6-11
What to do:
If calls could be made without trouble before, find out if someone
changed the Outgoing Call Restriction (#401) for the extension.
■ If someone changed the Outgoing Call Restriction setting, verify that the
change was an appropriate one.
■ If no one changed the Outgoing Call Restriction setting, go to Possible
Cause 4.
Possible Cause 4:
Station Lock was used to lock the extension.
What to do:
Use Station Unlock from extension 10 to unlock the extension.
■ If you can make a call, the problem is solved.
■ If the extension was not locked, go to Possible Cause 5.
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 7.)
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), 400 (2 receivers), or 308EC (6
receivers) modules to avoid future problems. Call the hotline (see page
6-1). 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, 308EC, 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 (see page 6-1).
