digital transmissions. The result is a more secure conversation
with the clarity of digital sound, extended range, and minimal
interference from other cordless phones.

over 65,000 codes for the handset and base.
These features enhance your phone’s security and prevent
unauthorized calls as a result of your phone being activated
by other equipment.

Direct wall plate mounting
If you don't have a standard wall plate, you can mount your phone
directly to the wall. Before doing this, consider the following:
•Avoid electrical cables, pipes, or other items behind the mounting
location, that could cause a hazard when inserting screws into
the wall.
•Try to mount your phone within 10 - 15 feet of a working phone
jack to avoid excessive cord lengths.
•Make sure the wall material is capable of supporting the weight of
the base and handset.
•Use #10 screws (minimum length of 1-3/8 inches) with anchoring
devices for the wall material where the base unit will be placed.
1Insert two mounting screws
into the wall, (with their
appropriate anchoring device),
3-15/16 inches apart. Allow
about 3/16 of an inch between
the wall and screwheads for
mounting the phone.
