Power supply
Battery operation
• Insert 1 x 3 V lithium battery CR2032 (not
included) to the terminal inside the battery
compartment according to the polarity marks (+
and -). Your set will not work normally from the
battery supply, but there is now the advantage
that, in case of a mains current failure or power
outage, your clock will continue to work. The
clock display will not light up, the clock time
and alarm setting will be held in the clock
memory by the battery back-up system.
This enables you to move the set from place
to place without re-setting the clock every time.
The battery back-up system is only meant to be
used for short-term power failures. For longer
durations the battery may become exhausted or
there may be some deviation in accuracy.
• When the battery is exhausted, it should
be removed from the set to prevent leakage.
If you do not wish to take advantage of the
battery back-up system, your set will work
normally without a battery. However, if
disconnected from the mains, the clock figures
will flash when the mains are reconnected and
you must re-set the clock.
AС operation
• The appliance is for household use only.
• Before the first connecting of the appliance
check that the voltage indicated on the rating
label corresponds to the mains voltage in your
location.
• Insert the plug into the electrical outlet.
• The set is now working as an electronic
clock.

Reset
If the system does not respond or exhibits
erratic or intermittent operation, you may have
experienced an electrostatic discharge (ESD)
or a power surge that triggered the internal
microcontroller to shut down automatically. If
this occurs, simply disconnect the AC power
cord and remove the system backup battery,
wait for at least 3 minutes and then setup the
unit again as if it is a brand new unit.
