s Cautions for Use (continued) About the battery The battery used in this unit is a rechargeable lithium-ion battery. It is susceptible to humidity and temperature and the effect increases the more the temperature rises or falls. In cold areas, the full charge indication may not appear or the low battery indication may appear about 5 minutes after starting use. At high temperatures, the protection function may be triggered, making it impossible to use the unit. Be sure to detach the battery after use. ≥ If the battery is left inserted, a minute amount of current continues to flow even if the unit's power is off. Keeping the unit in this state may result in over discharge of the battery. The battery may become unusable after it is charged. ≥ The battery should be stored in the vinyl bag so metal does not come into contact with the terminals. ≥ The battery should be stored in a cool place free from humidity, with as constant temperature as possible. (Recommended temperature: 15 oC to 25 oC (59 oF to 77 oF), Recommended humidity: 40% to 60%) ≥ Extremely high temperatures or low temperatures will shorten the life of the battery. ≥ If the battery is kept in high-temperature, high-humidity, or oily-smoky places, the terminals may rust and cause malfunctions. ≥ To store the battery for a long period of time, we recommend you charge it once every year and store it again after you have completely used up the charged capacity. ≥ Dust and other matter attached to the battery terminals should be removed. Prepare spare batteries when going out for recording. ≥ In cold places such as a ski resort, the period during which you can record pictures is shortened. ≥ When you travel, do not forget to bring an AC adaptor (supplied) so that you can recharge the batteries at your destination. If you drop the battery accidentally, check to see if the terminals are damaged. ≥ Attaching a battery with damaged terminals can damage the unit. Do not throw old battery into fire. ≥ Heating a battery or throwing it into a fire may result in an explosion. ≥ If the operating time is very short even after the battery has been recharged, the battery has worn out. Please purchase a new battery. About the AC adaptor ≥ Be sure to use the supplied AC adaptor. ≥ If you use the AC adaptor near a radio, radio reception may be disturbed. Keep the AC adaptor 1 m (3.3 feet) or more away from the radio. ≥ When using the AC adaptor, it may generate whirring sounds. However, this is normal. ≥ After use, be sure to disconnect the AC adaptor. (If it is left connected, about 0.1 W of current is consumed at most.) ≥ Always keep the electrodes of the AC adaptor and battery clean. Put this unit near the outlet to make it easy for the interrupting device (plug) to reach it. About charging errors When the status indicator flashes rapidly or slowly, one of the following situations may be to blame. When the status indicator flashes at intervals of about 6 seconds (on for about 3 sec. and off for about 3 sec.): 110 VQT0X39
