Cautions concerning the rechargeable batteries

Read the following descriptions carefully when you use the Ni-MH rechargeable batteries.

Discharging:

The rechargeable batteries self-discharge while this is not in use. Be sure to charge them regularly before use.

Operating temperature:

The rechargeable batteries are chemical products. The rechargeable batteries efficiency may fluctuate even when operating within the recommended temperature range. This is an inherent nature of such products.

Recommended temperature range:

When operating appliance: 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

•When disposing rechargeable batteries, always observe the local laws and regulations. Contact you local recycling center for proper disposal methods.

•If Ni-MH rechargeable batteries are not fully discharged, protect against short- circuiting (e.g. by taping the contacts) before disposing.

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

Notes

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