Battery Back-Up Operation EN This clock radio is equipped with a memory holding system that can be powered with 2 "AAA" batteries (not included). The power failure protection circuit will not operate unless battery is installed. When normal household power is interrupted, or the AC line cord is unplugged, the battery will power the clock radio to keep track of time and alarm settings programmed into memory. When the battery backup functions, the digital display will not light, however, the function of alarm still occurs during the power interruption if the 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. Install battery as follow: 1. Unlock the battery compartment door (located at the bottom of the radio) by sliding the tab away from the door. 2. Remove the battery compartment door. 3. Insert 2 "AAA" batteries. 4. Replace the compartment door and slide the tab to lock battery compartment. Power Failure Indicator When 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 readjust the time and alarm settings. 2
