CAUTION: Be sure you install all optional devices before you turn on your computer. 1. Place the computer on a flat, level surface. 2. To open the battery compartment, lift the two OPEN tabs under the battery compartment's cover. Then, slide off the cover. 3. Place the battery in the compartment. Be sure to position the battery so that it does not pinch or crimp the wires. 4. Plug the battery cord's connector into the battery jack. 5. Replace the battery compartment cover. 6. Insert the AC adapter's connector into the DC IN 9.5V jack. Then, plug the other end into a standard AC outlet, and let the battery charge at least 10 hours. WARNING: Be sure to match the notch on the connector with the notch in the plug. Do not force the connector into the jack. Forcing the connector in backwards can damage the battery and your computer. NOTES: * You must connect the AC adapter to charge the battery. Charge it for about 10 hours before you use the computer with the battery only. * We recommend you use your computer with the AC adapter whenever possible. The AC adapter supplies power for the computer and charges the battery. * Never store the battery uncharged. If you store the battery uncharged for more than two weeks, the battery can be permanently damaged. * Do not store your battery in high temperature locations for extended periods. Using the AC Adapter: The supplied AC adapter powers your computer and charges the battery. We recommend you use the adapter whenever possible. The following procedure tells you how to install the AC adapter. CAUTION: * Using an AC adapter other than the one supplied might harm the battery or the computer. * Unplug the AC adapter before you disconnect the connector from the computer. To use the AC Adapter and Charge the Battery: 1. Slide the battery into the battery compartment and plug the battery connector into the battery jack. 2. Insert the AC adapter's barrel connector into the computer's DC IN 9.5V jack. 3. Plug the adapter into a standard AC outlet and let the battery fully charge before you use the computer on battery power. You can immediately begin using the computer on AC power. Charging the Battery: Your Tandy 1110 HD comes with a battery that lets you use your computer anywhere you go. Before operating the computer on battery power, you must charge the battery for about 10 hours. You can operate the computer for up to 3 1/2 hours from a fully-charged battery. Your computer uses a sealed lead-acid rechargeable battery similar to your car battery. The battery lasts longest if you: * Keep the battery fully charged as much as possible. * Avoid completely draining the battery. * Keep the computer connected to AC power whenever possible. * Never store the battery fully discharged. If you follow these guidelines, the battery can power your computer for hundreds of recharge cycles. Low-Battery Indications: The low-battery (CHARGE/LOW BATTERY) indicator above the keyboard and the computer's beeper tell you the condition of the battery in the following four ways: * Indicator lights yellow during charging. * Indicator blinks slowly and beeper sounds for 30 seconds when the battery drains below the power level needed for normal operation. When this happens, save all important information and turn off the computer or connect the AC adapter. NOTE: The indicator might blink during disk operations. If the indicator turns off after the disk drive turns off, the battery still has plenty of power. * Indicator blinks rapidly about 20 minutes after it first starts blinking. You now MUST use the AC adapter, because the computer does not have enough power to save your information on the hard drive or a diskette. * About 5 minutes after the indicator starts blinking rapidly, the battery will not have enough power to operate the computer. WARNING: Your computer loses all information not saved onto the hard drive or a diskette when the power turns off.
