and insert as shown 4 batteries,
type LR6, UM3 or AA-cells.
Remove the batteries if
exhausted or if they will not be
used again for a long period.
The indicator lights up on
the display, when the batteries
are nearly exhausted.
Back-up batteries for preset memory.
In order to keep the presets stored in the memory during the
time that the unit is switched off, it is necessary to insert two
additional back-up batteries.
Place these batteries size

battery compartment.
These batteries should always
be inserted, regardless of the
power supply (mains voltage or batteries).

refuse.
Hand over the old batteries to your dealer or
public collecting points when buying new ones.
AC Mains adapter (not included)
You can connect the set to the mains using a mains adapter.
Only use a mains adapter which supplies DC 6 V with the
negative pole at the centre pin of the plug (->+).
Before connecting the mains adapter
Check that the mains voltage indicated on the type plate of
the adapter matches your local mains voltage.
If the mains adapter is equipped with a voltage selector, set
this to the local voltage.
Connect the mains adapter
to the DC 6 V socket of the set
and to the wall socket.
The mains supply is switched
on.
Note:
If the DC 6 V socket is in use, the battery supply will
switch off automatically.
Note:
The unit remains connected to the mains even when it is
switched off. The unit is only fully isolated from the mains if
the mains plug is removed from the wall socket.
