NOTE: The above data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1, using 1xIMR 18650 battery (3100mAh) under laboratory conditions. The data may vary in real-world use due to different battery use or environmental conditions.

The runtime for Turbo or High mode is the testing result before starting temperature
regulation.

The Turbo 1800 lumens requires the use of rechargeable IMR18650 or 18650 Li- ion batteries with output current higher than 8A. The Turbo is not accessible with CR123A or RCR123A batteries.

Operating Instructions

Battery Installation
As illustrated, insert batteries with the positive (+) end facing towards the head.

Warning

1. Ensure batteries are inserted with the positive (+) end pointing to the head. The HC33 will not operate with incorrectly inserted batteries.
2. CAUTION! Possible dangerous radiation! Don’t look into the light! Maybe dangerous for your eyes.
3. When the power level of IMR18650 Li-ion battery is low, please stop using and recharge the battery.
4. When the HC33 is kept in a backpack, please loosen the tailcap to prevent accidental activation of the flashlight; When the HC33 is left unused for extended periods of time, please remove all batteries to prevent battery leakage.
5. Do not submerge the product in water or any liquid when it has generated sufficient heat, doing so will cause pressure inequalities and significantly increase risk of water damages.
6. The product contains strong magnetic components. DO NOT put it close to objects that tend to suffer from magnetic interference (e.g. bank cards, watches and medical equipment).

ON/OFF

• Turn on: When the light is off, press the switch for 0.6 seconds to turn on the light.
• Turn off: When the light is on, press the switch for 0.6 seconds to turn off the light
• Instant Ultralow: With the HC33 is switched off, tap the switch to enter ultralow mode.
• Instant Turbo: With the HC33 is switched off, press the switch for about 1.5 seconds to enter turbo mode.

Adjusting Brightness Levels
With the HC33 is switched on, press the switch repeatedly to cycle through brightness levels of Ultralow-Low-Middle-High-Turbo. (Brightness levels can be memorized)

Special modes (Strobe/SOS/Beacon)
When the light is off, quickly tap the headlamp switch twice to enter Strobe. After Strobe is turned on, tap the switch repeatedly to cycle through SOS- Beacon-Strobe. Turn off the light to exit. (Special modes can not be memorized)

ATR (Advanced Temperature Regulation)
With Advanced Temperature Regulation module, the HC33 regulates its output and adapts to the ambient environment, maintaining optimal performance.

Power Tips
When power is off, every time the battery is installed, tighten the head and tail cap, the light will report battery voltage (to the nearest ±0.1V) For example, when the battery voltage is at a maximum charge of 4.2V, the power indicator will blink 4 times, followed by 1.5 seconds pause and 2 more blinks before entering the standby status.

Different voltages represent the corresponding remaining battery power levels:

Note:

1. when using two CR123/RCR123 in series, the flashlight only reports the average voltage of the two batteries.
2. If it can not report the voltage normally, please loosen the tail cap first, then press the switch for 1 second to ensure the HC33 is power off thoroughly and then tighten the tail cap.

Changing Batteries
Recharge the batteries when the output appears to be dim or the brightness levels can not be selected normally.

Maintenance
Every 6 months, wipe the threads of the battery case with a clean cloth followed by applying a thin coating of silicon-based lubricant.
