power failure Maintenance
POWER FAILURE_________________________
As soon as a power failure occurs, the clock radio
will switch off. As soon as the power supply
returns Du 'uD flashes, indicating that you must
reset the correct time on the clock.
Battery Back-up System
A 9 volt. E-block Type 6F22/PP3 battery or equivalent
{not supplied) can be fitted into the battery compart­
ment. It will, in the event of a power failure, provide
sufficient power to maintain the Clock/Alarm,
memory. The display will not illuminate but when the
power is restored the time and alarm time will have
been retained and so will not require resetting. The
use of an alkaline battery is recommended. The nor­
mal life of a new battery is about one year. For clarity:
Alarm, radio and display do not work on battery.
Before inserting the battery, connect the power
plug to the mains.
Place the battery in the compartment on the
underside of the clock radio (see diagram).
Replace the battery once year. The service of the
battery depends on how often and for how long
the power supply fails. This varies from a region to
another.
Note: Always reset the time after a power-failure.
MAINTENANCE
• If you do not intend to use the clock radio for a
long period, it is better to remove the power
plug horn the mains. In addition to this, it is
advisable to remove the battery from the clock
