Battery operation

• Insert 1 x 3.0 V lithium battery CR2032

(

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.
