DUoFONE 93T Auto Dialer
(430-0297) Troubleshooting Faxback Doc. # 19578
If you have trouble with your AUTO DIALER, first review the operating
instructions to be sure you understand them completely. If the AUTO
Dialer still isn't working properly, this section of the manual will
probably give you the answer.
If you hear a tone when you try to store a number
Did you use a code name of 2 to 6 digits?
Did you FREE the memory when you first installed the AUTO DIALER?
Are you trying to use a code name that is already stored in the
memory?
If you hear a tone when you dial a stored number
Is there a code name entry "pointing" to another name, such as a
alternate long-distance number? If so it must be pointing to a
3-digit that is already stored.
If the AUTO DIALER has memory problems
Did you FREE the memory when you first installed the AUTO DIALER?
Are you pressing the buttons too quickly when storing a number? Try
entering the numbers more slowly.
During the STORE command, are you pausing at least 2 seconds after
dialing the code name and pressing [#]?
If the AUTO DIALER sometimes has trouble redialing the last number dialed
First slow down your dialing a little, because short tones are harder
to detect. If this doesn't help, the central phone office might be
sending a "tone blanking signal" while you are dialing the last digit
of some local numbers. You can hear this when you press the last
digit; you hear the tone, then no tone, and then the tone again. This
is heard by the AUTO DIALER as two tones, and can cause misdialing.
For these numbers, you need to press the last digit a short enough
time to eliminate the "second" tone.
The problem is:
Too short a tone is difficult for the AUTO DIALER to detect.
If you are unable to adjust your dialing to correct this problem,
there is still a solution. After coming off hook, dial [#] followed
by the number you want to Auto Dial. Press the switch hook, and then
use the redial command, as usual.
If the AUTO DIALER starts dialing when you answer the phone (Only for one
AUTO DIALER used with one multi-line phone)
If you use one AUTO DIALER for all the lines of your multi-line phone,
it is remotely possible that it will start dialing when you answer the
phone. This can only happen within the first few seconds after you
press your phones line selector buttons, if your phone was on a line
that wasn't being used.
It occurs if your voice generates a tone similar to certain touch-
tones. It helps to answer the phone in a moderate voice, rather than
a loud one. If the AUTO DIALER does start dialing, briefly pressing
the switch hook should restore the connection.
If you leave your phone on hook for 4 seconds after pressing the line-
selector button, you will never have this problem.
If the AUTO DIALER ignores commands
You probably connected to a system that has its own special commands.
These interfere with the AUTO DIALER commands. Try canceling all
the system's special commands, and see if this helps. If it does,
experiment to find the commands that interfere with the AUTO DIALER.
You might have a system with a "privacy feature" that prevents people
in your office from listening to an ongoing call. Some privacy
feature models interfere with the AUTO DIALER. Try disabling the
feature to see if it is the problem.
The rest of the TROUBLESHOOTING requires the adjustment of parts
inside the AUTO DIALER or having the phone company change your wiring.
If you are not comfortable making the adjustments yourself, take the
unit to Radio Shack and be prepared to describe the problem. Our
service people will make the necessary adjustments for you.
If the AUTO DIALER has trouble dialing
There are 2 things that might keep the AUTO DIALER from dialing.
Symptom 1 is that the AUTO DIALER signals that it's heard a ring before it
actually detects one when dialing a busy number.
Symptom 2 is when it doesn't seem to notice a busy or ring signal when it
occurs.
In either situation, adjust trimmer 2 inside the case.
First remove the cover from the case. Find the slots on the bottom of the
case, and pry off the cover with a screwdriver or a coin.
Adjusting the trimmer control
For Symptom 1: Move the control knob counterclockwise one-eighth of a
turn. Try the AUTO DIALER again and see if dialing
improves. If not, keep turning the knob counter-clockwise
1/8 turn until the situation improves.
For Symptom 2: First turn Trimmer 2 clockwise all the way. At this point
there are 3 possible solutions.
(1) The AUTO DIALER works fine.
(2) Symptom 1 occurs. Then turn Trimmer 2 counter-
clockwise 1/16 turn at a time until Symptom 1 goes
away.
(3) Symptom 2 persists. Find Trimmer 1, on the board.
Turn Trimmer 1 counter-clockwise 1/8 turn at a time
until the AUTO DIALER is unable to dial a stored
number. Then turn it clockwise 1/16 turn until it
dials properly. If Symptom 2 still persists, there's
nothing more you can try. If you now experience
Symptom 1 see point 2 above.
If the AUTO DIALER pauses too long before dialing a number
If the AUTO DIALER pauses 5 seconds or more before dialing, it is not
hearing a dial tone. If you hear a dial tone, move Trimmer 2 clockwise
until dialing is consistently correct. (See above). If you don't hear a
dial tone, check that Trimmer 1 is fully counter-clockwise. (See above.)
If it is counter-clockwise and the problem persists, a technician should
change R6 to 100 ohms. Then adjust Trimmer 1 so that it is as far clock-
wise as possible, with the AUTO DIALER consistently dialing correctly.
If the AUTO DIALER pauses at the wrong time when it's dialing
This problem is very rare. But since the AUTO DIALER has been programmed
to look for extra dial tones, it may think that it's hearing them if you
have a "noisy" phone line. In this case, every time it thinks it has
heard a dial tone, it will wait 5 seconds before it continues to dial.
If this is a continuing problem, and your phone does not have extra dial
tones, go to the "Jumper Adjustment - Dial Tone" section on page 27and/or
below, and follow the instructions to override the "Extra Dial Tone
Detector."
This problem and its solution have absolutely no relationship to dial tone
detection when dialing Alternate Long Distance numbers.
If the AUTO DIALER doesn't respond to computer tones
The AUTO DIALER listens for a computer tone that lasts at least 3 seconds,
to distinguish the tone from a shorter tone associated with a ring. Some
computers generate short tones. For these computers, moving a jumper can
tell the AUTO DIALER to employ Time-lapsed Override. Then it assumes the
computer tone occurred at 16 seconds elapse after the AUTO DIALER finishes
dialing the computers. Go to the "Jumper Adjustment-16 Second Time-out"
section starting on page 27, (see below) to make this adjustment.
If you use the AUTO DIALER for many phones on one long line, and there is
a hum when it is dialing.
Another symptom of the same problem is the AUTO DIALER's mistaking a busy
signal for a ring, or dialing an Alternate Long Distance number within 4
seconds of dialing the local computer's number, without waiting for the
computer tone. Then locate jumper J1. Jumper J1 is in the front left
corner of the board, next to the two black phone jacks and the white box.
It is labeled "J1" on the board.
The jumper normally connects pins 1 and 2, the two pins closest to the
front of the board (the side that the jacks face). Remove the jumper from
pins 1 and 2, and put it on pins 2 and 3.
You will still hear a hum, but the AUTO DIALER may now work properly.
Jumper Adjustment
To adjust a jumper, first remove the cover from your AUTO DIALER. Just
find the slot on the bottom of the case, and pry off the cover with a
screwdriver or coin.
Find the jumper
There are two jumpers The Extra Tone Jumper determines whether the AUTO
DIALER looks for extra tones, and the 16-Second Time-out Jumper determines
whether it waits until it hears a tone, or continues to dial after 16
seconds elapse whether it hears a tone or not.
Extra Tone Jumper 16-Second Time-out
1 2 3 4 5 6
Looking from edge of Board
To move a jumper, simply pull it off its pins and push it onto 2 other
pins.
Extra Tone Jumper Adjustment
The Extra Tone Jumper goes over either pins 1 and 2, or 2 and 3. The unit
comes with the jumper over in 2 and 3.
Pins 1 and 2 - If the AUTO DIALER should not - look for extra dial tones
Pins 2 and 3 - If the AUTO DIALER should look for extra dial tones
(normal)
16-Second Time-out Jumper Adjustment
The Time-out Jumper Adjustment goes over either pins 4 and 5, or 5 and 6.
The unit comes with the jumper over pins 4 and 5.
Pins 4 and 5 - If the AUTO DIALER should wait for the computer tone
(normal)
Pins 5 and 6 - If the AUTO DIALER should continue dialing after 16
seconds.
If you do not hear tones in your tone phone's ear piece after starting a
command
After you press the [#] or [*] button, the AUTO DIALER sends power to your
phone so that more tones can be generated. If you don't hear tones after
the [#] or [*] is pressed, somewhere in your phone system two wires are
backwards. (These wires are called Tip and Ring.) Here we assume that
your phone worked before the AUTO DIALER was installed.
Situation 1: If the Series Jack was installed by the phone company.
The jack was probably installed incorrectly. Ask the phone
company to install it correctly, checking the cost, if any.
Situation 2: If you use the AUTO DIALER with one single-line phone, and
do not use the Series Jack.
Your phone attaches to a wall jack through a cord. First
remove the cover of this jack, and locate two screws.
Screw 1 connects to at least two wires, including at least
one Red wire. Screw 2 connects to at least two wires,
including at least one Green wire.
Remove all the wires from under Screw 1, and use a piece of
tape or rubber band to keep them together. Do the same for
all the wires under Screw 2. Now fasten to Screw 1 all the
wires that were under Screw 2. Fasten to Screw 2 all the
wires that were under Screw 1.
