Faults and self-help with
troubleshooting

telephone. In some cases, problems can be
resolved by briefly interrupting the power
supply to the base station (unplug the
power supply unit and then plug it in again)
or removing the battery cells from the hand-
set and reinserting them. The following
information is designed to help you with
specific problems.

be resolved if you take the complete device
(base station, handset and connection
cable) to the place of purchase.
