Before you Begin
Plugging in for power:
- Connect the power cord to a convenient wall outlet.
- Once connected with power, the clock flashes. Refer to the Clock section for instructions on properly setting the Clock.
Battery back-up operation:
- This clock is equipped with a timekeeping system that can be powered with a 9-volt alkaline battery (not included). The power failure protection circuit will not operate unless battery is installed.
- When normal household power is interrupted, the battery will power the clock 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 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.
To install the battery:
- Remove battery compartment door (located at the back of the clock) by applying thumb pressure to the tab on battery door and then lift the door out and off the cabinet.
- Connect a 9-volt alkaline battery (not included) to the connector plug.
- Replace the compartment door.
Power failure indicator: If you have not installed the 9-volt alkaline battery in the product, or the battery runs out while power is interrupted, all the settings (clock and alarm) will be lost. After AC power is restored, the Digital Display will flash to indicate that power was interrupted and you should readjust the time settings.
NOTE: It is recommended to replace the battery at least once per year even if no power failures have occurred.
NOTE: Alkaline (NEDA 1604A/IEC 6LR61) type battery is 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 alarm is 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. A leaky battery can badly damage unit.
