Specifications

Possible Cause 5: Local phone company is not accurately receiving the dialing signals.
What to do: Isolate the problem. Use the telephone to make calls on different lines. Then,
make calls on different phones using the same line.
■
If you cannot make calls from one phone on all lines, follow the procedure for
“System Phone Does Not Work,” Possible Cause 2.
■
If you cannot make calls using different phones, go to Possible Cause 6.
Possible Cause 6: Too many standard devices are trying to dial simultaneously (If the
problem is on a system phone, go to Possible Cause 6.)
What to do: Stay on the line and wait for dial tone, or try to call later.
■
If you can make a call, you may want to increase the number of touch-tone receivers
by adding 206 (1 receiver) or 400 (2 receivers) modules to avoid future problems.
Call the hotline.*
■
If you wait 30 seconds and still do not hear a dial tone, go to Possible Cause 7.
Possible Cause 7: Local phone company line is faulty.
What to do: One at a time, unplug each outside line from each 206, 400, and 200 module
in the control unit. Then plug each line into a standard telephone and try to make a call.
■ If the trouble occurs on the standard phone, try another line cord; if the trouble
persists, report it to your local phone company.
■
If the trouble does not occur on the standard phone, the trouble is with your control
unit. Call the hotline.*
Calls are Answered Automatically
A call rings once, then disappears as if it were answered.
Possible Cause: An auxiliary device answers when it should not (this could occur with a
fax machine, voice messaging system, answering machine, or modem).
What to do: Be sure the device is set to answer correctly. If the device answers before it
should, adjust it to answer on a later ring. If the device should not answer calls at all, turn
off its auto-answer feature. Refer to the device’s user manual.
■
For every auxiliary device connected to your system, either set the device itself to
answer on a later ring (when the Line Ringing for the device’s extension is set to
Immediate Ring) or set the extension’s Line Ringing to Delayed Ring. For a voice
messaging system, check all of the settings associated with it. See page 2-11 for a
summary of procedures associated with the voice messaging system and Chapter 5
for complete details on each feature. If the auxiliary device no longer answers calls
automatically, the problem is solved.
■
If the problem remains, call the hotline.*
