FEATURES

Your RadioShack ET-6852-Line900MHz Spread Spectrum Cordless Speakerphone uses advanced cordless telephone technology to give you superior audio quality and extended range. TheET-685lets you make and receive calls on two separate telephone lines.

The ET-685’sCaller ID records each caller’s telephone number (and name, if available in your area) and the day and time of the call, as provided by your local phone company to Caller ID service subscribers. If you subscribe to Call Waiting with Caller ID, theET-685can even show you incoming caller information when you are already on the phone. Its other features include:

900 MHz Operation — provides longer range and less interference than many other cordless phones.

Two-LineTelephone System— lets you easily handle two telephone lines at the same time. You can use both lines to make 3- or 4-way conference calls, or one line for data communication while you are talking on the other.

Dual Keypads — a full set of keys on both theET-685’shandset and base lets you use either keypad to make and answer calls or use the phone’s features.

Speakerphone — lets you make or answer calls without using the handset.

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-685.To be safe, you should also have a phone that does not need AC power to operate (not a cordless phone) so you can still make and receive calls if there is an AC power failure.

When AC power is lost, the ET-685loses the securityaccess-protectioncode connection between the base and the handset. When power is restored, put the handset on the base briefly to restore this connection so you can use the handset.

READ THIS BEFORE INSTALLATION

We have designed your phone to conform to federal regulations and you can connect it to most phone lines. However, each device that you connect to the telephone line draws power from the line. We refer to this power draw as the phone's ringer equivalence number, or REN. The REN is on the bottom of your phone.

If you use 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 phones might not ring. If ringer operation is impaired, remove one of the devices from the line.

IMPORTANT CALLER ID INFORMATION

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

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

caller’s number only

caller’s name only

caller’s name and number

4

FCC STATEMENT

Your 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.

You must not connect your phone to any of the following:

coin-operatedsystems

party-linesystems

most electronic key phone systems

43-685.fmPage 5 Thursday, July 8, 1999 7:50 AM

This equipment complies with the limits for a Class B digital device as specified in Part 15 of FCC Rules. These limits provide reasonable protection against radio and TV interference in a residential area. However, your equipment might cause TV or radio interference even when it is operating properly. To eliminate interference, you can try one or more of the following corrective measures.

Reorient or relocate the receiving antenna.

Increase the distance between the equipment and the radio or TV.

INSTALLATION

MOUNTING THE PHONE

You can place the ET–685’sbase on a desk or table, or mount it on a standard wall plate or directly on a wall. Choose a location that is:

near an accessible AC outlet

near a modular telephone line jack

out of the way of normal activities

away from electrical machinery, electrical appliances, metal walls or filing cabinets, wireless intercoms, alarms, and room monitors

away from other cordless phones

The base’s location affects the handset’s range. If you have a choice of several locations, try each to see which provides the best performance.

Caution: The supplied AC adapter was designed specifically for yourET-685.Use only the supplied adapter.

connect one line through a one-linemodular phone jack

Notes:

Your phone connects directly to a modular phone line jack. If your phone wiring does not have a modular jack, you can update it using jacks and adapters available at your local RadioShack store. Or, you can have the phone company update it for you.

The line that connects a two-linephone jack to the phone company wiring must betwisted-paircable. Otherwise, you might hear interference (crosstalk) between the two lines.

The USOC number of the two-linejack to be installed is RJ14C (RJ14W for awall-plate).The USOC number of asingle-linejack is RJ11C.

Connecting to the Phone Lines

To take full advantage of the ET-685’scapabilities, you must have two phone lines with separate phone numbers. If you have only one line, you can order a second from your phone company.

You can connect the ET-685to the lines in one of the these ways:

CONNECTING AND CHARGING THE BATTERY PACK

The ET-685comes with a rechargeablenickel-cadmiumbattery pack in the handset but not connected. Before using your phone, you must connect the battery pack, then charge it for about 24 hours.

1.Slide open the battery compartment cover and lift the battery pack out of the compartment.

2.Plug the battery pack’s connector into the socket in the compartment. The connector fits only one way.

3.Replace the battery pack and the cover.

Recharge the battery pack when the handset beeps every 3 seconds or Low Battery flashes on the handset’s display.

12

To charge the battery pack, place the handset either faceup or facedown on the base. The CHARGE indicator on the base lights.

Important: Be sure the battery pack is properly connected before you try to charge it. The CHARGE indicator lights whenever the handset is on the base, even if the battery pack is not connected.

Notes:

When you first use the phone after charging or recharging the battery pack, the phone might not work and you might hear an error tone when you press LINE 1 orLINE 2. If this happens, return the handset to the base for about five seconds. This resets the securityaccess-protec-tion code.

If the battery pack gets weak during a call, the handset beeps every 3 seconds and Low Battery flashes on the handset’s display. When this happens, you cannot make another call on the phone until you recharge the battery pack.

43-685.fmPage 13 Thursday, July 8, 1999 7:50 AM

Use a pencil eraser to clean the charging contacts on the handset and the base about once a month.

If the battery pack becomes completely discharged or the base loses power while the handset is away from it, the security code might be lost. To reset the code, return the handset to the base. If it was the handset that lost power, leave the handset on the base to charge the battery pack.

About once a month, fully discharge the battery pack by keeping the handset off the base until the low battery indications (Low Battery flashing on the handset’s display and beeping) appear. Otherwise, the battery pack loses its ability to fully recharge.

The supplied battery pack should last for about a year. When the battery pack loses its ability to fully recharge, order a replacement battery pack from your local RadioShack store (see “Replacing the Battery Pack” on Page 34).

SETTING THE DIALING MODE

Set PULSE-TONE on the back of the base for the type of service you have. If you are not sure which type you have, do this test.

1.Be sure PULSE-TONE is set toTONE

(tone).

If the dial tone stops, that line has tone service.

13

43-685.fmPage 14 Thursday, July 8, 1999 7:50 AM

If the dial tone continues, that line has pulse service.

4.Press LINE 2, listen for the dial tone, and repeat Step 3.

If you have tone service on both lines, leave PULSE-TONE set to

TONE.

If you have pulse service on either line, set PULSE-TONEto PULSE

(pulse). You can use tone services on the line which supports them by pressing TONE/ before any other keys.
