Your telephone has built-in protection circuits to reduce the
risk of damage from surges in telephone line and power line
current. These protection circuits meet or exceed the FCC
requirements. However, lightning striking the telephone or
power lines can damage your telephone.
Lightning damage is not common. Nevertheless, if you live
in an area that has severe electrical storms, we suggest that
you unplug your phone when storms approach to reduce the
possibility of damage.

You can use your telephone as a desk phone, mount it on a
standard wall plate, or mount it directly on a wall. Select a
location that is near the telephone line jack(s).
To take full advantage of many of the phone’s features you
must have three telephone lines with separate phone
numbers. If you have only one phone line, you can order
two additional lines from your local phone company.
Your phone comes with one long and one short two-line
modular cords, and one long and one short single-line
modular cords. The two-line cord has four pins inside the
jack. The single-line cord has two pins inside the jack.
Your telephone connects directly to a modular telephone
line jack. If your telephone wiring does not have a modular
jack, you can update the wiring yourself using jacks and
adapters (available at your local RadioShack store), or have
the telephone company update the wiring for you. You must
use compatible modular jacks that are compliant with Part
68 of
FCC Rules.
.
The USOC number of the single-line jack to be installed is
RJ11C (or RJ11W for a wall plate jack). The USOC number
for a two-line jack is RJ14C (or RJ14W for a wall plate).

You must use a Class 2
power source that
supplies 9V AC and
delivers at least 500 mA.
Its plug must fit the phones’s AC
9V jack. The supplied adapter
meets these specifications. Using
an adapter that does not meet
these specifications could damage
the phone or the adapter.
Always connect the AC adapter to
the phone before you connect it to
AC power. When you finish,
disconnect the adapter from AC
power before you disconnect it
from the phone.
