Important Information
5
If you use more than one phone or other
device on the line, add up all of the RENs. If
the total is more than five (three in rural
areas), your telephones might not ring. If
ringer operation is impaired, remove a
device from the line.
In the unlikely event that your phone causes
problems on the phone line, the phone
company can temporarily discontinue your
service. If this happens, the phone company
attempts to notify you in advance. If
advance notice is not practical, the phone
company notifies you as soon as possible
and advises you of your right to file a
complaint with the FCC.
Also, the phone company can make
changes to its lines, equipment, operations,
or procedures that could affect the operation
of this phone. The telephone company
notifies you of these changes in advance, so
you can take the necessary steps to prevent
interruption of your telephone service.
This device complies with part 15 of the

S URGE P ROTECTION
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.
