Procedure V
If the green system normal LED is off, the amber system trouble LED is on, and the amber trouble indicator LED flashes a 7-blink
pattern, a telephone trouble has been detected. A telephone trouble error may be caused by:
1. Blown fuse on the digital voice module (F2 on the DX-100, F1 on the DX-200).
2. Incorrect call progress tones on telephone line.
3. Insufficient off hook voltage on telephone line.
4. Disconnect telephone line.
5. Missing or improperly installed Telephone Interface Kit integrated circuits.
6. A telephone message has gone unacknowledged for three consecutive times to one telephone number.
7. Failed circuitry on the digital voice module.
When a telephone trouble error is indicated, perform the following:
1. Check appropriate fuse on digital voice module.
2. Verify that the telephone line is connected properly.
3. Verify that the two Telephone Interface Kit integrated circuits have been installed properly.
4. Verify that all activated telephone messages have been acknowledged and are no longer playing.
5. Verify that there is voltage across the telephone line when a telephone message is selected to play.
6. Verify that the telephone provides a standard dial tone when off hook and a standard ring when dialing.
If after the above procedure is completed, the trouble condition persists, reset the digital voice announcer. Activate one telephone
message and verify that it executes correctly. If the telephone message fails to play correctly and there are no problems with the
telephone line, the telephone trouble condition is caused by failed circuitry on the digital voice module. There are no field
correctable failed circuitry problems on the digital voice module. Digital voice modules with failed circuitry shall be replaced
immediately, following the Replacement Procedure, set forth previously in this section.
Procedures W, X and Y are for systems configured with an optional Remote Microphone Station (RMS-1).
