8. Installation
The telephone must be sited close to one of the new modular telephone sockets.There
is no limit to the number of sockets you can have installed in your home which means
you can, if you wish, move your telephone from room to room. Unlike sockets, however,
there is a limit to the number of telephones you can operate on your exchange line.
Installing too many telephones will overload the line which could inhibit some or all of
the telephones from ringing.To avoid overloading your exchange line there is a method
of calculating the number of telephones you can use.Add all the Ringer Equivalence
Numbers (REN) together, which are marked on the base of each telephone.Numbers
differ so do check.The numbers when added together must be 4 or less. Sometimes
BT telephones are unmarked but they can generally be assumed to have a REN of
1.0.Ifindoubt,pleasecheckwithyourBTSalesOfce.TheRENvalueofyoura300
Headsetphone is 1.0.
9. Setting the Dialling and Recall Mode
The settings must be carried out BEFORE connecting the telephone to the telephone
socket. Please note that batteries are not supplied with the unit.
Remove the battery compartment cover on the underside of the base by removing the
screw and sliding back the cover. N.B.The telephone must be disconnected from the line
before removing the battery cover. Fit 2 size M (or equivalent) leakproof alkaline batteries
observing correct polarities.The batteries support information in the memories.
Note: If the Auto Redial function does not operate, you need to replace the batteries.
Two preset switches will be found situated underneath the memory card inlay.These are
the DIAL MODE SELECTOR SWITCH and RECALL MODE SELECTOR SWITCH and
should be set as follows:
9.1 THE DIAL MODE SELECTOR SWITCH
BT are replacing all local exchanges with new ‘TONE’ dialling digital systems.They will
give improved clarity and reliability and with ‘Touch Tone’ signalling telephones, instant
connection of calls over digital exchanges and a host of advanced features. However
some telephone exchanges in the U.K. still operate on the PULSE dialling system.
Your a300 Headsetphone series telephone allows you to operate on either system
and the DIAL MODE SELECTOR SWITCH should be set to the dialling mode required
by your exchange. Set the switch to the PULSE position for pulse dialling or to the
TONE position for tone dialling. If in doubt about the correct dialling mode used by your
exchange, please consult your Network Operator.

9
9.2 THE RECALL MODE SELECTOR SWITCH
If you are connected to a TONE dialling exchange, set the switch to the TBR (Timed
Break Recall) position to enable you access certain Network Services.
If you are connected to a PULSE dialling exchange, set the switch to the ELR(Earth
Loop) position as recall has no function on direct lines connected to such exchanges.
(This will avoid the possibility of cutting off your call should the recall button be pressed
accidentally.)
If you are connected to a PABX, set the switch according to the requirements of your
particular PABX. If in doubt, consult your PABX Instructions or your PABX maintainer.
Havinginstalledthebatteriesandsettheswitches,retthebatterycompartmentcover
ensuring that it is screwed fully into place.
9.3 NETWORK SERVICES
BT are replacing all local exchanges with new digital systems. They will give improved
clarity and reliability and with Tone signalling telephones, instant connection of calls over
digital exchanges and a host of advanced features.
If you are on a digital exchange, you can instruct it to ring you back with the cost of your
call. Or you can use it to set up reminder calls, where the exchange rings you at a time
you specify.
You can even instruct the exchange to divert your incoming calls to another number, or
deal with two calls at once, or set up a 3-way call.
These services are called Network Services: to use them you need a tone signalling
telephone.Tondoutifyouareonadigitalexchange,orwhenitwillbeprovided,
contactyourlocalBTofce.
Your a300 Headsetphone provides tone signalling when the Dial Mode selector switch is
set to the (TONE) position and the Recall Mode selector switch is in the TBR position.
If your system requires PULSE dialling, you can change to TONE dialling once the call
has been established by pressing the TONE button.This enables you to access special
services such as Banking etc. which require access digits to be transmitted in TONE
mode. It is important to wait for the call to be established before keying in the access
digits. On completion of the call, the telephone will revert to PULSE dialling.
*TouchTone is a trademark of BT in the U.K.
If you are connected to a PABX, set the switch according to the requirements of your
particular PABX. If in doubt, consult your PABX Instructions or your PABX maintainer.

14.10 DIALLING NUMBERS FROM MEMORY
To dial a number from memory, lift handset or press Speaker or Headset
button, await dial tone and press button corresponding to memory location
require ensuring that the correct memory ‘shift’ is selected.
Sometimes it may be necessary to combine the information from 2
memories or to combine memory dialling with manual dialling. In these
cases, simply press the 2 memory buttons in sequence or press the desired
memory button followed by manual dialling of the remainder of the number.
These combinations are often carried out when alternative carriers are used.
14.11 PAUSE FACILITY
With some PABX’s, it is necessary after dialling an outside line access
digit (often 9) to wait for new dial tone before dialling the outside number.
If the PAUSE button is pressed after the access digit has been dialled, the
number may be dialled immediately without waiting for new dial tone as the
telephone will introduce the required pause in the dialling sequence. In some
cases it may be necessary to introduce a second pause, but do not enter
more than 2 pauses or unsatisfactory operation may result.

15
14.12 MIXED DEAL MODE OPERATION
STORING MIXED DIAL MODE NUMBERS
If you are connected to an exchange requiring PULSE dialling and you wish
to route your calls via an alternative carrier (if available), it is necessary to
dial an ACCESS code in PULSE mode followed by a pause and then an
AUTHORISATION code in TONE mode. Since the telephone numbers of all
calls to be re-routed via the alternative carrier will have to be preceded by
the same access and authorisation codes, it is convenient to store them in a
memory location.
For example, if your access code is 123 and your authorisation code is
4567890 and you wish to store the combined codes in memory location
M1, you would proceed as follows:-
1. Seize the line in any mode.
2. Press STORE button once.
3. Key in 123
4. Press TONE button (this changes the dialling mode to tone)
5. Press PAUSE button to introduce a pause, Note that it may be necessity
to introduce a second pause but do not enter more than 2 or incorrect
operation may result.
6. Key in 4567890
7. Press M1 button
8. Release the line.
During the storing process, the number will be displayed in the LCD.
To dial a number via the alternative carrier, lift handset or press Speaker
button, await dial tone, press M1 button and then dial the telephone number
you are calling. Alternatively, press the M1 button followed by another
memory button if the called number is stored in a memory location.
14.13 RECALL BUTTON
This is generally only used when the telephone is connected to a PABX
(Private Automatic Branch Exchange) and gives access to features provided
by that exchange. However, RECALL is becoming a feature on the new
digital exchanges to give access to new services such as some of BT’s
Network Services.
For full information on the use of the RECALL button, please consult your
PABX instructions or your Network Operator providing the services.
For setting the correct RECALL mode, please refer to section under
‘INSTALLATION’.
12.10 DIALLING NUMBERS FROM MEMORY
To dial a number from memory, lift handset or press Speaker or Headset button, await
dial tone and press button corresponding to memory location require ensuring that the
correct memory ‘shift' is selected.
Sometimes it may be necessary to combine the information from 2 memories or to
combine memory dialling with manual dialling. In these cases, simply press the 2 memory
buttons in sequence or press the desired memory button followed by manual dialling of
the remainder of the number.These combinations are often carried out when alternative
carriers are used.
12.11 PAUSE FACILITY
With some PABX’s, it is necessary after dialling an outside line access digit (often 9) to
wait for new dial tone before dialling the outside number. If the PAUSE button is pressed
after the access digit has been dialled, the number may be dialled immediately without
waiting for new dial tone as the telephone will introduce the required pause in the

your calls via an alternative carrier (if available), it is necessary to dial an ACCESS code
in PULSE mode followed by a pause and then an AUTHORISATION code in TONE
mode. Since the telephone numbers of all calls to be re-routed via the alternative carrier
will have to be preceded by the same access and authorisation codes, it is convenient to
store them in a memory location.
For example, if your access code is 123 and your authorisation code is 4567890 and you
wish to store the combined codes in memory location M1, you would proceed as
follows:-
1. Seize the line in any mode.
2. Press STORE button once.
3. Key in 123
4. Press TONE button (this changes the dialling mode to tone)
5. Press PAUSE button to introduce a pause, Note that it may be necessity to
introduce a second pause but do not enter more than 2 or incorrect operation may
result.
6. Key in 4567890
7. Press M1 button
8. Release the line.
During the storing process, the number will be displayed in the LCD.
To dial a number via the alternative carrier, lift handset or press Speaker button, await
dial tone, press M1 button and then dial the telephone number you are calling.
Alternatively, press the M1 button followed by another memory button if the called
number is stored in a memory location.

15. OPERATING PROCEDURE FOR PBX CONNECTION
The a300 Headsetphone is suitable for connection to a PABX which returns secondary
proceed indication.
15.1 PBX RECALL
When connected to a PBX, the telephone will send a Recall Signal to the
exchange when the RECALL button is pressed.This a300 Headsetphone
provides either TIMED LINE BREAK RECALL or EARTH RECALL. Consult
your PBX supplier or maintainer to ascertain which is compatible with your
PBX. Having established which you require select either ELR (Earth Recall)
or TBR (Timed Line Break Recall) using the ELR/TBR switch.
NB. Like the mute key the Recall key is a ‘hard switches’ not a ‘soft press’
key.This means that it will only depress slightly, and will remain depressed
until released.
15.2 PABX PAUSE FACILITY
On PABX systems which provide secondary proceed indication you must
wait for the secondary proceed dial tone after dialling the initial access
digit(s), normally 9 for an outside line. For correct operation of the Memory
facilities it is therefore necessary to store a Pause after the access digit to
ensure correct dialling. Pressing the LNR key automatically inserts a 3.6
second pause in the dialling sequence.
NB: Do not enter more than 3 consecutive pauses. Failure to comply with
this may result in unsatisfactory operation and will invalidate the approval.
15.3 MESSAGE WAITING OPERATION
On 4 wire systems set the switch to 2/5 to enable message waiting on
compatible systems. For 6 wire systems set the switches to 1/6. Only one
message waiting telephone may be connected to an extension. If more
than one message waiting telephone is connected to a line, the system may
interpret this as an off hook condition.
15.4 GENERAL USE
It must be noted that there is no guarantee of correct working of this
telephoneinallcircumstanceswhenconnectedtoaPBX.Anydifculties
should be referred to the telephone supplier.
This telephone is approved for connection to most PBX’s. The supplier of
this telephone should be consulted for an up to date list of PBX’s with which
this telephone is compatible.
