Preventive Maintenance CHECK VISUAL INDICATORS AND DEVICE STATUS TABLE (CMC-800) REGULARLY TO DETERMINE SYSTEM OPERATING STATUS. DO NOT OBSTRUCT AIR FLOW AT TOP OF SYSTEM CABINET OR POWER SUPPLY. KEEP FOREIGN PARTICLES AND LIQUIDS FROM ENTERING VENTILATION HOLES. KEEP ALL GROUNDING, POWER, AND INTERFACE CABLES DRESSED AND FREE FOR EASY ACCESS. CLEAN HEADS ON PMP MICROCASSETTE TAPE DRIVE WITH DENATURED ALCOHOL PRIOR TO LOADING OR SAVING OPERATIONS. I/O DEVICE ERROR CAN BE CAUSED BY DIRTY TAPE HEADS. AVOID STATIC ELECTRICITY DISCHARGES WHILE HANDLING PCB CARDS. MICROPROCESSORS, PROM, RAM, AND OTHER MICROCIRCUITS CAN BE DAMAGED IF FOLLOWING PROCEDURES ARE NOT IMPLEMENTED: - GROUND YOURSELF TO CABINET WITH ANTI-STATIC WRIST STRAP DEVICE BEFORE INSERTING OR REMOVING CARDS. - SPRAY SYSTEM CABINET AREA AND CARD STORAGE SURFACES WITH ANTI-STATIC SPRAY. - NEVER TOUCH GOLD-PLATED CONNECTORS OR COMPONENTS. - USE EJECTOR TABS WHEN REMOVING CARDS FROM SLOTS AND HANDLE CARDS BY EDGES ONLY. - ELIMINATE STATIC PRODUCING MATERIALS (CELLOPHONE, STYROFOAM, ETC.) FROM CABINET AREA. - STORE UNUSED CARDS IN ANTI-STATIC BAGS. - TURN POWER OFF WHEN INSTALLING COMMON CONTROL OR RGEN CARDS. IF BACKUP BATTERY CANNOT BE RECHARGED OR REPLACED IMMEDIATELY, SAVE ODDB TO TAPE OR FLOPPY DISKETTE. 3.3
