batteries specified.

CAUTION

: Danger of explosion if battery is 

incorrectly replaced. Replace only with the 
same or equivalent type.

• 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 batteries 
may become exhausted or there may be 
some deviation in accuracy.

The time will start to flash on the display.

• When the batteries are exhausted, they

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 batteries. However, if 
disconnected from the mains, the clock 
figures will flash when the mains are 
reconnected and you must re-set the clock.
