Important Note: 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-551. 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.

WARNING: To reduce the risk of fire or shock hazard, do not expose this product to rain or moisture.

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER OR BACK. NOUSER-SERVICE-ABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.

This symbol is intended to alert you to the presence of uninsulated dangerous voltage within the product’s enclosure that might be of sufficient magnitude to constitute a risk of electric shock. Do not open the product’s case.

This symbol is intended to inform

!you that important operating and maintenance instructions are in-

cluded in the literature accompanying this product.

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 shown 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, your phones 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 shown on the bottom of the base.

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

Notes:

If the CHARGE indicator does not light when you place the handset on the base, be sure the battery pack and AC adapter are correctly and securely connected.

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.

10

If this happens, return the handset to the base for a few seconds.

If the LOW BATT indicator does not light, but the phone does not work, recharge the battery pack. The battery voltage might be too low to light the indicator.

If the battery pack gets weak during a call, the handset sounds three beeps every 30 seconds, and the LOW BATT indicator flashes for 2 minutes. After 2 minutes, the phone automatically disconnects. If this happens, you cannot make another call on the phone until you recharge the battery pack.

About every 30 days, fully discharge the battery pack by keeping the handset off the base until the LOW BATT indicator lights. Otherwise, the battery pack loses its ability to fully recharge.

Using a pencil eraser, clean the charging contacts on the handset and the base about once a month to make sure they are not dirty or tarnished.

43-1051.fmPage 11 Tuesday, August 17, 1999 1:08 PM

If the battery pack gets completely discharged, the ET-551loses the securityaccess-protectioncode. To reset the code, place the handset on the base and charge the battery pack.

The supplied battery pack should last 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 19).

SETTING THE DIALING MODE

Set T/P (Tone/Pulse) 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.

CARE AND MAINTENANCE

Your RadioShack ET-55125-ChannelCordless Phone with10-NumberMemory is an example of superior design and craftsmanship. The following suggestions will help you care for your cordless phone so you can enjoy it for years.

Keep the phone dry. If it gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits.

Handle the phone gently and carefully. Dropping it can damage circuit boards and cases and can cause the phone to work improperly.

Use and store the phone only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.

Keep the phone away from dust and dirt, which can cause premature wear of parts.

Wipe the phone with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone.

Modifying or tampering with the phone’s internal components can cause a malfunction and might invalidate your phone’s warranty and void your FCC authorization to operate it. If your phone is not performing as it should, take it to your local RadioShack store for assistance. If the trouble is affecting the phone lines, the phone company might ask you to disconnect your phone until you have resolved the problem.

18

43-1051.fmPage 19 Tuesday, August 17, 1999 1:08 PM

REPLACING THE

BATTERY PACK

If you follow the instructions in “Connecting and Charging the Battery Pack” on Page 9, the battery pack should last about one year. If the battery pack will not hold a charge for more than 2 hours after an overnight charge, replace it with a new 3.6 V, 300 mAh battery pack with a connector that fits the socket in the battery compartment. You can order a replacement battery pack through your local RadioShack store.

Install the new battery pack as described here, then charge the battery pack (see “Connecting and Charging the Battery Pack” on Page 9).

Note: To avoid losing phone numbers stored in memory, try to install and begin charging the new battery pack within about 2 minutes.

1.Press down and slide off the handset’s battery compartment cover as shown.

2.Gently pull out the battery connector to disconnect it, then remove the battery pack.

3.Insert a fresh battery pack and insert its connector into the socket inside the battery compartment.

4. Replace the cover.

Cautions:

You must use a replacement battery pack of the same size and type.

Do not dispose of the battery pack in a fire because it might explode.

Do not open or mutilate the battery pack.

Be careful not to short the battery pack by touching it with conducting materials, such as rings, bracelets, and keys. The battery pack or conductor might overheat and burn.

19

43-1051.fmPage 20 Tuesday, August 17, 1999 1:08 PM

Important: This phone contains a rechargeablenickel-cadmiumbattery pack. At the end of the battery pack’s useful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area. Some options that might be available are: municipalcurb-sidecollection,drop-offboxes at retailers such as your local RadioShack store, recycling collection centers, andmail-backprograms.

THE FCC WANTS YOU TO KNOW

In the unlikely event that your phone causes problems on the phone line, the phone company can temporarily discontinue your service. If this happens, the phone company attempts to notify you in advance. If advance notice is not practical, the phone company notifies you as soon as possible and advises you of your right to file a complaint with the FCC.

Also, the phone company can make changes to its lines, equipment, operations, or procedures that could affect the operation of this telephone. The telephone company notifies you of these changes in advance, so you can take the necessary steps to prevent interruption of your telephone service.

20

Your phone might cause TV or radio interference even when it is operating properly. To determine whether your phone is causing the interference, turn off your phone. If the interference goes away, your phone is causing the interference.

Try to eliminate the interference by:

Moving your phone away from the receiver

Connecting your phone to an AC outlet that is on a different electrical circuit from the receiver

Contacting your local RadioShack store for help

If you cannot eliminate the interference, the FCC requires that you stop using your phone.

Some cordless phones operate at frequencies that might cause interference to nearby TVs and VCRs. To minimize or prevent such interference, the base of the cordless phone should not be placed near or on top of a TV or VCR.
