Digital Spread Spectrum Technology utilizes a “wider frequency band” vs. a “single narrow band”
used in standard digital transmissions. The 2.4 GHz frequency range was recently released to commercial
communications. The result is a more secure conversation with the clarity of digital sound, extended
range, and minimal interference from other cordless phones.
Random Code™ digital security automatically selects one of approx. 65,000 codes for the handset
and base.
These features enhance your phone’s security and also prevent unauthorized calls as a result of your
phone being activated by other equipment.

devices suitable for the wall material where the base unit will be
placed.

anchoring device), 3-15/16 inches apart. Allow about 3/16 of an inch
between the wall and screwheads for mounting the phone.
