(3,500mAh) under laboratory conditions. The data may vary in real-world use
due to different battery usage or environmental conditions. * The runtime for
TURBO mode is tested with fan cooling, as a simulation of the trail running
environment.

Operating Instructions
Battery Installation
Insert the battery(s) as illustrated and screw to tighten the tail cap.
Note: After the battery insertion, the LEDs will flash to indicate the
battery voltage. Please refer to the “Power Indication” section of this manual
for more details.
Warnings:
- Ensure the battery(s) is/are inserted with the positive end towards the head. The product will not work if the battery(s) is/are incorrectly inserted.
- CAUTION! Possible dangerous radiation! Don’t look into the light! Maybe dangerous for your eyes.
- When the product is kept in a backpack or left unused for a prolonged time, please remove all batteries to prevent accidental activation or battery leakage.
On/Off
The UT32 has dual power buttons for independently controlling the two beams as
illustrated. (Button A is designed with a bump in the center.)
On: When the light is off, long press both buttons to turn it on and
access the LOW level of the Cool White Beam.
Off: When the light is on, long press both buttons to turn it off.
Beam Switching
When any brightness level or special mode of the Cool White Beam is on, short
press Button B to switch to the corresponding brightness level or special mode
of the Warm White Beam.
When any brightness level or special mode of the Warm White Beam is on, short
press Button A to switch to the corresponding brightness level or special mode
of the Cool White Beam.
(Note: Both beams cannot be turned on at the same time.)
Brightness Levels
Cool White Beam: When the Cool White Beam is on, short press Button A
to cycle through the following brightness levels of the Cool White Beam: LOW —
MID — HIGH.
Warm White Beam: When the Warm White Beam is on, short press Button B to
cycle through the following brightness levels of the Warm White Beam: LOW —
MID — HIGH.
TURBO Activation
Search Mode: The headlamp will automatically return to the previous brightness level after accessing TURBO for 30 seconds when using this access, suitable for signpost searching.
- When the Cool White Beam is on, long press Button A to access TURBO of the Cool White Beam.
- When the Warm White Beam is on, long press Button B to access TURBO of the Warm White Beam. Constant-on Mode: When the light is off, long press both buttons to access TURBO of the Cool White Beam after accessing LOW of the Cool White Beam. You will need to exit TURBO manually when using this access.
Special Modes (SOS / BEACON)
Cool White Beam: When the light is off, triple press Button A to access
the SOS Mode of the Cool White Beam. When the SOS Mode is on, short press
Button A to switch between the BEACON and SOS modes. Long press Button A or
both buttons to exit special modes and turn off the light.
Warm White Beam: When the light is off, triple press Button B to access
the SOS Mode of the Warm White Beam. When the SOS Mode is on, short press
Button B to switch between the BEACON and SOS modes. Long press Button B or
both buttons to exit special modes and turn off the light.
Power Indication
When the battery is inserted and the tail cap is tightened, the LEDs will flash to show the battery voltage (±0.1V). For example, when the battery voltage is at 4.2V, the power indicator will flash 4 times followed by a 1.5-second pause and 2 more flashes. The headlamp will be turned off after this process. Different voltages represent the corresponding remaining battery power levels:
Note:
- When using two CR123/RCR123 in series, the LEDs will show the average voltage between the two
- If it fails to display the voltage correctly, please press and hold both buttons for over 1 second with the tail cap loosened to ensure the headlamp is totally power off, and then tighten the tail cap
ATR (Advanced Temperature Regulation)
The integrated ATR technology regulates the output of the UT32 according to
the working condition and ambient environment to maintain optimal performance.

the working condition and ambient environment to maintain the optimal
performance.
Changing Batteries
The batteries should be replaced when the output appears to be dim or the
headlamp becomes unresponsive due to low power.
Maintenance
Every 6 months, threads should be wiped with a clean cloth followed by a
thin coating of silicone-based lubricant.
