— Equipment cannot be used on
public coin phone service provided
by your telephone company.
Connection to party line service is
subject to state tariffs. (Contact the
state public utility commission,
public service commission or
corporation commission for
information.)
Signaling method
This unit's push-key dial pad allows it
to signal in tones (DTMF). It can
complete calls to local and long-
distance lines and can also complete
long-distance calls using computer
telephone systems such as MCI™ or
SPRINT™.
MCI is a trademark of MCI.
SPRINT is a trademark of United
Telecommunications.
Ringer Equivalence Number
The FCC Registration label (on bottom
of telephone) includes a Ringer
Equivalence Number (REN), which is
used to determine the number of
devices you may connect to your
telephone line. A high total REN may
prevent telephones from ringing in
response to an incoming call and may
make placing calls difficult. In most
areas, a total REN of 5 should permit
normal telephone operation. To
determine the total REN allowed on
your telephone line, consult your local
telephone company.
Hearing aids
This telephone is compatible with
hearing aids equipped with an
appropriate telecoil option.
