TROUBLESHOOTING AUDIO
If satisfactory operation can not be achieved, you should fault find your
problem with the wiring or telephones downstream of our unit by connecting
them to our unit 1 device at a time.
If satisfactory operation cannot be achieved, you should disconnect the
telephone cable from the DOOR PHONE port of your
DS3
unit and
temporarily run NEW CAT5 cable from the
DS3
to your DOOR PHONE.
Alternatively, you can remove the Door Phone from its normal position and
move it closer to the
DS3
unit so that you can connect it using a temporary
new CAT5 cable. Please ensure this temporary test cable is no less than 20
feet away from your
DS3
unit in order to prevent Audio Feedback.
If satisfactory operation can be achieved, you should fault find your problem
in the wiring leading to the DOOR PHONE unit.
If satisfactory operation cannot be achieved, you should disconnect the
telephone line input to the LINE IN port of your
DS3
unit. (Note: with the
telephone line disconnected, audio communication can be achieved, but
DTMF operation will not work).
If satisfactory operation can be achieved, you should fault find your problem
caused by the incoming telephone line. If you are using ADSL, ensure that
you are using a single high quality ADSL filter. These devices are available
from your Dealer.
If your problem is still unresolved, please call (07) 5596 5128 to report the
above results and arrange for further advise or repair.
