Battery and Safety

Battery and Safety Information

The Finder series is supplied with a rechargeable Li-ion Battery Pack, providing up to 6 hours of use. The battery should be charged before first use.

• Attach the USB cable to the Type C connector on the device.
• Connect the other end of the USB cable to a power adapter (rated 5V or less) or a USB socket.
• Connect the power adapter to the mains power supply.
• The LED indicator shows red when charging and turns green when charging is finished.
• When the battery icon becomes low ⚠️, it indicates the battery is low in power. Charge the device promptly to avoid reducing battery life due to over-discharge.

Safety Measures

• After long storage, charge the device partially, not fully charged or fully discharged.
• Allow the device to warm up for 30-40 minutes before charging if brought from a cold environment.
• Do not use a modified or damaged charger.
• Charge the device within a temperature range of 0°C to +40°C to maintain battery life.
• Avoid connecting third-party devices that consume excessive power.
• The equipment has a short circuit protection system; however, situations that may lead to short circuits should be avoided.
• The recommended operating temperature for the device is between -10°C and +50°C. Exceeding this range may shorten battery life.
• Battery capacity may drop in sub-zero temperatures; this is normal and not a defect.
