HELP
If the telephone appears to be faulty when first connected, a few simple
checks may help to identify some possible problems, as listed below:
NO DIAL TONE
• Check that the telephone plug is fully inserted in the socket.
• If it is, try connecting the telephone into another socket, if available. If dial
tone is now heard, the original socket is faulty.
• Alternatively, try connecting another telephone into your socket. If this
telephone gives dial tone, then your new telephone is probably faulty.
RINGER DOES NOT SOUND
• Check that the telephone plug is fully inserted in the socket.
• If it is, check that the ringer volume is not set to Off.
For help with call divert and call pickup etc. please contact your Telecoms
Team (IT) or Service Provider as this will vary depending on what
switchboard you’re connected to and is NOT a function of the Berkshire 420.
Further concerns may also be addressed by calling our Technical Support
Department on 0330 333 8259, our main switchboard on 0330 333 8250 or

COMPLIANCE NOTES

the supplier of your Berkshire 420 to confirm compatibility with your PABX
Whilst the Berkshire 420 is compliant as an extension to a compatible PABX
system, it cannot be guaranteed to operate under all possible conditions of
connection. Any case of difficulty should be referred, in the first instance, to
the supplier of your telephone.
