Calibration procedure
Once all the components are connected, perform the calibration procedure so that the
intercom operates optimally according to the sound insulation of the barrier and the
ambient noise of the location.
This procedure requires two people, one on the inside of the barrier and the other on the
outside.
Important note:
For proper operation of the equipment is important to calibrate it to suit
the sound insulation of the barrier.
