Before you begin

This clock radio is equipped with a memory holding system that can be powered with 9V battery (not included). The power failure protection circuit will not operate unless battery is installed.

When normal household power is interrupted, or AC cord is unplugged, the battery will power the clock radio to keep track of time and alarm settings programmed into the memory. When the battery backup functions, the digital display will not light, however, the function of alarm still occurs during the power interruption if remaining battery power is adequate. Normal operation will resume after AC power is restored so you will not have to reset the time or the alarm.

Power Failure Indicator

When the AC power is interrupted (disconnected) for a short period of time, both time and alarm settings will change (unless optional battery is installed). After AC power is restored (reconnected), the Digital Display will blink to indicate that power was interrupted and you should re-adjust the time and alarm settings.
