With Dual Keypads

FEATURES
Your Radio Shack ET-910 900 MHz Digital Cordless Speakerphone With Dual Keypads uses advanced digital cordless telephone technology to give you superior sound quality. It uses the recently allocated 900 MHz band which means less interference, clearer sound, and greater range than 46/49 MHz cordless telephones. Its cordless operation and dual keypads let you make or answer calls just about anywhere in your home or office. Its features include:
900 MHz Operation — provides better sound and less interference than many other cordless phones.
Digitally Encoded Signal — prevents other people from picking up your phone’s signal and listening to your conversations.
Dual Keypads — a full set of keys on both the ET-910’s handset and base let you use either keypad to make and answer calls or program its features.
Speakerphone — lets you make or answer calls without using the handset.
10-Number Memory Dialing — lets you store up to 10 phone numbers in memory for easy dialing.
Security Access Protection Code
— changes each time you place the handset on the base, to minimize the chances of other cordless phones using your phone line.
10 Channels — scans 10 channels (frequency pairs used between the base and the handset) and automatically selects the one with the least interference each time you make or receive a call, and lets you change the channel during a call.
Out of Range Signal — the handset beeps to let you know when you move out of the base’s operating range.
Two-Way Intercom/Paging System
— lets you send a signal from the base to the handset, or from the handset to the base, so you can page someone or easily locate the handset when it is away from the base. If someone answers, you can use the ET-910 like a two-way intercom.
Any-Key Answer — lets you press any key on the handset (except OFF) to answer an incoming call.
let you adjust the volume of the sound you hear through the handset and the speakerphone.

Programmable Ringers — let you select from four ringer types and turn the ringer on or off from both the handset and the speakerphone.
Handset/Base Disable — lets you disable the ET-910’s handset or base during a call to prevent anyone from interrupting your call at the other keypad.
Privacy — prevents the person on the other end of the phone line from hearing your conversation with someone in the room.
Flash — sends an electronic switchhook signal for use with special phone services such as call waiting.
Redial — lets you quickly dial the last number dialed.
Touch Tone (DTMF) or Pulse Dialing — lets you use your phone with either type of dialing.
Hearing Aid Compatible — lets you use this telephone with hearing aids that have a T (telephone) switch.
This phone has been tested and found to comply with all applicable UL and FCC standards.
For your records, we recommend you record the phone’s serial number in the space below. The number is located on the bottom of the base.
Serial Number:
Important: Cordless phones such as this one require AC power to operate. When AC power is off, you cannot dial out or receive incoming calls using your ET-910. For this reason, the ET-910 should not be your only telephone. To be safe, you should also have a phone that does not require AC power to operate (not a cordless phone) so you can still make and receive calls if there is an AC power failure.
Warning: To prevent fire or shock hazard, do not expose this product to rain or moisture.

READ THIS BEFORE INSTALLATION
Your telephone conforms to federal regulations, and you can connect it to most telephone lines. However, each device 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 label on the base’s back.
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 phone might not ring. In rural areas, a total REN of three might impair ringer operation. If ringer operation is impaired, remove 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 label on the base’s back.
You must not connect your phone to any of the following:
•Coin-operated systems
•Party-line systems
•Most electronic key phone systems
Note: 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.

INSTALLATION
SELECTING A
LOCATION
You can set the ET-910’s base on a flat surface (such as a desktop or counter-top), mount it on a modular jack wall plate, or mount it directly on the wall. The base’s location affects the phone’s range. If you have a choice of several locations, try each to see which one provides the best performance.
Select a location that is:
•Near an AC outlet
•Near a telephone line jack
•Away from electrical machinery, electrical appliances, and metal walls or filing cabinets
•Away from wireless intercoms, alarms, and room monitors
If the phone line jack is not a modular jack, you must update the wiring. You can convert the wiring yourself, using jacks and adapters available at your local Radio Shack store. Or, you can let the phone company update the wiring for you.
Notes:
•The phone company charges for the installation of the necessary jacks.
•The USOC number of the baseboard jack to be installed is RJ11C.
•After you mount the phone, you must install the battery pack and charge it for 24 hours before you use it the first time. See “Preparation” on Page 12.
