This image illustrates the monocular mounted on a rifle, with icons and text pointing out features such as a high-sensitive sensor, 1024x768 HD pixels, quick image refresh, 3.2-inch full-angle TFT display, computer connectivity, and cold/hot spot automatic tracking.
Setup
Battery Installation: The device uses a rechargeable battery. Locate the battery compartment, typically at the base or side of the unit. Insert the battery according to the polarity indicators. Ensure the compartment cover is securely closed.
Lens Cap Removal: Remove the protective lens cap from the objective lens before use.
Initial Power On: Press and hold the power button (usually marked with a power symbol) for a few seconds until the display illuminates. The device may perform a brief self-check upon startup.
Eyepiece Adjustment: Adjust the eyepiece diopter to achieve a clear focus for your vision. Rotate the eyepiece until the on-screen display elements are sharp.
Operating Instructions
Power On/Off
- To power on, press and hold the power button until the screen activates.
- To power off, press and hold the power button until the device shuts down.
Focus Adjustment
Rotate the focusing wheel located on the device to bring objects into sharp focus. This is crucial for clear thermal imaging at various distances.

Color Palettes
The monocular offers 8 different color palettes to visualize thermal data. These palettes enhance contrast and highlight temperature differences, making it easier to identify targets in various environments. Common palettes include "White Hot," "Black Hot," "Red Hot," "Rainbow," and "Ultramarine." Refer to the device's on-screen menu for specific palette selection.

Image: Examples of 8 thermal color palettes. This image displays a grid of eight different thermal color schemes applied to an image of a deer, demonstrating how various palettes can emphasize different temperature ranges and improve object identification.
Detection Range
The GOYOJO CS-6 has a limit detection range of up to 2000 meters, making it suitable for observing targets at medium to long distances. The actual detection and recognition distances can vary based on environmental conditions and target size.

This video provides a visual guide to the physical features of the monocular, demonstrating its compact size, lens, and button layout. It also shows the device being used to observe a night scene, highlighting its effectiveness in dark environments and illustrating button functions for various settings.
Maintenance
Cleaning Lenses: Use a soft, lint-free cloth specifically designed for optics to clean the lenses. Avoid abrasive materials or harsh chemicals. Gently wipe the lens surface to remove dust or smudges.
General Cleaning: Wipe the body of the monocular with a damp cloth. Do not submerge the device in water, despite its IP66 waterproof rating, unless specifically designed for such use. The IP66 rating indicates protection against powerful water jets, not continuous submersion.
Storage: Store the monocular in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided protective case or bag to prevent scratches and damage.
Battery Care: If storing for extended periods, remove the battery. Recharge the battery periodically to maintain its lifespan.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or dead battery; improperly installed battery. | Charge the battery; ensure battery is correctly inserted. |
| Image is blurry or out of focus. | Improper focus adjustment; dirty lens. | Adjust the focusing wheel; clean the objective lens. |
| Thermal image appears distorted or unusual. | Extreme temperature differences; sensor calibration needed. | Allow device to acclimate to ambient temperature; perform a manual NUC (Non-Uniformity Correction) if available (refer to advanced settings). |
| Cannot capture images/videos. | Memory full; incorrect mode selected. | Delete old files or insert new memory card (if applicable); switch to photo/video mode. |
