Battery replacement

The clock radio has two battery compartments. The

batteries in the small compartment on the rear side of

the LCD panel are responsible for displaying the time

and date, the ones in the bigger compartment on the

bottom side for radio operation.

So depending on whether the time display is not

showing, or the radio doesn’t work replace the

batteries in the corresponding compartment.

And this is how to do it:

Changing the batteries for time display

Unscrew the screw fixing the battery compartment

cover using a small screw driver for recessed-head

screws.

Remove the battery compartment cover and take

out the batteries (if necessary).

Insert two unused batteries (1,5V, Typ V10GA, LR54,

not enclosed) according to the layout plan shown in

the battery compartment. When doing so, you have

to comply exactly with the correct polarity, otherwise

the clock will not function and may get damaged.

Changing the batteries for radio operation

Open the battery compartment on the bottom side

of the unit.

Remove the battery compartment cover and take

out the batteries (if necessary).

Insert two unused batteries (1,5V, size “AAA”, not

enclosed) according to the layout plan shown in

the battery compartment. When doing so, you

have to comply exactly with the correct polarity,

otherwise the radio will not function and may get

damaged.

To ensure a longer and more useful economic life,

you should use Alkaline batteries.

Close the respective battery compartment.

Batteries must not be disposed of in domestic

waste. Please hand in used batteries at the

proper collection point or at the place where

you have bought the new ones. Never throw

batteries into fire.
