▪ Why will the unit not ring the handset?

Answer:

Try re-coding the handset and transmitter per instructions.
Check push button wiring to the transmitter with multi-meter.
Check power cable distance from power adaptor to transmitter is less than 4 meters

▪ The user can hear interference through the handset

Answer:

Check cable distance between the speech unit and transmitter. Shorten this if possible.
Check cable used between the speech unit and transmitter is screened CAT5.
Check that the screen of the CAT5 is connected to the ground in the transmitter per wiring instructions.

▪ Keypad code is not operating the gate or door

Answer:

Check if the corresponding relay indicator light comes on.

If it does, then the fault is either a power problem with excessive cable run, or wiring.
If the relay can be heard clicking, then it is a wiring problem.
If a click cannot be heard, then it is likely a power problem.
If the light does not activate and the keypad emits an error tone, then the issue is likely a programming error.

▪ Why will the handset not re-code

Answer:

Try the process again. If it still does not work, delete the code from the transmitter. To delete code, press the code button for 3 seconds and release. Then press it 7 times after which a tone should be heard. Then press another 7 times. Now try re-coding the handset again as per the procedure.

▪ Handset work beside the intercom but not in the building

Answer:

Check that the power cable to the transmitter is within guidelines and is heavy enough gauge. Insufficient power cabling will reduce transmission power!
Check that there are not excessive objects blocking the signal, like large dense shrubs, vehicles, foil lined wall insulation etc.
Try to achieve line of sight between both devices.

▪ Why is there no speech in either direction?

Answer:

Check CAT5 wiring between speech panel and transmitter.
Disconnect, re-strip cables and re-connect again.

▪ Handset won't charge properly

Solution:

Try replacing both batteries with equivalent Ni-Mh batteries firstly. It is possible to have a dead cell in a battery which can prevent both batteries from charging.
Check for contamination or grease on the charging pins at the base of the handset (gently scratch with screwdriver or wire wool).
