Cautions concerning the rechargeable

battery

Read the following descriptions carefully before using the Ni-MH rechargeable battery.

Discharging:

The rechargeable battery self-discharges while not in use. Be sure to charge it fully before use.

Operating temperature:

The rechargeable battery is a chemical product. The efficiency of the rechargeable battery may fluctuate even when

the battery is operating within the recommended temperature range. This is an inherent nature of such products.

Recommended temperature range:

When operating the recorder: 0°C - 42°C/ 32°F - 107.6°F

Charging:

5°C - 35°C/ 41°F - 95°F

Storage for a long period: –20°C - 30°C/ –4°F - 86°F

Using the rechargeable battery outside the above temperature range may result in declining efficiency and a shorter battery life. In order to prevent battery leakage or rust, remove the rechargeable battery from the recorder when you will not be using it for a long time, and store it separately.

Notes

•This recorder is designed to fully charge the battery regardless of its energy level. However, for best results when charging a newly purchased rechargeable battery or a battery that has not been used for a long time (more than one month), it is recommended to repeat the process of fully charging the battery and then letting it discharge 2 to 3 times.
