Vibration and Silent Alert Modes — let you set the phone to vibrate gently (instead of ring) when it receives a call, or make no sound or movement at all, to avoid disturbing others.

Nine Different Ringer Styles — let you set the phone’s ringer to help you distinguish your phone’s ring from that of another phone.

Easy-to-ReadSeven-CharacterDisplay— bright red LED characters let you see essential call information in almost any lighting condition.

Call Timers — let you keep track of the individual and cumulative call time(air-time),and includes a timer that you can reset as you wish (so you can track monthly airtime, for example).

17-1111.fmPage 8 Wednesday, July 21, 1999 2:23 PM

NoSvc (No Service) Indicator

Flashes or lights steadily if the phone is beyond the range of the cellular service area, meaning calls cannot be made or received. See “Signal Strength/Service Area” on Page 14.

Roam Indicator

Flashes or lights steadily if the phone is accessing a service area outside of your home system (roaming). See “Roaming” on Page 59.

READING THE DISPLAY

Your phone’s display provides a full range of messages and indicators to assist you with the phone’s operation. Since many of these messages contain more characters than your phone can display at one time, the phone displays most messages across more than one display. For example, the phone displays Signal then (within about 1 second)Mtr On to indicate that the signal meter display feature is turned on.

Note: When referring to a displayed message, this manual includes the entire message (such asSignal Mtr On).

For a complete listing of display messages and indicators, see “Display Message Glossary” on Page 73.

USING THE BATTERY

Warning: A detached battery could cause property damage, injury, or burns if a metal object (such as a pen spring, beaded chain, or piece of jewelry) contacts the battery’s terminals and causes a short circuit. Be careful when placing a charged battery inside a coat pocket, purse, or other container that might contain metal objects.

Caution: Nickelmetal-hydride(NiMH) batteries must be recycled or disposed of properly. They must not be disposed of in municipal waste.

INSTALLING THE BATTERY

Latch

Align Here

1.Place the battery flat against the back of the phone and align the top of the battery below the raised arrows.

2.Slide the battery toward the top of the phone until it snaps into place.

9

17-1111.fmPage 10 Wednesday, July 21, 1999 2:23 PM

To remove the battery, be sure the phone is turned off, then press the latch at the top of the battery and slide the battery toward the bottom of the phone until it stops. Then lift the battery off the phone.

Note: If you have an extra charged battery and the currently installed battery becomes low during a call, you can change the battery without ending the call or losing the connection. See “Replacing a Battery During a Call” on Page 12.

CHARGING THE BATTERY

The nickel metal-hydride(NiMH) battery supplied with your telephone is shipped in a discharged state to extend the battery’s life. It must be fully charged before you can use your phone.

We recommend that you charge a new battery overnight, but no longer than 24 hours, using the AC charger supplied with your phone. Recharging time for the supplied battery is about 3 hours, although the time varies based on the amount of charge left in the battery. For the recharging time of any other battery type, see the instructions provided with that battery.

Follow these steps to charge the supplied (or any approved) battery using the charger supplied with your phone.

1.Install the battery on the phone.

2.Insert the charger’s flat plug into the charging jack on the bottom of the phone.

Note: The plug fits into the jack only one way. If you have difficulty inserting the plug, turn it over and try again. Do not force it!

3.Plug the charger’s power cord into a standard AC outlet.

10

17-1111.fmPage 11 Wednesday, July 21, 1999 2:23 PM

Notes:

You can use the phone while it is charging, but charging takes longer.

For the fastest charging, be sure the phone is turned off during charging, if you are not expecting a call.

If the phone is on when you connect the charger, the phone beeps once and the keypad backlight remains on until you disconnect the charger.

4.When the battery is fully charged, disconnect the charger from the AC outlet. Then press in the clips on the sides of the plug and pull it away from the phone to disconnect the charger.

CHECKING BATTERY POWER

When battery power becomes low, the phone displays Low Bat and sounds a warning tone every few seconds. When power becomes too low for the phone to operate, it automatically turns off. Recharge the battery as soon as possible.

To check the battery’s charge level at any time, press FCN GHI 4 . The battery strength meter appears on the display for about 5 seconds. The more bars that appear on the meter, the higher the battery’s current charge level. If few or no bars appear, the battery’s power is low.

Notes:

If you press FCN GHI 4 while the phone is charging, the phone flashesChrging Battery for about 5 seconds instead of the battery strength meter.

11

17-1111.fmPage 12 Wednesday, July 21, 1999 2:23 PM

Note: Rechargeable batteries last longer and perform better if occasionally allowed to fully discharge. You can do this by leaving the phone on until it automatically turns off or you can use the battery discharge feature of any approved accessory available for your phone. Do not try to discharge the battery by any other means.

REPLACING A BATTERY

DURING A CALL

If you have an extra charged battery and the currently installed battery becomes low during a call, follow these steps to change the battery without ending the call or losing the connection.

1.Tell the other party on the line what you plan to do (tell them, for example, that they will hear some noise as you remove the battery and you will call back if for any reason you lose the connection).

2.Remove the battery, and within 3 seconds, install the fresh battery. Your call is still on the line.

Note: If you do not complete Step 2 within 3 seconds, the call disconnects.

12

17-1111.fmPage 13 Wednesday, July 21, 1999 2:23 PM

IMPORTANT BATTERY TIPS

Use only the supplied charger and use only batteries designed for this phone.

You can purchase additional standard or extended capacity batteries through your local RadioShack store.

When you are not using the charger, disconnect it from power. Do not leave the battery connected to the charger for more than 24 hours, since overcharging could shorten the battery’s life.

When the battery is not in use, store it uncharged in a cool and dark place.

The battery is a sealed unit with no serviceable parts. Do not try to open the case.

For the best results, be sure the battery is at or near room temperature when you charge it.

A battery can be charged and discharged hundreds of times, but it eventually wears out. When the operating time (talk time and standby time) is noticeably shorter than normal, get a new battery and recycle or properly dispose of the old one.

Do not dispose of batteries in a fire.

Never use any charger or battery that is damaged or worn out.

BASIC OPERATION

TURNING THE PHONE ON/OFF

To turn on the phone, flip down the cover then pressPWR . The phone performs a short self test and sounds a tone or vibrates (see “Changing the Alert Type” on Page 29), then the signal strength meter appears (see “Signal Strength/Service Area”) and the keypad backlight turns on for about 16 seconds. The phone is ready to use when the green power/lock indicator begins to flash.

Notes: The keypad backlight turns on for about 16 seconds every time you press a key, then it turns off and the display goes blank to conserve battery power.

To turn off the phone, pressPWR again. The display goes blank and the green on/lock indicator turns off.

SIGNAL STRENGTH/SERVICE AREA

Each time you turn on the phone, clear the display, or make a call, the signal strength meter appears on the display to indicate the strength of the cellular signal currently being received. The more bars that appear on the meter, the stronger the signal.

Notes:

If few or no bars appear (meaning the signal strength is weak) and you want to make or receive a call, move the phone to a different location so the signal strength increases.

14

17-1111.fmPage 15 Wednesday, July 21, 1999 2:23 PM

You can disable the signal strength meter so it does not appear. See “Turning the Signal Strength Meter Off/On” on Page 26.

If the NoSvc indicator (above the display) turns on, the phone is outside the cellular service area and you cannot make or receive calls until you reach an area with service your phone can use.

MAKING A CALL

1.Extend the antenna, flip open the cover, and be sure the phone is on (the green power/lock indicator is flashing).

2.Press the number keys to enter the phone number you want to dial (including the area code, if necessary). The numbers appear on the display as you press them.

Notes:

If you make a mistake, repeatedly press CLR to delete one digit at a time, or hold downCLR to delete all digits.

The phone can display up to 7 characters at once. If you enter (or display a message containing) more than 7 characters, the characters automatically scroll off the left side of the display. Press RCL at any time to recall the overflow characters. See “A Number Longer than Seven Digits” on Page 21.

3.Press SND to dial the phone number. The InUse indicator flashes and the phone briefly displaysDialing then the number called, then the signal strength meter.

4.To end the call, press END.

Note: Closing the cover doesnot end or disconnect a call.
