Set up the potentiometer P1 in a position, ensuring optimal acoustic conditions.
It is recommended to check all installed uniphones. In case, when in any of them
acoustic feedback appears, it should be eliminated by adjusting potentiometer of
microphone amplification in the uniphone. In case, when more such uniphones
have been found, correction of potentiometers P1 and P2 positions should be
introduced.

placing the receiver. In entry phone 8 different calling signals are available which
may be individually programmed in each apartment. Calling signal is changed by
pressing electro-catch button in the uniphone.
An installing specialist may change calling volume by pressing a lever under the
