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 yourET-543.For this reason, the ET543 cordless phone 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 youcan still make andreceive calls if there is an AC power failure.

This telephone has been tested and found to comply with all applicable UL and FCC standards.

Your ET-543operates on standard radio frequencies, as allocated by the FCC. Therefore, it is possible for other radio units operating on similar frequencies, within a certain area, to inadvertently intercept your conversations and/or cause interference on your cordless telephone. This lack of privacy can occur with any cordless telephone.

For your records, we urge you to record the serial number of your phone in the space below. The serial number is located on the bottom panel of the base.

READ THIS BEFORE INSTALLATION

We have designed your telephone to conform to federal regulations, and you can connect it to most telephone lines. However, 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 your phone’s 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 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.

4

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 located on the bottom of your phone’s base.

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

Coin-operatedsystems

Party-linesystems

Most electronic key phone systems

INSTALLATION

SELECTING A LOCATION

Select a location for the telephone that meets these requirements:

Near an AC outlet

Near a telephone line jack

Out of the way of normal activities

Away from electrical machinery, electrical appliances, and metal walls or filing cabinets

Away from wireless intercoms, alarms, and room monitors

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

If the phone line jack is not a modular jack, you must 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.

Notes:

The phone company will charge you for the installation of the necessary jacks.

The USOC number of the jack to be installed is RJ11C.

INSTALLING THE PHONE

Follow these steps to install the base on a desk, shelf, or table.

1.Plug one end of the supplied modular cord into the phone jack on the back of the base.

2.Plug the modular cord’s other end into a modular phone line jack.

3.Insert the supplied AC adapter’s barrel plug into the DC 12V jack on the back of the base.

4.Plug the adapter into a standard AC outlet.

For the best reception, fully extend the base’s antenna and place it in a vertical position.

Caution: You must use a 120V AC/ 12V DC adapter that delivers at least 200 milliamps. Its center tip must be positive, and its plug must correctly fit the phone’sDC 12V jack. The supplied adapter meets these requirements. Using an adapter that does not meet these requirements could damage the phone or the adapter.

PREPARATION

CONNECTING THE

BATTERY

Before you use your phone for the first time, you must connect and charge the battery.

Slide off the battery compartment cover on the back of the handset. Connect the battery’s plug to the pins inside the compartment.

Replace the cover, then follow the instructions under “Charging the Battery.”

CHARGING THE

BATTERY

Before you charge the battery, set POWER toOFF. Then place the handset on the cradle so the CHARGE/ TALK indicator lights and let the battery charge for about 15 hours.

When on the handset lights, recharge the battery. To avoid damage to the battery, always recharge the handset before battery power grows too weak to light .

Notes:

You can set POWER toON while the battery charges.

If the CHARGE/TALK indicator does not light when you place the handset on the cradle, be sure the battery is connected to the pins inside the battery compartment and the AC adapter is securely connected to the base. Also, check the charging contacts on

7

43-1043.fmPage 8 Tuesday, August 17, 1999 10:36 AM

the handset and base. If the contacts are dirty or tarnished, gently clean them with a pencil eraser.

About once a month, fully discharge the battery by keeping the handset off the cradle until flashes, then return the handset to the cradle and fully recharge the battery. If you do not fully discharge and recharge the battery periodically, it loses its

ability to fully recharge.

The first time you use your phone after charging a new battery, the handset might not work and might sound an error tone when you press TALK. This might also occur when you recharge a battery that has been completely discharged. If this happens, be sure the handset is turned on, then return the handset to the cradle for 5 seconds. This resets the security access code.

SETTING THE DIALING MODE

Set 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.

1.Set TONE/PULSEto TONE.

2.Lift the handset and listen for a dial tone.

3.Press any number other than 0.

If the dial tone stops, you have touch-tone service. Leave TONE/ PULSEset to TONE.

If the dial tone continues, you have pulse service. Set TONE/ PULSEto PULSE.

OPERATION

Your ET-543’sLCD display shows telephone numbers as you dial them or when you recall them from memory. It shows the current channel number and lets you know when battery power is growing weak or the phone is out of range of the base. The display also shows indicators when you press

FLASH/DEL or PAUSE.

To make a call, lift the handset from the base and press TALK so the keypad and the CHARGE/TALK indicator on the base light.

MAKING/ANSWERING A CALL

You can use your cordless telephone in two ways: at the base or away from the base.

Note: CH and the currently used channel number appear on the display. This number might change when you return the handset to the base.

To disconnect a call, replace the handset on the base.

Using the Handset

at the Base

You can use the handset at the base like a regular corded telephone. Just set POWER toON and place the handset in the cradle.

To answer a call, just lift the handset from the base.

43-1043.fmPage 10 Tuesday, August 17, 1999 10:36 AM

You can make or answer a call on a phone on the same line as the cordless phone, even if the handset is away from the base.

RANGE appears when the distance from the handset to the base is out of the phone’s range.

The keypad lights on the handset turn off if no button is pressed for more than 13 seconds.

REDUCING

INTERFERENCE

To reduce interference, press CH to switch to the next channel (25 channels in all) until you receive the best reception.CH and the channel number appear on the display.

To quickly redial the last number you dialed, simply lift the handset from the base and press TALK again so the CHARGE/TALK indicator lights, and then pressREDIAL. The redialed number appears on the display.

10

The redial memory holds up to 80 digits in the tone or pulse mode. The redial memory also holds pause entries (see “Entering a Pause” under “Memory Dialing”).

Note: We recommend you not useREDIAL to dial numbers that include a tone (*) entry (see “Using Tone Services on a Pulse Line”).

USING FLASH/DEL

Use FLASH/DEL on the handset to perform the switchhook operation for special services, such as call waiting.

For example, if you have call waiting, press FLASH/DEL to take an incoming call without disconnecting the current call.FLASH appears. PressFLASH/ DEL again to return to the first call.
