Tube series thermal imagers are infrared scopes for outdoor hunting. Designed based on infrared thermal imaging principles, they require no external light sources during the day and at night, in all hard weather conditions (such as rain, snow, fog, and haze). They can be used without being affected by strong light and to observe even targets behind obstacles (such as branches, grass, and shrubs). The Tube series has a variety of battery-powered solutions with long operating hours, and can be widely used for hunting, observation and positioning in low visibility conditions. It adopts a 30mm standard pipe diameter to meet the requirements of the general clamp interface. III. Product Features 12m self-developed detector;

(built-in chargeable Lithium-ion battery pack and a replaceable 18500 battery). The normal working time of the dual power supply system can be up to 11.5 hours. The battery should be fully charged before first use. Charging the Built-in Battery Package Turn counterclockwise to open the USB cap;

Insert the Type-C end of the attached data cable into the Type-C socket on the Tube;

Connect the other end of the data cable to the power adapter, and insert the adapter into a 100-240V power socket to charge the battery pack;

During charging, a lightning charging icon appears on the right of the battery icon, and the LED indicator on the device is in red. When the indicator turns green, it indicates that charging is complete. 11th Guiyang Street, YEDA, Yantai 264006, P.R. China

+86-400-998-3088 During use, if the battery icon turns to

, it indicates that the battery level is low. Please charge the battery in time to avoid reducing the service life of the device due to over discharge of the battery. Note: The USB port can only be used for charging the built-in battery pack. Installing 18500 battery Turn anticlockwise to open the battery holder cover (11);

Install the 18500 battery (12) according to the indication label in the battery holder, that is, the positive pole faces inward and the negative pole faces outward;

Close the battery holder cover (11) and turn clockwise to tighten it. Safety Measures When charging, please use the 5V2A power adapter compatible with the device. Using any other type of adapter may cause irreversible damage to the battery or the adapter itself;

If the device is not in use for a long time, the battery should be partially charged, not fully charged or discharged. Do not charge the device immediately after it is moved to a warm environment from a cold environment. Wait for 30 to 40 minutes for preheating. If the charger is modified or damaged, do not use it;

The device should be charged at a temperature of 0C to +40C. Otherwise, the battery life will be significantly reduced. When charging, please do not leave the battery unattended;

Do not connect the battery to the power supply for more than 24 hours after it is already 11th Guiyang Street, YEDA, Yantai 264006, P.R. China

allowed value. It is not recommended to connect third-party devices that consume more energy than the The device is equipped with a short circuit protection system, but conditions that may lead to a short circuit should be avoided. The recommended operating temperature for the device is -20C to +50C. Do not use the device beyond this temperature range, or else, it may shorten the battery life. When the device is used under sub-zero temperature, the battery capacity drops. This is normal and does not indicate a defect. Switching between two types of batteries The Tube series supports the dual power supply system: built-in Lithium-ion battery pack and replaceable 18500 battery, while supporting a USB power supply. If both batteries are installed in the Tube device, two battery icons are displayed on the right of the status bar below the image, with the replaceable battery icon on the left and the built-in battery icon on the right. Green indicates that the device is being powered, and gray indicates that the device is not powered on. If the replaceable battery is not installed, only the built-in battery icon is displayed in the lower right corner. If the replaceable battery is installed and fully charged, it will be preferred. When the replaceable battery is low, the device will switch to the built-in battery automatically. When the device is connected to a USB, it will switch to the external power supply USB automatically. At this time, a lightning charging icon is displayed on the right of the built-in battery icon

, which indicates that the built-in battery is being charged. When the device is in use, the replaceable battery can also be replaced. At this time, it will switch to the internal battery automatically. 11th Guiyang Street, YEDA, Yantai 264006, P.R. China

Then, the device automatically switches to the external power supply and charge the internal battery pack at the same time;

When the external power supply is turned off, the device switches to the replaceable 18500 battery for power supply. If no replaceable 18500 battery is installed or the battery level is low, it will switch to the built-in battery pack, instead of shutdown. VIII. Installation and Usage Fixed installation WARNING! The lens of the device must not be pointed at any sources of intense radiation 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. To ensure firing accuracy, please fix the Tube at a proper position on the weapon. The Tube series needs to be fixed with an adapter clamp, such as a simple Picatinny rail clamp provided in the package. The Tube series adopts a tubular body design with a diameter of 30mm, which is compatible with standard clamps with a diameter of 30mm, such as those of day scope. Proper tools can be used to install the Tube device according to the supplier's installation suggestions and steps. During installation, the installation position of the Tube device should be adjusted according to the distance between eye and eyepiece (eye relief) as specified in the specifications and the sense of use and comfort. If you fail to follow this suggestion, the eyepiece may hurt the shooter during the shooting. It is recommended to install the scope as low as possible, but keep it away from the barrel or other devices;

Use the supplied torque wrench to tighten the screws of the installation clamps;

When the scope is used for hunting, please carry out the zeroing operation first according to the instructions as specified in Chapter IX "Zeroing" in this manual;

When using the scope at night or in a dark environment, it is recommended to use an eye 11th Guiyang Street, YEDA, Yantai 264006, P.R. China

The device is beyond Wi-Fi coverage. There is blocking (such as concrete walls) between the device and the receiver. The observed target You are observing the target Observe the target directly without the disappears through the glass presence of glass The image quality is poor or the detection range shortens When the device is used at a low temperature, the imaging quality is poorer than that at normal temperature. These problems are likely to occur when you use the device in harsh weather (such as snow, rain, and fog). At temperatures above 0C, the temperature rise varies with the observed objects (environment and background) due to different heat conductivity coefficients. As a result, high-temperature contrast occurs and the image quality is better. At low temperatures, the observed targets (background) usually cool down to a similar temperature because of reduced temperature contrast. Therefore, the image quality (details in particular) is poor, which is a characteristic of thermal imaging devices.
