Troubleshooting
Leaving the radio coverage area
You will hear a warning tone if you are about to leave the area of radio coverage. Once
you have left the area the message "No System" will appear and the aerial symbol "m"
will disappear.
If during a call you move out of range completely, your call will be interrupted but the
connection will not be cleared down immediately. The system will then attempt for
around 20 s to set up a new radio connection with the same - or another - radio unit.
Only then will the connection be cleared down in the PBX.
Outside radio coverage range, you have the following M-key programming functions at
your disposal:
"Prog.", "Keys", "Mobile", "Term.", "Ring", "*Language", "Test" and "System".
Display showing but no connection
The handset may be barred (see "Barring/unbarring handset").
The Hotkey and/or Foxkey cannot be programmed
Programming may be barred (see "Barring/unbarring handset").
Unbarring the handset if password is forgotten
Ask the system manager to unbar your handset and default the password to "0000".
Special display contents
"Please wait"
This message may appear during the registration procedure. It also appears when a caller
puts the call on hold.
"Handset unknown"
The registration of the handset with the PBX system has failed. Please contact the system
manager.
"Overload"
No free resources, please wait and try again.
"System Busy"
Temporarily, calls cannot be set up via the current radio unit. The handset is trying to
establish a better radio connection with the same - or another - radio unit. The message
appears only in the idle state.
"No System"
You are out of radio coverage range; the connection with the PBX system was broken off.
"Registration"
The registration procedure on the PBX system is in progress.
"Defective" / permanent progressive ringing
Each time the handset is placed on the charging box, its parameters are checked. If a
parameter error is detected, you will hear an acoustic fault signal and the display will read
"Defective". The handset must then be sent back to the supplier for repairs/replacement.
Note
If other messages appear, ask your system manager about them.
