◆If the conductive substance on human body makes contact with the exposed battery terminal,
it may damage your belongings, and/or do harm, such as burning, to human body. Conductive
material includes jewelry, keys or bead-like necklace. They can form a loop (it causes short
circuit) with battery and cause skin burn after the rapid temperature rise. Be cautious when
managing a charged battery, especially when you put it in the pocket, wallet or container with
metallic objects. To decrease the risk of being harmed, the battery cannot be exposed in the
file, disassembled or squeeze.
◆ The highest environment temperature around the power supply device or voltage
transformer must not be higher than 40°C (104°F).
◆ Please turn off the radio attached with battery when charging. Using radio during charging
will affect its charging process.
◆ Please do not put the radio and battery into the charger when they are not in need of
charging, and constant charging will shorten the battery life. Do not use the charger as a store
to radio.
◆ To achieve optimal performance, we recommend changing battery after one-year use.
