Procedure A
Refer to Figure 14-1 on page 51.
1. Disconnect PCM from the telephone system.
2. Set dip Switch 3, 4, and 5 to ON and 1, 2, 6, and 7 to OFF on the PCMTIM.
3. Connect a telephone test set/2500-type telephone to the TEL line input of the PCMTIM.
4. Go off hook with the test set/2500-type telephone.
5a. If confirmation tone is heard and a page can be made, the PCM telephone interface is working correctly. Go to
Procedure B.
If confirmation tone is not heard, check the wiring from the telephone system or check the port that has been
provided by the telephone system to ensure you have the dip switches set appropriately for that port.
See Section 5 for proper dip switch settings.
5b. If the settings and wiring are correct and the PCM still does not page, call Technical Support.
Procedure B
Refer to Figure 14-2 on page 52.
1. Access the PCM and press [00] on the paging telephone. Simulate a page by talking into the paging telephone.
2. While talking, monitor with a test set on the PCMTBM at PA IN & RT. If voice is heard, monitor with a test set on
the PCMTBM PA OUT & RT. If the voice is heard on the PA IN & RT and not on the PA OUT & RT, ensure the
amplifier’s input level control is turned up. If the input is turned up on the amplifier but you still have no voice on
the PCMTBM PA OUT & RT terminals, the amplifier may be defective. Call Technical Support to verify this.
3. If the voice is heard on both PA IN & RT and PA OUT & RT, then monitor the PCMZPM zone outputs. Ensure
that the PCMZPM Lo/Hi Power switch is in the Hi Power mode. If you are in the Lo Power mode and using external
amplifiers per zone, voice should be heard on the zone output. If it is heard, monitor each zone amplifier’s input, then
monitor the output of each amplifier. If the amplifier has no output, check the input level control of each amplifier.
Make sure it is turned up. If you still have no output, contact Technical Support.
