BACKUP FUNCTION → A
If the AC power supply is interrupted, the clock display goes
off and the alarm settings and stations that you preset are
cancelled. To back up these settings, insert a 6F22 battery in
the battery compartment on the rear of the unit.
• The backup battery is not for radio reception.
Note
The backup function lasts about 4 days. Set the clock again if
4 days have passed after a power interruption.
Replacing the battery
Replace the battery with a new one if the clock display flashes
or the alarm timer does not work properly when you connect
the AC power cord again.
Note on battery
• When you are not going to use the unit for a long period of
time, remove the battery to prevent possible electrolyte
leakage.
• To prevent the risk of electrolyte leakage or explosions,
never recharge the battery, apply heat to it, or take it apart.
If an erroneous display or operation occurs → B
When an erroneous display or operation occurs, reset the unit
pressing RESET with a thin rod.
