Calling Black Box - Black Box ASD-4 Manual

• Lifting the receiver of the phone device connected to the TAD or
PHONE port and hanging it up.
• Answering a call at any phone on the ASD-4's line before the call is routed
to the FAX or MODEM port.
• Placing an outbound call from any phone on the ASD-4's line.
You can also turn the Automatic Ring Reduction feature OFF. See
Section 5.3.1.
6. My fax just came on line when I was right in the middle of a conversation.
On very rare occasions, two people, just by talking, can match the two tones
that are generated when you press a single key on a tone-dialing phone. It is
possible for this phenomenon to fool the ASD-4 into thinking it has heard the
FAX or MODEM Access Code, so that the ASD-4 transfers the call to the FAX
or MODEM port. To virtually assure that this will never happen again, change
these access codes from numbers with repeating digits (and tones), like the
factory-preset [1] [1] and [2] [2], to numbers with two or more digits whose
tones are completely different. Both of a digit's tones will be different from
those of another digit if the two digits' keys are in different rows and different
columns on a phone's keypad (for example, [1] and [5], or [4] and [9], or
[3] and [7]).
7. The ASD-4 isn't saving my programming changes.
You must press the [*] key twice after your final program entry: once to mark
the end of that entry, then again to tell the ASD-4 to save your changes. See
Section 5.1.

6.2 Calling Black Box

If your ASD-4 seems to be malfunctioning, do not attempt to alter or repair it;
contact Black Box for technical support.
Before you do so, make a record of the history of the problem. Black Box
will be able to provide more efficient and accurate assistance if you have a
complete description, including:
• the nature and duration of the problem,
• when the problem occurs,
• the components involved in the problem, and
• any particular application that, when used, appears to create the problem
or make it worse.
