2BTL3-SOFTLIGHTContact Fill Light

Contact Fill Light User Manual Thank you for choosing this Bluetooth fill light! To help you use the product better and fully unleash its functions, please read this manual carefully before use and keep it properly for future reference. I. Product Overview 1.1 Product Introduction This Bluetooth fill light is a multi-functional device integrating lighting and intelligent control. It can be connected to a mobile phone APP via Bluetooth technology to achieve various lighting effect adjustments, suitable for live streaming, shooting, video conferences, beauty fill lighting, and other scenarios. 1.2 Product Parameters  Input Voltage: 5V/1A  Battery Capacity: 2000mAh  Battery Life: Approximately 8 hours at minimum brightness, approximately 2 hours at maximum brightness  Color Temperature Range: 2700K - 6500K  Brightness Adjustment: 1%-100% stepless dimming 1.3 Product Accessories  1 × Bluetooth fill light  1 × USB-C charging cable  1 × User manual II. Usage Instructions 2.1 Power On and Off Long-press the power button on the back of the fill light for 2 seconds to turn it on. The default brightness is 50%, and the color temperature is 4000K. Long-press the power button again for 2 seconds to turn it off. 2.2 Brightness Adjustment Short-press the power button to switch brightness. Each press increases the brightness by 10% (10%→20%→...→100%). When reaching 100%, pressing again resets the brightness to 10%. Stepless dimming from 1% to 100% can also be achieved via the mobile phone APP for more precise operation. 2.3 Color Temperature Adjustment Double-press the power button to switch color temperatures, cycling through warm light (2700K), natural light (4000K), and cold light (6500K). Similarly, fine-tuning of color temperature can be realized on the mobile phone APP to meet lighting needs in different scenarios. 2.4 Bluetooth Connection and APP Control 1. Turn on the fill light and ensure it is in the power-on state. 2. Find the name of your Bluetooth fill light in the device list and click to connect. 3. After successful connection, you can freely set the fill light's brightness, color temperature, and lighting modes (such as gradient, flashing, breathing light, etc.) on the APP interface. You can also create and save personalized lighting schemes for quick recall next time. 4. 2.5 Bracket Usage Open the clip at the bottom of the foldable bracket, clamp it onto a suitable position such as a mobile phone, tablet, or desktop, then install the fill light into the slot at the top of the bracket. Adjust the angle and height of the bracket to find the optimal fill light position. III. Charging Instructions 1. When the fill light's battery is low, the indicator light will turn red and flash, requiring immediate charging. 2. Use the included USB-C charging cable to connect one end to the fill light's charging port and the other end to a power supply device such as a computer USB port, 5V/1A charger, or power bank. 3. During charging, the indicator light remains red; when fully charged, the indicator light turns green. The charging time is approximately 2-3 hours. 4. To ensure battery life, do not overcharge or allow the battery to drain completely. It is recommended to charge when the remaining battery is about 20%. IV. Maintenance and Care 1. When cleaning the fill light, turn off the power and disconnect the charging cable first. Gently wipe it with a clean, soft damp cloth. Avoid using corrosive cleaners such as alcohol or gasoline. 2. When not using the fill light for a long time, store it with a full charge and perform a charge-discharge cycle every month to prevent battery aging. 3. Avoid exposing the fill light to high-temperature, humid, or dusty environments to prevent affecting product performance and service life. 4. Do not disassemble the fill light privately. In case of a fault, contact after-sales service personnel for handling. V. Safety Precautions 1. Do not place the fill light near flammable or explosive items to avoid danger. 2. Do not let children use the fill light alone to prevent accidental swallowing of small parts or equipment damage caused by improper operation. 3. If the fill light smokes, emits an unusual odor, or overheats, stop using it immediately, disconnect the power, and contact after-sales service. 4. This product is for indoor use only. Do not use it in rain or humid environments. VI. Common Problems and Solutions Problem Phenomenon Possible Cause Solution The fill light fails to power on Battery exhausted or power button malfunction Connect to a charger and try powering on again; if the problem persists, contact after-sales service Bluetooth fails to connect Fill light Bluetooth not enabled, excessive distance, or outdated APP version Ensure the fill light is powered on and in a connectable state, keep the mobile phone and fill light within 10 meters, and update the APP to the latest version Unstable Low battery or poor Charge in a timely manner; Problem Phenomenon Possible Cause Solution light flickering contact check if the charging cable and interface are firmly connected, and re-plug if loose APP cannot control the fill light Bluetooth connection interrupted or APP abnormality Reconnect the fill light in the APP; close and reopen the APP.

FCC ID: 2BTL3-SOFTLIGHT RF Exposure Evaluation According to KDB 447498 D01 General RF Exposure Guidance v06 and part 2.1093，Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison Here, The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.
