1. No communication between handsets.
Improper connection of the "C" terminal ("C" stands for "call", not "common"). Connect the "C" terminal of a phone to the designated number terminal on another phone. (e.g. "C" of phone #1 connects to "1" terminal of other phones; "C" terminal of phone #2 connects to "2" terminal of all other phones, etc.)
Refer to TD-H Instructions.
2. Feedback while paging.
Overhead speakers are located too close to the master initiating the page. Turn down the amplifier until feedback goes away, move the speaker, or obtain an RY-SP local speaker cut-out relay and install according to the instructions provided.
3. No paging.
Check for proper paging adapter (TD-H requires either the PD-1 or PD-2 adapter, or the use of a PG-C series amplifier). If a PG-C amp is used, check the setting of switches 7&8 (For the PD-1; 7 is on, 8 is off. For PD-2; 7 is off, 8 is on).
Refer to PD-1 Instructions, PD-2 Instructions or PG-C Instructions.
4. System with PG-C series amplifier, music and paging are fine but there is no paging pre-tone at all.
The #6 dip-switch on the PG-C amplifier must be "on" for any pre-tone to be heard. Refer to #5.
5. Music and paging are fine but paging pre-tone is too loud or too quiet.
Pre-tone volume is adjusted separately from paging / music volume. If the system includes a PG-C amplifier, the pre-tone control is located with the Bass/Treble controls. If the system is using a PD-1 or PD-2, the pre-tone volume control is located on the bottom of the paging adapter.
6. Door station calls in, but there is no communication.
A DE-UR door station adapter is required for each door station being connected. Only IF/IE door stations may be used with the TD-H system. Check for proper connection of the "C" terminal between the DE-UR and the TD-H handsets.
Refer to the DE-UR Instructions.
7. Door station calls in and communicates, but the door release does not work.
For the door release to function, communication must first be established with the door station. Then press the "page" button in the handset. Door strike must have its own power source, and be connected to the EL, EL terminals in the DE-UR.
Refer to the DE-UR Instructions.
8. Door station volume is too low.
Only IE/IF door stations may be used with the TD-H system. Check for proper connection of the door station to the DE-UR and also the "C" terminal between the DE-UR and the TD-H handsets. The volume to the door station is inherently low, due to the fact that the door station contains a speaker and microphone. The DE-UR can be modified to raise the volume at the door station, but the resulting volume may still be lower than desired. Contact Technical Support for information regarding this modification.
