Install the machine in a dust-free location
away from direct sunlight.

–

Place the machine near an electrical outlet
that is easily accessible.

–

Do not plug the machine into a power source
shared by items that produce electric noise
(e.g., air conditioner, etc.).

–

The design of this machine requires electrical
grounding, and is thus supplied with a three-
wire grounded power cord.  For your safety as
well as that of others who may operate the
machine, please do not attempt to alter the
power cord by modifying the grounding prong.

The Line jack is for connecting the machine to
a standard telephone line.  To avoid damage
to telephone systems and/or the machine, do
not plug the machine into anything other than
a standard RJ-11C jack.

The TEL jacks on the back of the machine are
only suitable for two-wire devices.  Some
standard telephones may not respond to
incoming signals when connected to an
extension socket.

The machine may not necessarily provide the
effective transfer of a call from a telephone
connected to the same line.

–

The operation of this machine on the same
line as that of a telephone or other device
equipped with an audible warning device or
automatic call detector may result in bell
vibration (sporadic ringing) or false tripping of
the call detector.  If such a problem occurs,
the user is requested to NOT contact the
telephone company.

–

Adjustment of the electrical/electronic compo-
nents in the machine requires an authorized
service technician.  Do not attempt to make
adjustments yourself. Any alterations made by
an individual other than an authorized service
technician may be cause for nullification of the
product warranty.
