Power Source
The Addo alarm clock uses an AC power adapter (120V at 60Hz for North America, 220-240V at 50Hz for Europe/Australia). An incorrect adapter may damage the clock. A lithium battery is included to maintain time and alarm settings during power outages. To maximize battery life, keep the AC power adapter connected to an un-switched mains outlet.

Care and Maintenance
Care of Cabinets
If the cabinet becomes dusty, wipe it with a soft cloth. If it becomes smudged or dirty, clean it with a soft, slightly dampened cloth. Never allow water or any liquid to get inside the cabinet. Do not use any abrasive cleaners or cleaning pads as these will damage the finish.
Changing the Lithium Battery
The lithium backup battery (CR2032) needs replacement when the “LOW BATTERY” indicator glows amber. Otherwise, the time and alarm settings will be lost after a power outage.
- Leave the AC adapter connected to your AC outlet to retain memory while the original battery is removed.
- Unscrew the battery holder from the cabinet with a small screwdriver and insert a new CR2032 battery, observing the positive (+) polarity, before sliding the holder back into the slot. The LOW BATTERY indicator should then turn off.
Lithium Battery Precautions:
- Dispose of the old battery properly. Do not leave it lying around where a young child or pet could play with or swallow it. If the battery is swallowed, contact a physician immediately.
- The battery may explode if mistreated. Do not attempt to recharge it or disassemble it. Do not dispose of the old battery in a fire.
- The apparatus must not be exposed to dripping or splashing, and objects filled with liquids, such as vases, must not be placed on the apparatus.
