CT-356 Cellular Phone w/40 Number Memory (170-1070) Batteries Faxback Doc. # 34404 INSTALLING THE BATTERY 1. Place the battery onto the back of the phone. 2. Push the battery toward the catch until the catch snaps into place. To remove the battery: 1. Turn off the power. 2. Press the locking catch at the top of the battery, then slide the battery down and off the phone. CHARGING A BATTERY Follow these steps to charge the battery. 1. Install the battery and connect the charger to the base of the phone. 2. Connect the charger to a standard AC outlet. The battery indicator bar starts scrolling. NOTES: You can use the phone while charging, but charging is reduced during the call. For the fastest charging, make sure the phone is off. If the battery is too hot or cold, charging stops until the battery temperature returns to normal. 3. When the battery is fully charged, the battery indicator bar stops scrolling. Disconnect the charger from the outlet and the phone. BATTERY CHARGE INDICATOR The battery charge indicator, ( \| B ), shows the battery charge level. The higher the bar, the more power is left in the battery. When the battery charge indicator has only one segment turned on, the battery is almost fully discharged. IMPORTANT BATTERY TIPS You must fully charge a new battery before you first use it. A new battery's full performance is achieved only after two or three complete charge and discharge cycles. Use only the supplied charger and use only batteries recommended for this phone. 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 its life. If left unused, a fully charged battery discharges itself in about a week. 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 Radio Shack store. BATTERIES The following battery option is available for your phone. Consult your local Radio Shack store for more information. Charging Time Example: Cat. No. 23-1013 Supplied Cat. No. Supplied Battery Charger 273-1216 950 mAh NiCd 4 hr 30 min. 1 h 30 min. NOTE: The above charging times are approximate. Talk and Standby Time Example: Cat. N0. 23-1013 TALK STANDBY Supplied Battery 950 mAh NiCd 2 h 26 h 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 buy a new battery. 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 option of any approved accessory available for your phone. Do not try to discharge the battery by any other means. Recharging Batteries When the battery power is low and only a few minutes of talk time remain, the phone sounds a warning tone and displays BATTERY LOW at regular intervals. 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: If silent service is on, the phone does not sound the warning tones. Recharge the battery as described in "Charging A Battery" on page 9. Battery Tips Leaving the battery in hot or cold places, 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 degrees F (15 and 25 degrees C). A phone with a too hot or too cold battery might not work, even when the battery is fully charged. The battery might need to return to a normal temperature. Nickel metal hydride (NiMH) batteries are particularly limited in temperatures below 14 degrees F (-10 degrees C). Use the battery only for its intended purpose. Never use any charger or battery that is damaged or worn out. 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), for example, when you carry a spare battery in your pocket or purse. Short circuiting the terminals might damage the battery or the connecting object. Dispose of used batteries in accordance with local regulations. Recycle! Do not dispose of batteries in a fire! Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries must be re- cycled or disposed of properly. Must not be disposed of in municipal waste. (LB/EB 08/15/96)
