All batteries should be replaced at the same time. Mixing old and new bat-
teries may cause the batteries to leak which will result in damage to the
device.
Batteries must not be short-circuited, taken apart or thrown into fire. There is
a danger of explosion!
Do not expose the batteries to any extreme conditions. Do not place them on
radiators and do not expose them to direct solar radiation.
Do not recharge normal, non-rechargeable batteries; danger of explosion!
Only charge rechargeable batteries intended for this purpose and use suit-
able chargers.
Always observe the correct polarity (plus/+ and minus/-) when inserting the
batteries.
Remove drained batteries from the device as soon as possible to prevent leak-
ing. Use only batteries of the same type and with the same charge condition.
Use only leak-protected batteries.
• Open the battery compartment on the rear of the device.
• Insert four new type 1.5 V Mignon batteries (AA) in the battery compartment in the
correct polarity. The correct polarity is indicated in the battery compartment.
• Close the battery compartment again.
• If the device no longer works or if the display contrast deteriorates, the batteries are
discharged and must be replaced.
b) Mains Connection
Only the enclosed plug-in AC/DC adapter must be used for mains power sup-
ply.
If the device is not used for an extended period (e.g. before starting extended
travels), pull the AC/DC adapter from the socket and remove the batteries.
The mains socket to which the AC/DC adapter is connected must be close
to the device and easily accessible to quickly separate the device from the
mains voltage in case of an error.
