ET-475 (430-0527B) Preparation Faxback Doc. # 7327 CHARGING THE BATTERY Recharge the battery when the BATT LOW indicator lights. Note: If battery power is low, POWER is ON, and the handset is not in use, BATT LOW slowly flashes. If battery power is too low, the BATT LOW indicator does not light. When you recharge the battery, you can set POWER to ON, but the battery recharges more quickly if you set POWER to OFF. When you install a new battery, set POWER to OFF. Then, charge the battery for at least 24 hours before you use the phone. To charge or recharge the battery, place the handset on the cradle. The CHARGE indicator lights. Notes: The first time you use the phone after you install a new battery, it might not work and you might hear an error tone. This also might happen after you recharge the battery when it has completely discharged. If this happens, be sure the handset is turned on. Then, return the handset to the cradle for 5 seconds. This resets the security access code. If the CHARGE indicator does not light when you place the handset on the cradle, be sure the battery and AC adapter are correctly and securely connected. Also, check the charging contacts on the handset and base. If the contacts are dirty or tarnished, clean them with a pencil eraser. About once a month, fully discharge the battery. Otherwise, the battery loses its ability to fully recharge. To fully discharge the battery, keep the handset off the cradle until the BATT LOW indicator comes on. Then, set POWER to OFF, return the handset to the cradle, and fully recharge the battery. REPLACING THE BATTERY If you follow the instructions in "Charging the Battery", the supplied battery should last for several years. When the battery loses its ability to fully charge, order a replacement battery through your local Radio Shack store. Install the battery as described here. Then, charge the battery as described under "Charging the Battery." 1. Remove the MEMORY directory and its plastic cover from the handset. 2. Use a small Phillips screwdriver to remove the screw that secures the battery compartment cover. Then, remove the cover by sliding it in the direction of the arrow. 3. Attach the battery's connector to the connector inside the battery compartment. Then, place the battery inside the compartment. 4. Replace the battery compartment cover and secure it with the screw. 5. Replace the MEMORY directory and its plastic cover. Please note the following when replacing the battery in the telephone: Use only a direct replacement battery (CTB-1T1350, available from Consumer Mail Center, through your local Radio Shack store). Do not dispose of the battery in a fire. The cell might explode. Check with local codes for possible special disposal instructions. Do not open or mutilate the battery. Released electrolyte is corrosive and might damage eyes or skin. It can be fatal if swallowed. Exercise care in handling the battery in order to not short it with conducting materials such as rings, bracelets, and keys. The battery or conductor might overheat and burn. SETTING THE DIALING MODE Set MODE for the type of service you have. If you are not sure which type of service you have, do this test. 1. Set MODE to TONE. 2. Lift the handset and listen for a dial tone. 3. Press any number other than 0. If the dial tone stops, you have touch-tone service. If the dial tone continues, you have pulse service. Set MODE to PULSE. (br/all-8/11/94)
