•
If you are not sure of the cadence, disable Function 16 and try to call the
unit. If the unit answers, ringing to the unit is nonstandard and the unit
must be operated with Function 16 disabled.
2. Unit answers but does not return answer tone
A. If the green LED is not flashing:
•
If the unit answers and the LED is not flashing, the M-106E may need
repair. Since this involves hazardous voltage, ask a qualified technician to
unplug the power cable from the wall and verify that there is 12 VAC
±
10% at the wall receptacle. If not, the problem is an open circuit breaker or
faulty building wiring. (If the wall receptacle is on a switched outlet,
ensure that the switch is on.)
•
Plug the power cable into the wall receptacle without the unit connected to
it.
•
Verify that there is a minimum of 12 VAC at the power cable connector.
Reconnect the unit.
•
If the green LED still does not flash, refer to the Return Procedures in
Chapter 7.
B. If the green LED is flashing:
•
Check the telephone cable to the IN side. Call the unit. If the IN LED does
not light, disconnect the line from the IN side and connect it to an analog
telephone.
•
Call the telephone number for the IN side. When the telephone rings,
answer the call and check that the talk path is acceptable.
•
If the talk path is present and acceptable, the problem may be with the
unit. If, however, the talk path is not satisfactory, the problem is with the
telephone line. Reconnect the incoming line to the M-106E.
•
Press the front panel switch to PROGRAM until the green light flashes
quickly.
•
Call the unit, wait for the M-106E to answer (the IN LED lights) and listen
for three beeps. If you do not hear three beeps, the M-106E is defective.
Refer to the Return Procedures in Chapter 7.
•
If you hear three beeps, verify that answer tone (Function 2) and password
(Function 15) options are enabled. (Answer tone is not returned if the
password option is disabled.)
•
If both features are enabled, set the answer tone (Function 3) to the loudest
setting, level 3.
