We have designed your answering
system to conform to federal
regulations, and you can connect it to
most telephone lines. However, each
answering system (and each device,
such as a telephone or answering
machine) that you connect to the
telephone line draws power from the
telephone line. We refer to this power
draw as the device's ringer equivalence
number, or REN on the bottom of your
answering system.
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
