READ THIS BEFORE INSTALLATION
We have designed your TAD to con- form to federal regulations, and you can connect it to most telephone lines. However, each device that you con- nect to the phone line draws power from the line. We refer to this power draw as the device’s ringer equiva- lence number, or REN. The REN is shown on the bottom of your TAD.
If you are using more than one device on the line, add up all the RENs. If the total is more than five, your phone might not ring and your TAD might not answer. In rural areas, a total REN of three might impair ringer operation. If ringer operation is impaired, remove one of the devices from the line.
