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.

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.

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.

It must be noted that there is no guarantee of correct working of this

telephone in all circumstances when connected to a PBX. Any difficulties

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.
