We have designed your Digital Answering System to conform to
federal regulations, and you can connect it to most telephone
lines. However, each device 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. The

answer. If ringer operation is impaired, remove a device from
the line.
FCC STATEMENT
Your system complies with Part 68 of the
FCC Rules

Note:
You must not connect your system to:
coin-operated systems
party-line systems
most electronic key telephone systems
