Handheld Cellular Phone
FEATURES
Your RadioShack CT-400 Handheld Cellular Phone combines advanced technology and design simplicity. To complement its small size and easy­to-use design, the CT-400 provides a full range of features.
Easy-to-Read Digital Display
— the supertwist liquid-crystal display provides essential call infor­mation and can be easily read from almost any an­gle.
Specia l Ce llu lar Ser vic e Fe atur es
— the phone is preprogrammed to work with special (subscription­only) messaging services offered by many cellular carriers, incl uding calling line ID and voice mail no­tification.
One-Touch Dialing Memory
— lets you dial an
important number at the touch of a single button.
Memory Dialing
— lets you store up to 40 phone numbers and names in memory, and dial any stored number by simply entering its one- or two­digit memory number (1–40).
Call Register Lists
— let you quickly review and redial any of the last 10 numbers that you called, and (if you subscribe to the appropriate cellular services) the numbers for any of the last 10 calls you missed or received.
Keyguard
— helps prevent accidental key presses
when the phone is in a pocket or bag, for example.

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-Touch Emergency Dialing — lets you dial the emergency number preprogrammed into your
WXYZ
phone, by briefly holding down the key.
9
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 phon e num ber from each.
We recomme nd yo u recor d your phon e’s Ele ctron ic Se ­rial Number (ESN) here. The number is on the handset under the battery.

PREPARATION
INSTALLING THE BATTERY
To install the battery, place it flat against the back of the phone with the tab fac­ing up and toward the top of the phone. Then slide the battery toward the top of the phone until it snaps into place .

IMPORTANT BATTERY TIPS
• You must fully charge a new battery at least 24 hours before you firs t 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 coul d shorten the battery’s life.
• If left unused, a fully charged battery discharg­es itself in about a week.
8
• 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 batt ery 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 ful ly 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.

17-110 1.fm Page 10 Wednesday, J uly 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
NiCd NiMH
or disposed of properly. They must not be disposed of in municipal 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.
10
17-110 1.fm Page 11 Wednesday, J uly 21, 1999 9: 57 AM
Notes:
• You can use your phone during charging, but charging takes longer.
• For the fastest charging, be sure the phone is turned off, if you are not expecting a call.
• 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 1 hour, 40 minutes of talk time or 21 hours of standby ti m e.
When to Re ch arge 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 left in the battery.
11
17-110 1.fm Page 12 Wednesday, J uly 21, 1999 9: 57 AM
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 i ndications, r echarge 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
• When the battery charge level is too low for the phone to operate, the phone displays

DISCHARGING BATTERIES
Rechargeable batteries last longer and perform better if occasionally allowed to fully discharge. 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.
