NOTICE: The above data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1 using one 18650 battery (3.7V 3400mAh) and two CR123 (3v 1700mAh) under laboratory conditions. The data may vary slightly during realworld use due to battery type, individual usage habits and environmental factors. *Runtime for Turbo mode is calculated based on theoretical arithmetic.

Operating Instruction

Battery Installation
Install batteries as shown below:

NOTE:

Main Light

ON/OFF
This product uses a two-stage power switch (similar to camera shutter). Access to its various functions depends on how hard the switch is pressed.
Turn on: When the light is off, press the power switch all the way down to turn the main light on and enter the previously used mode.
Turn off: When the light is on, press the power switch all the way down to turn the main light off.

Changing Brightness Level
When the main light is on, press the switch partway to cycle through "Ultralow-Low-Mid-High-Turbo". (The HC65 memorizes its previously used brightness level and returns to it the next time it is turned on.)

Auxiliary Lights

Auxiliary White Light
Turn on: When the light is off, press the switch partway down for over 0.6 second to turn on the auxiliary white light. Turn off: When the light is on, press the switch all the way down to turn it off.

Auxiliary Red light and Red Caution Light
Turn on: When the light is off, press the switch all the way down for over 0.6 second to turn the red light on.
Turn off: When the red light is switched on, press the switch all the way down to turn it off.
When the red light is on, press the switch partway to alternate between Red Caution Light and Red Light.

Direct Access to Turbo

• When the main light is off, press the switch all the way down twice in quick succession to enter Turbo.
• When the main light is on, press the switch partway for over 0.6 seconds to enter Turbo; press the switch partway to return the previously used mode.

Accessing Special modes (Strobe/SOS/Beacon)

When the main light or auxiliary lights are on, press the switch all the way down for over 0.6 second to turn on Strobe. After Strobe is turned on, tap the switch repeatedly to cycle through "SOS-Beacon-Strobe". Press and hold the switch all the way down to exit.

ATR (Advanced Temperature Regulation)

With Advanced Temperature Regulation module, the HC65 regulates its output and adapts to the ambient environment, maintaining optimal performance.

Positioning

When the light is off, press the switch partway to turn the position indicator on. The blue indicator beside the auxiliary light will blink once every 2 seconds to indicate its location. This serves to alert users to the location of the HC65. With the HC65 fully charged, the HC65 will remain operational for 6 months with the position indicator activated, and 12 months in standby with the position indicator deactivated. Turn the light on again to exit the positioning function.

Power Tips

Every time the battery is installed, the blue indicator 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:

Charging

• HC65 is capable of charging a protected 18650 Li-ion battery using the included USB cable. Simply loosen the tailcap and install a protected 18650 Li-ion cell, plug one end of the USB cable into the HC65's USB port and the other end into a universal USB port as shown in the adjacent image. Under normal charging conditions, the blue indicator will blink every 1.5 seconds. When charging is complete, the HC65 will automatically terminates charging, and the blue indicator will illuminate steadily. If a problem (battery damage, reverse polarity etc.) is detected, the HC65 will stop charging and the blue indicator will blink rapidly.
• Fully charging a depleted 18650 Li-ion battery takes approximately 7 hours.
• During charging, press the switch partway, the blue indicator will blink to report the voltage (refer to the power tips for detail), press the switch partway again to stop report.

Changing Batteries

Change the batteries when the output appears to be dim or unresponsive.
