TROUBLESHOOTING
IMPORTANT:
The C50 must be serviced by trained engineers. NEVER attempt any repairs or adjustments yourself -
you could invalidate the Guarantee.
If you cannot make Calls...
Make sure your C50 is fully plugged into the telephone line socket.
Disconnect all other instruments connected to the same line as the C50 and see whether you can
make a call.
Disconnect the C50 from the telephone line and plug a different phone into the socket. Try making a
call. If this works, the line is OK.
If you are using a two-way socket adapter, remove it and plug a telephone directly into the socket, if
the call now works, the adapter may be faulty.
If you think the fault may be on the exchange line contact the service provider.
