Important safeguards
• The instruction manual contains
important operating and maintenance
instructions. For your safety, it is
necessary to refer the manual. Keep
the manual for use in future.
• Do not hit or drop the unit.
• Do not expose the unit to
vibration, direct sunlight, too high or
low temperature or humidity.
• If you are not going to use the unit
within a long period of time, remove the
batteries to avoid their leakage.
• Do not disassemble the unit
yourselves. Refer servicing to qualified
service personnel.
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.
