Important safeguards

• The instruction manual contains important operating and maintenance instructions. For your safety, it is necessary to refer to the manual. Keep the manual for future use.
• Do not hit or drop the unit.

• Do not disassemble the unit yourselves.
  Refer servicing to qualified service personnel.

All the illustrations in this manual are schematic images, which may differ from actual objects.

Power supply

Battery operation

• Insert 3 x 1.5V lithium AAA batteries to the terminals 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 light up for 10 seconds after pressing any button. 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.

• 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.
