OPTIONAL VOICE DATA GUARD
If an extension telephone on the same line as the AFX-300 is
in use, the AFX-300 does not let your fax machine/fax modem
or data modem access the telephone line or interrupt the call
in progress.
However, to prevent an extension telephone (one not plugged
into the AFX-300) from interrupting a fax or data transmission
that is in progress on the same line as the AFX-300, you must
plug that extension phone into an optional voice data guard,
such as Radio Shack Cat. No. 43-107.
You can use a voice data guard for these situations:
When you use cordless telephones, extension tele-
phones, speed dialers, computer modems, or other tele-
phone devices on the same telephone line as your fax
machine/fax modem.
When your answering machine is too far away to easily
connect to the AFX-300’s
TAD
jack.
To install a voice data guard, follow its supplied instructions.
Note
: You do not need to use a voice data guard with the AFX-
300 if your TAD automatically stops the outgoing message
when you pick up an extension phone on the same line as the
TAD, and you connected the TAD to the AFX-300’s
TAD
jack.
