Power Sources Operating time of the battery pack A fully-charged battery pack provides approximately 2 hours of continuous use. We recommend that you should prepare more than two battery packs when using DT-120 or recording in the long-recording mode. If you use the battery pack in a cold place, its operating time is shortened. When the battery becomes weak The .r3 indication blinks in the display window. Replace the battery pack with a fully charged one after turning off the power. If you leave the unit with the cs\-] indication blinking, the unit will be turned off automatically in 5 minutes. The battery pack heats up During charging or recording, the battery pack or the AC power adaptor heats up. This is not dangerous. Life of the battery pack When the operating time of the fully-charged battery pack becomes short, purchase a new one and use it. If you plug in the AC power adaptor to the unit while operating the unit with the battery pack The unit stops operating automatically. Note On treatment • Keep the metal terminals on the battery pack away from metal objects, otherwise it may short circuit. On charging • Charge the battery pack directly before using it. • Recharge the battery pack only when it is exhausted. (When the c_sc3 indication begins to blink in the display window, it indicates that the battery pack is exhausted.) • If you do not use the battery pack for a long time, it becomes fully discharged. A discharged battery cannot be charged to its fully capacity in 1 charge and its operating time becomes short. In this case, recharge 2 or 3 times. (Do not repeat charging except in this case since the battery pack may become damaged.) How to care for the battery pack Remove the battery pack from the unit after using it, and keep it in a cool and dry place. When the battery pack is attached to the unit, a small amount of current flows to the unit even if the power is turned off. This may overdischarging and shorten battery life. 16
