POWER SOURCE
This unit is designed to operate on normal household AC power rated at
120V/60Hz. Operating this unit from any other power source may cause
damage to the unit, and such damage is not covered by your warranty.
It is also equipped with a battery back-up system for the clock that is powered
by an optional 9V 006P battery (type 6F22 or equivalent – not included).
BATTERY BACK–UP SYSTEM
The Battery Back-up System ensures the clock and alarm settings will be retained
during a power interruption or power outage (in order to preserve the battery life
the Display will not light). All clock settings will be kept in memory, however, the
clock time may require adjustment for exact accuracy once the power returns. If a
battery is not installed, the Display will blink”12:00” when the power is restored.
This will indicate that you have to reset the time and alarm settings.
BATTERY INSTALLATION
1. Open the battery compartment door on the
bottom of the cabinet and connect a 9V DC
battery to the Battery Clip located inside.
Note: The battery clip only fits one way to ensure
the correct polarity.
2. Replace the Battery Compartment Door.
IMPORTANT
: Be sure that the battery is
installed correctly. Wrong polarity may damage the unit.
3. For optimum performance, an alkaline-type battery is recommended. If the
unit is not to be used for an extended period of time, remove the battery.
An old or leaking battery can cause damage to the unit and will void the
warranty.
4. Do not try to recharge batteries that are not intended to be recharged; they
can overheat, rupture and leak. (Follow the battery manufacturer’s directions).
5. Do not dispose of batteries in fire, batteries may leak or explode.
DIMMER CONTROL
Slide the DIMMER switch on rear panel to High/Low position to control the
display brightness.
POWER FAILURE INDICATOR
If there is no battery installed in the unit or the battery installed is weak or dead,
the time and alarm settings will be lost if the power is interrupted. When the AC
power is restored the display will flash “12:00”. This indicates that the time
displayed is incorrect and needs to be reset.
IMPORTANT:
After you reset the time, be sure to reset your alarm settings as well.
