Troubleshooting
This section contains a few tips on how to operate your phone if you encounter any problems.
■ Malfunctions
The display shows: "System overload"
At the moment no connection can be set up via the current system base. The phone is trying to set up
a better radio connection with the same or a different system base. This message appears in standby
mode only.
The display shows: "No System"
You have moved out of the coverage area; the radio connection is interrupted. Move closer to a radio
station.
Leaving the coverage area
You are outside the coverage range. You can set the phone so that you receive a warning signal if you
leave the coverage area (see Chapter "Activating range alarm and system busy beep", page 45).
Display is working, but connection is not possible
Your phone may be locked. Unlock your phone (see Chapter "Locking/unlocking the keypad", page 43).
Display brightness insufficient
The setting for the display’s brightness is unsuitable. Change the setting (see Chapter "Setting the dis-
play", page 47).
Impaired sound quality during hands-free operation
The sound quality can be affected if the volume is too loud – turn down the volume. If the sound quality
fluctuates, contact your system administrator.
Note:
For all other messages, faults and questions you may have, contact your system administrator.
