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 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 an 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

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.
