FEATURES

Your RadioShack CT-502Flip-StyleHandheld Cellular Telephone with Silent Vibrating Alert is astate-of-the-artpersonal cellular telephone. It has all of these features:

Special Messaging Service Features — the phone is preprogrammed to work with special (subscription-only) messaging services offered by many cellular carriers, including calling line ID, voice mail notification, and short (alphanumeric) messages.

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).

Speed/Memory Dialing — lets you store up to 50 phone numbers (of up to 32 digits each) and names (of up to 14 characters each) in memory and dial any of them by pressing one or two buttons.

Memory Scrolling — lets you rapidly search the memory locations for a number you stored.

Last Number Redial — lets you quickly review and redial any of the last 10 numbers that you called.

Scratchpad Memory — lets you temporarily store a number (even during a call), then easily dial it.

Security Features — to prevent unauthorized phone use, you can lock the phone (so it cannot be used at all) or set up to five different levels of service restrictions (so only local calls can be made, for example).

Multiple Key Answer — lets you set the phone so pressing one of several keys answers a call.

Ample Talk and Standby Time — the supplied battery provides about 85 minutes of talk time or 24 hours of standby time, when fully charged.

Battery and Cellular Signal Strength Meters easy-to- read graduated bar graphs let you quickly check the battery power remaining or the current cellular signal strength.

Automatic Answer — lets you set the phone to answer automatically after two rings (if you are using optional handsfree equipment, for example).

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

Handsfree Feature — the phone is preprogrammed to work with most optional handsfree equipment.

We recommend you record your phone’s Electronic Serial Number (ESN) here. The number is on the back of the handset under the battery.

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.
