When you are not going to use the unit for an extended time ≥ When storing the unit in a cupboard or cabinet, it is recommended that you place a desiccant (silica gel) in with it. About the battery If you drop the battery accidentally, check to see if the terminals are damaged. ≥ Inserting a battery with damaged terminals can damage the unit. Do not throw an old battery into fire. ≥ Heating a battery or throwing it into a fire may result in an explosion. 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 attached, a minute amount of current continues to flow even if the unit is off. Keeping the unit in this state may result in over discharge of the battery. This may result in you not being able to use the battery even 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%RH to 60%RH) ≥ 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. ≥ Prepare batteries enough to last for 3 to 4 times the period you are planning to record for. Cold places such as a ski resort can shorten recording time. 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 ≥ If the temperature of the battery is extremely high or extremely low, charging may take time or the battery may not be charged. ≥ 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, a minute amount of current is consumed.) ≥ Always keep the electrodes of the AC adaptor and battery clean. About status indicator during charging When the status indicator is flashing at a particularly fast or slow rate, the following should be considered. Flashing with approx. 4 second period (off for approx. 2 seconds, on for approx. 2 seconds): ≥ When the battery is over discharged or the temperature of the battery is too high or low. It can be charged, but it may take a few hours to complete the charging normally. ≥ It will flash in approx. 2 second intervals when normal charging resumes. Even in such cases, it may start flashing in approx. 4 second intervals until charging is completed depending on the conditions of use. - 247 -
