Place the compatible cordless handset on the charging poles; the Charge LED illuminates during charging (full charge in 11 hours). For cordless integration, register the handset to a compatible telephone base by placing it in the cradle—automatic registration occurs with 3 beeps confirmation. Deregistration: On idle handset, press *331734# then HOLD for confirmation tone. To register to another base, place on new base for automatic process. Desktop: Place on flat surface. Ensure installation height under 2 meters.
Place handset on C5012; Charge LED should turn on. For full system check with compatible base: Ensure power and telephone line cords are secure. Press TALK/FLASH on handset for dial tone, then OFF/CANCEL to hang up. Verify registration by placing handset on base (3 beeps). Test incoming call: Handset rings, message waiting LED flashes on base/handset. For cordless range, move handset within effective range and confirm no interference. Adjust RF transmission power if out of range. If no dial tone, unplug/replug power for 15 seconds to synchronize (up to 1 minute). In hospitality, test speed dial keys (e.g., CONCIERGE) for programmed numbers.
Program speed dial on compatible handset: Press *234636# then MUTE to enter mode (up to 32 digits). Deregistration: Idle handset, press *331734# then HOLD. No direct programming on C5012; relies on handset/base. For hospitality, program speed dials for services. Battery replacement: Slide cover, align and insert Model No. 523450AR1000, secure cover.
