Thanks for purchasing NITECORE!

Output & Runtime

NOTICE

The above data has been measured in accordance with the international 

flashlight testing standards ANSI/NEMA FL1 using the NItecore NBP52 battery 

pack under laboratory conditions. The data may vary during real-world use 

due to battery type, individual usage habits and environmental factors.

Lockout/Unlock

With the light turned on, press and hold the switch for more than one 
second until the flashlight is switched off and enters into lockout mode. 
Lockout mode consumes almost no battery power and prevents 
accidental activation of the flashlight. To exit lockout mode, simply press 
and hold the switch for more than one second again.

NOTE: 

1. In lockout mode, the OLED display will show “LOCK OUT” as a 
reminder when the switch or the display button is pressed.
2. When TM36 is kept in a backpack or left unused for extended periods, 
Nitecore recommends users loosen the bezel to cut off power, thus 
saving battery power and preventing accidental activation of the 
flashlight.

Power Tips

1. With the light switched on, the power indicator will blink once every two 

seconds when power levels drop to 50%.

2. With the light switched on, the power indicator will blink rapidly when 

power levels are low.

NOTE: 

When the light is being used in ultra-low mode, the blue power 

indicator will be off to help conserve power.

Thermal protection

Extended operation in Turbo mode will cause the tube temperature of 
TM36 to continually rise, making it too scalding to hold. Thus, Nitecore 
does not recommend using the TM36 in Turbo mode for extended 
periods. Equipped with an integrated thermal protection circuit, the TM36 
will automatically reduce its output to prevent overheating once tube 
temperature has reached 60 degrees.

Precaution: 

When tube temperature is high, do not attempt to cool it by 

submerging it in liquid. This faulty operation may cause irreparable 
damage to the TM36 due to air pressure difference inside and outside of 
the tube.

Charging Battery Pack

Battery pack should be replaced or recharged when any of the following 
occurs: The power indicator blinks rapidly, output appears to be dim or 
the flashlight becomes unresponsive. 

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by a 
thin coating of silicon-based lubricant.

TM 36

NITECORE (SYSMAX)

 is a member of PLATO, participating in and helping to 

develop the ANSI FL1 standard of measurement. Product testing data is in 
accordance with these internationally recognized scientific standards.

Charging the TM36

Connect the charging cable to the flashlight and the A/C power adapter to the 
wall outlet as shown in the adjacent image. 

General Operation

NOTE:

 The TM36 utilizes a 2-stage switch similar to a camera shutter button. 

The light’s numerous functions are selected according to the depth the switch 
is pressed.
The TM36 has two modes: Daily mode and Turbo mode. With the TM36 turned 
off, press the switch partway down and release quickly to activate Daily mode. 
Alternatively, with the TM36 turned off, press the switch all the way down and 
release quickly to activate turbo mode.

Mode Selection 

Daily mode: 

With the light off, press the switch partway down and release 

within one second to enter this mode with constant-on illumination; press and 
hold the switch partway down to activate momentary illumination with previous 
daily mode brightness. 

Turbo mode: 

press the switch all the way down and release within one second 

to enter this mode with constant-on illumination; press and hold the switch all 
the way down for more than one second to activate momentary illumination 
with max brightness. 

OLED Display

1. When the TM36 is turned on, the OLED display will activate automatically 
and show output lumen, brightness mode, battery voltage, battery status, 
remaining runtime and temperature. After displaying these readings, the OLED 
display will be off automatically. To reactivate the OLED, simply press the 
display switch. To cycle through the readings, press the display button in 
sequence.
2. When in standby mode, a single press of the OLED display switch will 
activate the OLED and display battery voltage for 10 seconds.

Brightness Selection In Daily Mode

1. With the TM36 turned on in Daily mode, press the switch partway down to 
select a brightness level of ultra-low, low, medium or high. The selected 
brightness level will be memorized when the light is turned off.
2. With the TM36 turned on in Daily mode, press the switch partway down and 
hold to enter into turbo mode. A second partway press will revert back to the 
brightness level last used.

Bright Selection In Turbo Mode

With the TM36 turned on in Search/Turbo mode, partway presses of the button 
will cycle between high and ultra-high mode. Memory function is not available 
in Search/Turbo mode.

NOTE: 

In turbo mode, the thermal protection will activate. Please refer to 

Thermal Protection. 

Standby Mode

With the TM36 turned on, press the switch all the way down and release within 
one second to enter into standby mode. In this mode, the light will consume 
small amounts of power to maintain the settings in the MCU (micro control unit) 
while appear to be turned off. When in standby mode the power indicator light 
will blink once every two seconds to indicate the location of the light.

Special Modes (Strobe / SOS / Location 

Beacon)

With the light turned on, press the switch all the way down twice in quick 
succession to access strobe mode. When in strobe mode, press the switch 
partway down to cycle through SOS, location beacon and strobe modes. To 
select a desired mode, simply release the switch when it is displayed. To exit 
the special mode (enter into standby mode) fully press and release the switch.

NOTE: 

When in any of the special modes, the OLED display will remain on to 

display the specific mode being used.

Demonstration mode

When entering standby mode, press the switch with the display button being 
held simultaneously to enter Demonstration mode. In this mode, the OLED 
display will present TM36’s functioning messages in a consecutive manner. To 
exit Demonstration mode, simply press any button.

1. Under normal charging conditions, the on/off switch’s blue indicator light will 
blink twice every second with the OLED screen display "Charging..." and 
battery voltage.
2. If a problem is detected while charging the TM36 will stop charging, the blue 
indicator will blink rapidly and the OLED display will show the word “ERROR”. 
This is usually caused by faulty or incorrectly inserted batteries. 
3. When charging is complete, the blue indicator will remain on, 
and“Chg.Finished” along with battery voltage will be displayed on the OLED 
screen.

The NBP52 battery pack can also be recharged independently. As shown, plug 
one end of the adapter to the battery pack charging port (1A, 3.5mm), and plug 
the other end to an outlet.  

The integral blue charging indicator of NBP52 battery pack will blink to indicate 
charging process:
1. When battery pack is being recharging, the blue indicator will blink rapidly.
2. When battery power level reaches 98%, the blue indicator will blink slowly.
3. When battery pack is fully charged, the blue indicator will illuminate steadily.

NOTE: 

1. Charging the flashlight or the battery pack directly will require charging time 
of approximately 16 hours.
2. Charging time can be reduced by half to 8 hours if the NBP52 battery pack is 
recharged via the rapid charging port (2A, 4.5mm) using an optional 2A 
adapter.
