Safety Instructions
• Only use the charger plug supplied. Do not use other chargers, as this may
damage the battery cells.
• Only insert rechargeable batteries of the same type. Never use ordinary,
non-rechargeable batteries. Insert rechargeable batteries so they connect to
the right poles (indicated in the battery compartment of the handset).
• Do not touch the charger and plug contacts with sharp or metal objects.
• The operation of some medical devices may be affected.
• The handset may cause an unpleasant buzzing sound in hearing aids.
• Do not place the basic unit in a damp room or at a distance of less than
1.5 m away from a water source. Keep water away from the handset.
• Do not use the telephone in environments where there is a risk of
explosions.
• Dispose of the batteries and maintain the telephone in an environment-friend-
ly manner.
• As this telephone cannot be used in case of a power cut, you should use a
mains-independent telephone for emergency calls, e.g. a mobile phone.
Cleaning
