Battery Back-Up
This clock radio is equipped with a memory holding system that can be powered
with a 9-volt battery (not included). The power failure protection circuit will not
operate unless battery is installed.
When normal household power is interrupted, or AC line cord is unplugged, the
back-up battery will power the clock radio to keep track of time and alarm settings
programmed into memory. When the battery backup functions, 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. With battery back-up, if Alarm to Radio or
Alarm to CD is activated during power interruption, Alarm to Tone will operate
instead. Wake mode will operate normally again once power is resumed.
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.

Protection against main power failures:
1. Remove battery compartment door (located on 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 9-volt battery connector plug. (6LR61 or NEDA 1604A)
3. Insert battery in the compartment and replace the compartment door.
NOTE: NOTE:
NOTE: NOTE:
NOTE: Alkaline (6LR61/NEDA 1604A) batteries are recommended. Carbon-zinc
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 are not operated) which should take care of short, nuisance-type
AC power failures. To preserve battery life, the unit should remain plugged into
an AC outlet. As the battery gets older, its voltage drops and memory may be
lost. Be sure to replace the battery periodically. Battery should be removed if
the unit will be stored for more than one month. Leaky battery can badly damage
the clock radio.
