PREPARATION

INSTALLING THE BATTERY

To install the battery, place

 

it flat against the back of

Tab

the phone with the tab fac-

 

ing up and toward the top

 

of the phone. Then slide

 

the battery toward the top

 

of the phone until it snaps

 

into place.

 

To remove the battery, be sure the phone is turned off, then hold down the tab and slide the battery down and lift it off the phone.

IMPORTANT BATTERY TIPS

You must fully charge a new battery at least 24 hours before you first use it. See “Charging the Battery” on Page 10.

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

A new battery’s full performance is achieved only after two or three complete charge and discharge cycles.

When you are not using the charger, disconnect it from power. Do not leave the battery connected to the charger for more than a week, since overcharging could shorten the battery’s life. If left unused, a fully charged battery discharges itself in about a week.

8

17-1165.fmPage 9 Wednesday, July 21, 1999 2:46 PM

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.

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

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, it is time to get a new battery.

Leaving the battery in a hot or cold place, such as in a closed car in the summer or winter, reduces the battery’s capacity and life. Always try to keep the battery between 59° and 77°F (15° and 25°C). A phone with a too hot or too cold battery might not work, even when the battery is fully charged, until the battery returns to a normal temperature. Nickel metal hydride (NiMH) batteries are particularly limited in temperatures below 14°F (–10°C).

Use the battery only for its intended purpose.

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

9

17-1165.fmPage 10 Wednesday, July 21, 1999 2:46 PM

Do not short circuit the battery. Accidental short circuiting can occur when a metal object (coin, paper clip, pen, or similar) directly connects the battery’s + and – terminals (the metal strips on the back of the battery), such as when you carry a spare battery in your pocket or purse. Short circuiting the terminals might damage the battery or the object connected to it.

Do not dispose of batteries in a fire!

Nickel Cadmium and Nickel Metal Hydride batteries must be recycled

or disposed of properly. They must

NiCd not be disposed of in municipalNiMh waste.

CHARGING THE BATTERY

Once you install the battery on the phone, follow these steps to charge the battery using the supplied charger.

1. Insert the charger’s barrel plug into the jack on the bottom of the phone.

2.Connect the charger’s AC plug to a standard AC outlet. The phone’s battery charge bar appears and begins to scroll.

10

17-1165.fmPage 11 Wednesday, July 21, 1999 2:46 PM

Notes:

You can use your phone during charging. For faster charging, however, do not use the phone and turn it off.

If the battery is too hot or cold, charging stops until the battery temperature returns to normal.

3.The battery charge bar stops scrolling when the battery is fully charged. Disconnect the charger from the AC outlet first, then disconnect it from the phone.

Using the supplied battery (fully charged), you have about 2 hours of talk time or 26 hours of standby time.

When to Recharge the Battery

Your phone displays the battery charge bar whenever the phone is on to keep you informed about the battery’s power level. The higher the bar, the more power there is left in the battery.

You can recharge the battery (as described in “Charging the Battery” on Page 10) at any time. However, when your phone gives you these lowbattery indications, recharge the battery as soon as possible:

When only a few minutes of talk time remain, the phone sounds a warning tone and displays BATTERY LOW at regular intervals.

11

17-1165.fmPage 12 Wednesday, July 21, 1999 2:46 PM

When the battery charge level is too low for the phone to operate, the phone displays RECHARGE BATTERY and sounds a warning tone. The phone automatically turns off about 10 seconds later.

Note: The phone doesnot sound low battery warning tones if silent service is set to on (see “Ring Type” on Page 40).

DISCHARGING BATTERIES

Rechargeable batteries last longer and perform better if allowed to fully discharge occasionally. You can do this by leaving the phone on until the phone 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.

3.To end the call, press .

Signal Strength

The vertical bar on the left of the display shows the strength of the cellular signal your phone is receiving. The higher the bar, the stronger the signal.

If the signal strength is low, try moving to a different location. If you are using the phone in a building, try moving closer to a window.

If NO SVC appears, the phone is outside the cellular service area. This means you cannot make or receive calls until you move the phone back inside the cellular service area.

14

17-1165.fmPage 15 Wednesday, July 21, 1999 2:46 PM

RECEIVING A CALL

The phone displays VOLUME and a horizontal bar indicating the volume level. The more filled bar segments, the higher the volume.

15

17-1165.fmPage 16 Wednesday, July 21, 1999 2:46 PM

MAKING EMERGENCY CALLS

We program your primary local emergency number (such as 911) into your phone at the time of activation. To prevent unwanted emergency calls, however, your phone’s one-touchemergency dialing feature is preset to off. To set it to on, see “TurningOne-TouchEmergency Dialing On/Off” on Page 28.

To quickly dial the emergency number (if one-touch emergency dialing is set to on), hold down until the phone displays EMERG. CALL TRY.

Notes:

The emergency number programmed into your phone might not be valid in all areas. (For example, not all areas have 911 service.) If you use the phone outside its primary service area, you might have to manually dial an emergency number that is different from the one programmed into your phone.

One-touchemergency dialing does not operate if keyguard is turned on (see “Turning Keyguard On/Off” on Page 29) or ifone-touchemergency dialing is turned off.

Important: When you make an emergency call, give your name and cellular phone number, as well as the location of the incident. Remember that your phone might be the only means of communication at the accident scene. Do not end the call until you are advised you may do so.

17-1165.fmPage 20 Wednesday, July 21, 1999 2:46 PM

Hints:

Using Memory Location 1 — If one-touch dialing is set to on (see “One-Touch Dialing” on Page 40), you can hold down for about 1 second to quickly dial the number stored in memory location 1. For convenience, store a frequently called telephone number (such as your home or office number) in this location.

Using Memory Location 20 — Setting the phone to use the call restriction level INCOMING ONLY (see “Selecting a Call Restriction Level” on Page 26) does not prevent you from speed-dialing the number stored in memory location 20. If you plan to use this call restriction level, store a frequently called telephone number (such as your home number or some other “priority” number) in memory location 20.

Using Quick Store

To quickly store a phone number in the first unused speed-dialmemory, enter the phone number, then hold downfor about 1 second. The phone briefly displaysSTORED and thespeed-dialmemory number it selected.
