Instruction manual

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 there is a mains current failure, 
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 
from short temporary 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 re-connected 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 voltage indicated on the rating label 
corresponds the mains voltage in your home.

•  Insert the plug into the power supply.
•  The set is now working as electronic clock.
