BALANCE POT ADJUSTMENT
Your DOOR PHONE is preset at the factory for maximum performance.
Our sophisticated circuitry is designed to measure the background noise present
at your site and then apply maximum gain.
In almost all cases you SHOULD NOT NEED TO MAKE ANY ADJUSTMENTS.
If you are using Two Door Phones, it is possible that you will need to adjust the
POT of one or both Door Phones to suit your specific site conditions.
For Models DP2-DP5, a balance POT is provided in case you experience one of
the following:
Audio is distorted.
Audio (speech) can only be heard in 1 direction.
Should you encounter one of these problems, you will need to make slow careful
adjustments in one direction or the other until speech can be heard in both
directions and without distortion.
The balance POT is located on the back of DOOR PHONE under a small 3mm
removable black plastic plug. It should be adjusted using a small flat blade
screwdriver.
IMPORTANT NOTES
1)
You will require TWO PEOPLE to adjust your Door Phone Pot.
2)
Wait 10 seconds after answering before adjusting the Pot.
3)
DO NOT use a telephone in close proximity to the door phone, as
feedback interference will affect the Balance Pot settings.
4)
The Balance POT does not increase volume.
5)
Moving it when unnecessary may cause deterioration in audio quality.
