ANSWERING MACHINE USERS
WHEN USING A SEPARATE ANSWERING MACHINE
If a separate Answering Machine is to be used on your telephone line, it
is preferable to fit it direct to the PRIMARY NUMBER PORT of DUET
SWITCH 1. This will ensure that it does not incorrectly answer your
Fax Calls.
If it is to be fitted to a separate telephone socket, then the ANSWERING
MACHINE must be set to answer on more rings than your Fax Device.
DUET SWITCH 1 will ensure that your FAX DEVICE does not ever answer
incoming voice calls.
WHEN USING THE ANSWERING MACHINE
IN YOUR FAX DEVICE
If your Fax Device has an integrated Answering Machine, then you should
use our alternative DUET SWITCH 2 device.
This product can be set to connect incoming unanswered phone calls
to your FAX DEVICE after an 8 ring delay, so that it can record
messages.
ADSL USERS
DUET SWITCH 1 will not interfere with your ADSL service and your
ADSL service will not affect your DUET SWITCH device.
However, you MUST fit an ADSL FILTER between the telephone wall
socket and the Telephone Line input of DUET SWITCH, so that your
Fax Device can operate on a line with ADSL.
Do not fit the filter in any other position.
