1. The lithium backup battery needs replacement when the LOW BATTERY

indicator ﬂashes, otherwise, the time and alarm settings will be lost/reset

after a power outage.

2. Leave the AC adapter connected to your AC outlet to retain memory while the

original battery is removed.

3. Unscrew the battery holder from the cabinet with a small screwdriver and insert

a new battery with the same CR2032 (3V) or equivalent type into the holder the

same way, observing the positive (+) polarity before sliding the holder back into

the slot. The LOW BATTERY indicator should then be Off.

Note: If pairing unsuccessful, all previously paired Bluetooth devices around

should be disconnected or turned off ﬁrst, in order to avoid making any auto

reconnection between them. Then, set this unit to Bluetooth mode, and tap

the Bluetooth switch on your phone/device off and back on again to refresh/

search any nearby "ER100" for pairing.

If you want to disconnect this unit from your Bluetooth enabled device after

pairing successful, press and hold the “BT PAIR” button for 2 sec. To

reconnect this unit, just select "ER100" again from the Available/Paired

device list.
