Installation options
The telephone base comes with the mounting bracket set for tabletop use.
If you want to mount your telephone on a wall, swivel the mounting bracket
down so the telephone can connect with a standard dual-stud telephone wall
mounting plate. If you do not have this mounting plate, you can purchase
one from many hardware or consumer electronics retailers. You might need a
professional to install the mounting plate.
Tabletop to wall mount installation
To install the telephone base in the wall mount position, make sure that you
first unplug all cords connected to the telephone base.
1. Press in as the arrows indicate. The bracket will detach from the telephone
base. Swivel it down into wall mount position, making sure it clicks into place.
