ˆImportant Information

READ THIS BEFORE INSTALLATION

Your phone is ETL listed to UL standards and meets all applicable FCC standards.

We have designed your telephone 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 REN is on the bottom of your telephone’s base.

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.

IMPORTANT CALLER ID

INFORMATION

To use the phone’s Caller ID and Call Waiting features, you must be in an area where Caller ID and Call Waiting services are available and you must subscribe to the services.

Where Caller ID is offered, one or more of the following options are generally available:

caller’s number only

caller’s name only

caller’s name and number

For the phone’s Caller ID memory dial feature to operate, you must receive the caller’s number.

Your telephone operates on standard radio frequencies as allocated by the FCC. Even though the access protection code prevents unauthorized use of your phone line, it is possible for other radio units operating on similar frequencies within a certain area to unintentionally intercept your conversations and/or cause interference. This lack of privacy can occur with any cordless phone.
