Charging the battery
Notes
• Charge the battery frequently during the first
period of use. The battery will perform better
after several charge/discharge cycles.
• Models of batteries which are different from the
included one may not be charged.
• Charging the battery via the USB cable connection
may not be successful depending on the power
capacity of the USB port in your PC. Use the AC
adapter (optional) instead.

Cautions concerning the battery
Read the following instructions carefully when you
use the battery.
Discharging:
Rechargeable batteries self-discharge while not in
use. Charge it regularly before use.
Battery life:
Over time, the rechargeable battery may gradually
wear down. When the operating time becomes
shorter even if the rechargeable battery is fully
charged under the specified condition, replace it
with a new one.
Operating temperature:
Rechargeable batteries are chemical products.
Battery efficiency may vary even when operating
within the recommended temperature range.
This is an inherent nature of these products.
Recommended temperature range of use:
During operation:
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 - 60°C/ –4°F - 140°F
Using the battery outside the above temperature
range may result in declining efficiency and shorter
battery life.
