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 servic- es 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 ET-1105’s Caller ID memory dial feature to operate, you must receive the caller’s number.

Important: Cordless phones such as this one require AC power to operate. When the AC power is off, you cannot dial out or receive incoming calls using your ET-1105. For this reason, the ET- 1105 cordless phone should not be your only telephone. To be safe, you should also have a corded phone that does not require AC power to operate so you can still make and receive calls if there is an AC power failure.

Your telephone operates on standard ra- dio 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 op- erating on similar frequencies within a certain area to unintentionally intercept your conversations and/or cause inter-

ference. This lack of privacy can occur with any cordless phone.

READ THIS BEFORE INSTALLATION

Each device that you connect to the phone line draws power from the phone line. We refer to this power draw as the device’s ringer equivalence number, or REN. The REN is on the bottom of the base.

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 (three in rural areas), your phone might not ring. If ringer operation is impaired, re- move a device from the line.

FCC STATEMENT

This telephone complies with Part 68 of FCC Rules. You must, upon request, provide the FCC registration number and the REN to your phone company. These numbers are on the bottom of the base.

Note: You must not connect your ET-

1105 to any of the following:

•coin-operated systems

•party-line systems

•most electronic key phone systems
