POWER-UP; may operate correctly after reset and the 'ESC-V' self-test is run. CAUSE: 1. CMOS RAM's BATTERY LOW: If the voltage of the battery which powers the CMOS RAM drops below 1.1 volts, the RAM may loose its data. This can happen if the PCB is stored or shipped in conductive, anti-static bags. 2. CMOS RAM FILLED WITH RANDOM DATA: If the battery voltage has been removed from the CMOS RAM for any reason, the data in the RAM will dissapear. As power is restored, random data will fill the CMOS RAM. CORRECTIVE ACTION: 1. Class 1 and 2 CRC's: replace the defective battery - Sorbus part number YY016449. (The battery is SOLDERED IN.) 2. Enter SET-UP MODE. Press to reload the default parameters into CMOS RAM. Make whatever changes are needed and press to save those parameters in CMOS RAM.
