Maintenance and Service

If the CM1000 fails to operate and no front panel indicators are illuminated, the internal nickel metal hydride battery may be discharged. Use the supplied AC adapter to power the unit and recharge the battery. If the failure persists while using the AC adapter, call Sunrise for service.

If the internal battery fails to recharge, verify that the AC adapter is actually sending power to the CM1000. Plug the AC adapter into the CE4000 RECHARGE input and then connect the AC adapter to the 115VAC source. Turn the CM1000 on to test the battery condition and then back off. If the internal battery fails to recharge, but the AC adapter delivers power to the CM1000, the battery may be deeply discharged or damaged. A deep discharge requires a longer charge time. If the battery is not restored to normal operation by an eight-hour recharge (unit off), call Sunrise for service.

Firmware Upgrades

Firmware upgrades may be downloaded from the Sunrise web site at www.sunrisetelecom.com. Complete instructions are provided at the web site.

CompactFlash Card Replacement

The CE4000 utilizes a removable CompactFlash card for future expansions and/or firmware upgrades.

Before removing the CompactFlash card, be sure that the CM1000 is off.

Set the unit on its side on a flat surface with the plug-in module slot facing upward and the keypad facing you. The memory card slot is located on the side of the unit just to the right of the keypad and is protected by a small cover held in place by two Phillips head screws. Remove the two Phillips head screws and the protective cover. The memory card will be visible in the slot. A small rectangular shaped button to right of the memory card will also be visible. Press this button to eject the memory card from its slot and then pull the card out of the slot (a pair of tweezers or needle nose pliers may be helpful).
