the backside of the unit
NOTE: Alkaline (IEC 6LR61/NEDA 1604A) batteries are recommended.
Carbon-zinc battery may be used but memory holding time will be substan-
tially reduced. Memory holding time for a fresh alkaline battery is approxi-
mately 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.
