READ THIS BEFORE INSTALLATION

We have designed your control unit to conform to federal regula-
tions, and you can connect it to most telephone lines. It has a ring-
er equivalence number, or REN, of 0.5B. If you are using 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 rural ar-
eas, a total REN of three might impair ringer operation. If ringer op-
eration is impaired, remove the device from the line.
