7. Plug the supplied adapter’s barrel plug into the
12VAC
jack, then plug the adapter into a standard AC outlet. The
POWER indicator on the front of the AFX-400 lights.
Note:
• If AC power fails, your AFX-400 automatically passes
incoming calls to its
ANSWERING MACHINE
and
PHONE
jacks, so you can answer the calls.
• The POWER indicator flashes slowly during calls.
MOUNTING ON A WALL
1. To mount the AFX-400 directly on a wall,
you need two screws (not supplied) with
heads that fit the keyhole slots on the bot-
tom of the switch. Drill two holes 3
1
/
4
inches (83 mm) apart. Then thread a
screw into each hole, letting the heads
extend about
3
/
16
inch (5 mm) from the
wall.
2. Route the modular line cords through the line guides on
the bottom of the AFX-400.
3. Place the keyhole slots over the screws and slide the
AFX-400 downward to secure it.
PREPARING AN ANSWERING MACHINE
FOR USE WITH THE AFX-400
1. Be sure your answering machine is set to answer calls i
n
less than six rings, because the AFX-400 will ring th
e
ANSWERING
MACHINE
jack only six times before routin
g
the call to the
FAX/MODEM
jack.
2. Because some fax machines do not send a fax alert tone
,
your outgoing message should give callers instructions o
n
how to send a fax (see “Receiving Faxes” on Page 8).
For example:
“Hello. Please leave your name and phone number at th
e
tone. If you want to send a fax, press #91 on your touch
-
tone phone, then press START on your fax machine.”
3. For the best performance, your outgoing message shoul
d
be 10–15 seconds long with 4 seconds of silence at th
e
beginning of the message. The silence gives the AFX-40
0
a chance to detect fax alert tones or transfer codes.
INSTALLING AN OPTIONAL VOICE DATA
GUARD
If a telephone device on the same line as the AFX-400 is i
n
use, the AFX-400 does not let your fax machine or modem ac
-
cess the line or interrupt the call.
However, to prevent an extension telephone from interruptin
g
a fax or data call in progress through the AFX-400, you mus
t
plug that extension phone into an optional voice data guard
,
such as RadioShack Cat. No. 43-107.
Note:
You do not need to use a voice data guard if your an
-
swering machine automatically stops playing the outgoin
g
message when you pick up an extension phone and you con
-
nected the answering machine to the AFX-400’s
