The installation of the Door Keeper motor has been done beforehand. If you are replacing an existing player, be sure to turn off the old player and remove the batteries.
Insert the 3 batteries respecting the polarity in the Badge Reader. Press the central button of Door Keeper for 3s to access Pairing mode. The motor LED should slowly flash WHITE. On the reader, press the PADLOCK key for 3s. The reader thus flashes GREEN. The 3 beeps will confirm the correct execution of the procedure. Don't forget to create codes or pair badges.
