Setup

1. Battery Installation:

   Before first use, ensure the included 18650 battery is properly installed. Remove the tailcap and insert the battery with the positive (+) end facing towards the head of the lamp. Remove any insulation paper if present.

   Fully tighten both the head and tail caps to ensure proper electrical contact and water resistance.
2. Initial Charging:

   The HS22 features a USB Type-C charging port. Connect the included charging cable to the headlamp and a USB power adapter (not included) with a 5V/2A (max) output. The indicator light will show red during charging and turn green when fully charged.

3. Headband Adjustment:

   Adjust the elastic headband to fit comfortably and securely around your head. The headlamp unit can be tilted up to 180 degrees to direct the light as needed.

Operating Instructions

The HS22 utilizes a dual-button control system for easy operation:

• Brightness Button: Controls the light intensity.
• Mode Button: Selects the beam type (Spotlight, Floodlight, Hybrid Beam).

General Operation

• Power ON/OFF: Single-click either button to turn the headlamp ON or OFF.
• Mode Selection: When ON, press and hold the Mode Button to cycle through Spotlight, Floodlight, and Hybrid Beam modes. Release to select.
• Brightness Adjustment: When ON, press and hold the Brightness Button to cycle through Eco, Low, Medium, and High brightness levels. Release to select. Double-click any button from OFF (unlocked state) to activate Turbo mode, double-click again to return to the former mode.
• Moonlight Mode: From OFF, press and hold the Brightness Button for 1 second to activate Moonlight mode.
• Color Temperature Adjustment: From ON, quickly single-click and then long-press the Brightness Button to adjust the color temperature between 3000K (warm white) and 6000K (cool white). Release to stop adjustment.
• Lock/Unlock Function: When OFF, triple-click either button to lock the HS22. The spotlight will flash twice to indicate it's locked. Triple-click again to unlock. In lock mode, any button press (except triple-click) will trigger two flashes of the spotlight to indicate the device is locked.

Battery Level Indicator

After turning on the HS22, the indicator will display the voltage for 5 seconds:

• Green Solid = 75%-100%
• Flashing Green = 50%-75%
• Red Solid = 25%-50%
• Flashing Red = 1-25%

Charging Indicator

• Red = Charging
• Green = Fully Charged

During charging, the device will automatically power off and unlock when charging is detected. While charging, it only responds to single-click operations (ON/OFF).

Maintenance

• Cleaning: Keep the lens clean and free of debris to ensure proper light output.
• Battery Care: Always remove the battery if the headlamp will not be used for an extended period to prevent potential leakage or damage.
• General Care: Do not expose the headlamp to water or extreme temperatures for prolonged periods.

Troubleshooting

• Accidental Activation: To prevent accidental activation, especially when carrying the headlamp, either loosen the tailcap slightly to physically cut off power or activate the lockout mode (triple-click any button when off).
• Heat Buildup: Extended use at high brightness levels will cause significant heat buildup. This is normal operation and not a malfunction. The temperature protection system will automatically activate if the temperature exceeds 55°C, reducing the output current to maintain an optimal outer temperature.
• Headlamp Not Turning On: Ensure the battery is correctly installed with the positive (+) end facing the head, and that both the head and tail caps are fully tightened. Check the battery level.
• Charging Issues: Ensure the USB-C cable is securely connected and the power adapter provides 5V/2A (max). The indicator should be red during charging.

Specifications

Figure 7: Detailed performance specifications for various modes and brightness levels.

Note: The above parameters are based on tests conducted in laboratory conditions (ambient temperature: 25°C) using a 4000mAh 18650 Li-ion battery. Changes in temperature, battery, and environmental factors may affect test results.

User Tips

• Optimal Beam for Task: Utilize the Spotlight mode for long-range visibility, Floodlight for wide-area illumination, and Hybrid Beam for a balanced combination. Experiment with the 180° adjustability to find the perfect angle for your activity.
• Color Temperature for Conditions: Use warmer tints (3000K) to cut through fog or haze, neutral white (4500K) for general everyday use, and cool white (6000K) for crisp, clear outdoor night vision.
• Battery Preservation: For prolonged storage, remove the battery from the headlamp. This helps prevent accidental discharge and extends battery life.

Warnings

• Do not look directly into the flashlight beam.
• Keep out of reach of children.
• Ensure the battery is installed correctly to avoid damage or leakage.
• Do not expose the flashlight to water or extreme temperatures for prolonged periods.
• Do not use rechargeable batteries that are not compatible with the flashlight.
• Always remove the batteries if the flashlight will not be used for an extended period.
• Do not point the flashlight at eyes or face.
• Keep the lens clean and free of debris to ensure proper light output.
• Extended use at high brightness will cause significant heat buildup. This is normal operation and not a malfunction.
• When carrying the flashlight, if necessary, enable the lock mode (if available) or slightly loosen the battery compartment to physically cut off the power. This prevents accidental activation and potential overheating.
