Before wall mounting run the cable through the hole that you have prepared. Then
mark two mounting holes on the wall, through the amplifier front. Remove the
amplifier and drill the mounting holes. Use the plugs and screws included in the
delivery. Use a drill of the diameter of 6 mm. After fastening, cover the screws with
the blanks supplied.
Use the supplied connectors to connect the amplifier to the intercom and power
supply. The A connector is connected to the amplifier four-wire cable. Insert a special
intercom-connecting cable supplied with the amplifier and 12 V power supply outlets
to the B connector. Connect the special cable to the intercom and connect the power
supply to the mains. You can place the mated A and B connectors into the 2N IP
intercom cover. The connectors help you connect stripped cables. Open the
connector by pushing a thin screwdriver onto the white spots at its front and close the
connector by sliding the movable part through a side gap.
Finally, test the amplifier function using a suitable receiver for hearing impaired
persons or magnetic field communication tester. No other settings are required.
