Preparing to use your 
Berkshire 100

INITIAL CHECK
Our telephones are checked, tested and leave us 
in perfect condition. If yours is damaged, please 
return it to your supplier with proof of purchase, for 
a replacement. 

TELEPHONE NUMBER LABEL
The telephone incorporates a label underneath the 
handset for recording frequently used telephone 
numbers. To remove the plastic cover, operate the 
release clip with your thumb nail and hinge upward.

CONNECTION
The Berkshire 100 telephone can be connected 
either to a Direct Exchange Line, or as an extension 
to a compatible company exchange (PABX).

HANDSET CORD
This cord will require connection between the 
telephone and handset. Take any end of the handset 
cord, locate the port marked ‘HANDSET’ on the left 
hand side of the Berkshire 100 and simply push to 
locate. Connect the other end to the base of the 
handset to complete.

LINECORD
The Berkshire 100 arrives with a linecord for 
connection to a standard BS6312 BT-socket. The 
rear of the telephone has a port marked ‘LINE’, plug 
your selected linecord into this port fi rst and the 
other end to your telephone line termination point. 
RJ45 & RJ11 linecords are available as an option, 
ask your supplier for details. 

WALL AND DESK MOUNTING KITS
A wall or desk mounting kit is available as an option,  
please contact your supplier for further information.

Receiving calls

Incoming calls will be announced by the audible 
ringer and fl ashing LED. To answer the call, simply 
lift the handset.

Making calls 

Pick up the handset and listen for dial tone
Dial the required telephone number

(Note: making external calls from a company 
exchange (PABX) requires the number to be prefi xed 
by an access digit, normally ‘9’)

Features and Facilities

TRANSFER KEY (RECALL)
Berkshire 100 telephones are provided with a 
‘TRANSFER’ key, required by modern public and 
private exchanges, in order to gain access to 
various features such as ‘transferring a call’. For 
this, the 2 position selector switch at the rear of the 
telephone, must be set to the ‘T’ (Time Break Recall) 
or ‘E’ (Earth Leg Recall) position, to suit your system 
requirements.

REDIAL KEY 
If you wish to redial the last number you dialled, you 
can do so by lifting the handset and pressing the 
‘REDIAL’ button.

MUTE KEY
The microphone in the handset can be turned off 
(mute) in order for you to refer to a colleague without 
your caller hearing you.

Pressing the ‘MUTE’ button turns off the 
microphone and gives visual LED indication within 
the ‘MUTE’ button. 
Pressing the ‘MUTE’ button again turns the 
microphone back on and the LED is turned off.


HANDSET VOLUME KEY
The handset volume on your Berkshire 100 can be 
increased by a fi xed level by pressing the ‘VOLUME’ 
button.  This is particularly useful on a poor line, or 
if a caller has a quiet voice.  To return to normal 
volume, press the ‘VOLUME’ button a second time.

Note: The handset volume is NOT set back to the 
lower level when the handset is replaced.

RINGER VOLUME AND PITCH
The ringer volume and pitch are selected via the 
keypad using the following sequence:

HEARING AID COMPATIBILITY
For hearing aid users, an inductive coupler has 
been installed in the handset of the Berkshire 100, 
to improve audible effi ciency.

Help

If the telephone appears to be faulty when fi rst 
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.

ALL OPERATIONS SEEM SATISFACTORY 
EXCEPT THE TRANSFER BUTTON

Change the recall selector switch setting (T/E). 
If the transfer operation is now satisfactory, the 
problem is resolved.

ALL OPERATIONS SEEM SATISFACTORY 
EXCEPT THE VOLUME BUTTON

Disconnect the linecord from the telephone socket 
for at least 10 minutes.

Re-connect the linecord to the telephone socket.  
Ensure that you raise and replace the handset 
within 1 minute of re-connecting the line cord to 
the telephone socket.

For help with call divert and call pickup please 
contact your Telecom Team/Provider as this will 
vary depending upon what switchboard you are 
connected to.
