OPERATING PROCEDURE FOR PBX CONNECTION
The NR200Hp businessphone is suitable for connection to a pAbx which returns
secondary proceed indication.
12.1
PBX RECAll
When connected to a pbx, the telephone will send a Recall Signal to
the exchange when the RECALL button is pressed. This NR200Hp
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.
12.2
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. 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.
12.3
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.
