Regulatory Information
Companies, businesses, or users are not permitted to change the frequency, increase the transmitting power, or alter the original characteristics and performance of approved low-power radio frequency devices without prior authorization from the NCC.
Low-power radio frequency devices shall not affect flight safety or interfere with legal communications. If interference is detected, users must immediately cease operation until the interference is resolved.
Legal communications refer to radio communications operated in accordance with the Telecommunications Management Act. Low-power radio frequency devices must tolerate interference from legal communications or from ISM (Industrial, Scientific, and Medical) radio wave radiation devices.
Do not place the device in a confined space, such as a bookshelf or built-in cabinet.
Do not expose batteries (battery pack or installed batteries) to excessive heat such as direct sunlight, fire, or similar sources for extended periods.
Do not expose batteries to extremely low air pressure, as this may result in overheating or leakage.
Do not disassemble, open, or cut secondary batteries.
In case of secondary battery leakage, prevent liquid from contacting skin or eyes. If contact occurs, wash the affected area with plenty of water and seek medical attention.
Charge secondary batteries before use. Refer to the manufacturer's instructions or product manual for proper charging methods.
After prolonged storage, secondary batteries may require several charge/discharge cycles to achieve maximum performance.
Dispose of properly.
Charging the Device
