FCC INFORMATION

We have designed your System 997/998 to con-
form to federal regulations, and you can connect
it to most telephone lines. However, each Caller
ID system (and each device, such as a telephone
or answering machine) that you connect to the
telephone line draws power from the line. We re-
fer to this power draw as the system's ringer
equivalence number or REN. The REN is on the
bottom of your phone.
If you use more than one phone or other device
on the line, add up all the RENs. If the total is
more than five, your phones might not ring. In ru-
ral areas, a total REN of three might impair ringer
operation. If ringer operation is impaired, remove
one of the devices from the line.
