Battery Back-Up Operation EN This clock radio is equipped with a memory holding system that can be powered with a 9V battery (not included). The power failure protection circuit will not operate unless battery is installed. When normal household power is inter- rupted, or AC line cord is unplugged, the battery will power the clock radio to keep track of time and alarm settings pro- grammed into memory. When the battery backup functions, the digital display will not be backlighted, however, the function of alarm still occurs during the power in- terruption 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. Install battery as follows: 1. Remove battery compartment door (located at the bottom of the radio) by applying thumb pressure to area indicated on battery door and then lift the door out and off the cabinet. 2. Connect a 9V battery to the connector plug. 3. Insert battery in the compartment and replace the compartment door. 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. Note: Alkaline (NEDA 1604A / IEC 6LR61) battery is recommended. Carbon Zinc (NEDA 1604 / IEC 6F22) battery may be used but memory holding time will be substantially reduced. Memory holding time for a fresh alkaline battery is approximately 8 hours (if radio or alarm is not operated), which should take care of short, nuisance-type AC power failures. To preserve battery life, the radio should remain plugged into an AC outlet. As batteries get older, their voltage drops and memory may be lost. Be sure to replace the battery periodically. Battery should be removed if the radio will be stored for more than one month. Leaky batteries may badly damage the clock radio. 2 RP3710 EN 3 3/3/03, 4:29 PM
