between -10’C and +50’C. Do not use the product beyond this temperature range — this may shorten battery life. When the device is used in sub-zero temperatures, the battery capacity drops., this is normal and does not indicate a defect.

OPERATION

ATTENTION! The lens of the device must not be pointed at any sources of intense energy, such as laser-emitting devices or the sun. This may damage the electronic components in the device. Damage caused by failure to comply with the operating guidelines is not covered under warranty.

ower on and image adjustment

Remove the lens cap.
Long pressing the Power(6) button for 2 seconds to power on. Waiting for 3 seconds to enter the main interface.
Adjust the resolution of the icons on the display by rotating the diopter adjustment ring on the eyepiece.
To focus on the object being observed, rotate the lens focus ring.
Adjustment of display brightness, image mode and sharpness, as well as turning on the smooth digital zoom, are described in the SHORTCUT MENU FUNCTIONS section.

Detail as follows: Upper left corner–Color palette, magnification, calibration mode, Wi-Fi (on), Automatic screen off (on); Upper right corner–Battery level; Lower left corner–Time and date; Lower right corner–Video output icon (on).

The color of the battery icon represents the current battery level. When the battery icon is shown in red, it indicates that the battery is low. Please charge it in time.

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 (Ml and automatic (A). Select the required mode in the CALIBRATION section of the MAIN MENU.

M mode (manual). The device needs to be calibrated manually.
- For FL25R/FH25R- short press the Up (4)+Down (3) button for shutter calibration, and long press for background calibration.
- For FL25/FH25- short press the Up (4) button for shutter calibration, and long press for background calibration
- The lens cap should be closed for background calibration.
A mode (automalic).The device is calibrated autonomously by the software algorithm. The lens cap need not be secured (the sensor is closed by an internal shutter).

Note
Manual shutter calibration and manual background calibration are still possible even in mode A.

Finder Series thermal imager is equipped with a function for video recording and photographing an observed image onto the built-in memory card.
