Safety Measures

Use this battery charger to charge the battery pack only. Otherwise it will cause irreparable damage to the battery pack or charger and even may cause fire.
Before a long storage time, the battery pack should be partially charged, not fully charged or discharged.
Do not charge the battery immediately after you bring it from the cold to the warm. Wait 30 to 40 minutes for it to warm up.
Do not use the charger if it is modified or damaged.
The device should be charged at a temperature of 0°C – +45°C. Otherwise the battery life will be significantly reduced.
When charging, please don’t leave the battery unattended.
Do not expose the battery to high temperature or open flame.
Do not immerse the battery in water.
The battery pack has short circuit protection. But situations that may lead to short circuits should be avoided.
Do not charge the battery for more than 24 hours after it is already fully charged.
It is not recommended to connect third-party devices that consume more power than allowed.
Do not disassemble or modify the battery pack without professional instructions. Do not knock or drop the battery pack.
The recommended operating temperature for the device is -20°C – +50°C. Do not use the device beyond this temperature range, which may shorten the battery life.
When the device is used under sub-zero temperature, the battery capacity drops, which is normal and does not indicate a defect.
Please keep the battery pack out of the reach of children.

EXTERNAL POWER SUPPLY
Finder II series supports external power supply, such as the portable power source (5V).

Connect the external power supply to the Type-C port (13) of the device.
The device will automatically switch to the external power supply and charge the battery pack (8) at the same time.
At this time, the battery icon on the display will become to the charging icon CD and the power indicator will turn red, and then turn green after the battery is fully charged.
If an external power supply is connected, but no battery pack is installed, the battery icon will become a U513 icon Be and the power indicator will turn green.
When the external power supply is disconnected, Finder II series will automatically switch to the battery pack power supply and will not shut down.

CALIBRATING THE SENSOR
When the image is degraded or uneven, it can be improved by calibration. Calibration enables the detector temperature background to be equalized and defects in the image to be eliminated. There are two calibration modes: manual calibration (M) and automatic calibration (A). Select the required mode in the CALIBRATION section of the MAIN MENU:

A mode (autornatic).The device is calibrated autonomously by the software algorithm. The lens cap need not be secured (the sensor is dosed by an internal shutter).
M mode (manual). The device needs to be calibrated manually. > Short press the Up (5)+Down (6) button for shutter calibration, and long press for background calibration. > The lens cap should be closed for background calibration.
Note Manual shutter calibration and manual background calibration are still possible even in mode A.

PHOTOGRAPHING AND VIDEO RECORDING
Finder II Series thermal imager is equipped with a function for video recording and photographing an observed image onto the built-in memory card. The files of images and videos will be named after the time, so it is recommended to reset the system time in the Main Menu or to synchronize the system time and date in the Settings of the APP before using the photo and video function. For specific operations, you can download the operating instructions of the APP from the company’s website.
