Security Features — to prevent unauthorized phone use, you can set up to three different levels of call restrictions (to allow only incoming calls, for example) while still allowing calls to the preprogrammed emergency number.

One-TouchEmergency Dialing— lets you dial the emergency number preprogrammed into your phone, by briefly holding down the 9WXYZ key.

Scratchpad Memory — lets you temporarily store a number (during a call, for example), then easily dial it or store it in memory.

Ample Talk and Standby Time — the supplied battery (fully charged) provides about 1 hour, 40 minutes of talk time or 21 hours of standby time.

Silent Service — lets you set the phone to quietly beep instead of ring when it receives a call, to avoid disturbing others.

Call Timers — let you keep track of the individual and cumulative call times(air-time),and includes a timer that you can reset at any time.

Two Phone Number Capability — lets you use this one phone with two different cellular services, with a different phone number from each.

PREPARATION

INSTALLING THE BATTERY

To install the battery, place

Tab

it flat against the back of

 

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, 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 charger connected 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

17-1101.fmPage 9 Wednesday, July 21, 1999 9:57 AM

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 battery that is too hot or too cold 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

17-1101.fmPage 10 Wednesday, July 21, 1999 9:57 AM

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 beeps and its battery charge bar appears and begins to scroll.
