2. Adjust the sensitivity of the Doorphone's microphone, if required (see
page 11).
3. Remove the required pop-outs on the back of the Unit and slide the
wires through the back of the Unit. Connect to the Doorphone's
terminal block.
4. Secure the Unit to the wall using the appropriate screws (not
supplied).
5. Re-connect the front panel to the back unit using the supplied 10 mm
( / ") M3 threaded screws.
To flush-mount the Panasonic KX-T7775 Doorphone:
1. Separate the Doorphone Unit into two halves. Discard the rear
section of the Unit.
2. Adjust the sensitivity of the Doorphone's microphone, if required (see
page 11).
3. Attach the gasket to the rear of the interface bracket, as shown in
Figure 8. (The gasket side faces the wall.)
4. Gang-box only: Attach the interface bracket to the gang-box using
screws (not supplied) (see Figure 9).
Recessed only: Attach the interface bracket to the wall using the
appropriate screws (this is dependent on the surface structure) (see
Figure 10). Refer to the mounting template, on page 15, for drilling
positions.
