The main controls are arranged so that frequently used functions can be accessed directly from the buttons without repeatedly entering the menu.

1
Power on

Insert a charged 18650 battery and hold the Power button for approximately 3 seconds to switch the device on or off.

2
Focus and dioptre

First adjust the dioptre until the interface is clear, then adjust objective focus according to the observed subject.

3
Change image mode

A short press of the Menu button changes the main image modes, while a long press opens the menu.

4
Zoom and LRF

A short press of the lower navigation button changes magnification, while holding it activates the laser rangefinder.

5
Photos and video

The device allows direct image capture and video recording through the controls on the housing.

6
Wi-Fi connection

Enable Wi-Fi from the menu and connect the device to a compatible Falcon mobile application.

Do not point the thermal sensor at the Sun, CO₂ lasers, welding arcs or other intense radiation sources for prolonged periods. Remove the battery for long-term storage.
Observation Scenarios
For observing wildlife, terrain and large open areas

The combination of a 640×512 sensor, 35 mm lens, 2× base magnification and integrated rangefinder makes the S1-635L a versatile handheld thermal device for observing both open and mixed terrain.
