APPENDIX A A - 21
Multi-line connections (PBX)
(For Australia and New Zealand only)
Most offices use a central telephone system. While it is often
relatively simple to connect the machine to a key system or a PBX
(Private Branch Exchange), we suggest that you contact the
company that installed your telephone system and ask them to
connect the machine for you. It is advisable to have a separate line
for the machine.
If the machine is to be connected to a multi-line system, ask your
installer to connect the unit to the last line on the system. This
prevents the unit from being activated each time a telephone call is
received.
If you are installing the machine to work with a PBX
1
It is not guaranteed that the unit will operate properly under all
circumstances with a PBX. Any cases of difficulty should be
reported first to the company that handles your PBX.
2
If all incoming calls will be answered by a switchboard operator,
it is recommended that the Receive Mode be set to
Manual . All
incoming calls should initially be regarded as telephone calls.
Custom features on your phone line
If you have Voice Mail, Call Waiting, Call Waiting/Caller ID,
RingMaster, an answering service, an alarm system EFTPOS,
PC/FAX modem or other custom feature on one phone line it may
create a problem with the operation of your machine. (See Custom
features on a single line. on page 10-11.)
