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

RISK OF ELECTRIC SHOCK.

 

 

 

DO NOT OPEN.

 

 

 

 

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:

coin-operatedsystems

party-linesystems

most electronic key phone systems

Near a 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 RadioShack adapter was designed specifically for yourET-551.Use only the supplied adapter.

Notes:

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

The USOC number of the jack to be installed is RJ11C (RJ11W if you want to mount it on a wall plate).

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.
