4. Do not mix batteries of different charge levels.

5. Do not use lithium batteries without a protected circuit board.

6. This product does not support 18650 rechargeable Li-ion 

batteries without protection circuit board as the battery length will 

be too short to be used.

General Operation

NB:

 The TM11 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 TM11 has two modes: Daily mode and Turbo mode. 
With the light turned off:

·

Press the switch partway down and hold to enter Momentary Daily 

mode. Release the switch to turn the light off again.

·

Press the switch all the way down and hold to enter into 

Momentary Turbo mode. Release the switch to turn the light off 
again. 

·

Press the switch partway down and release within one second to 

access Constant Output Daily mode. Press switch to turn light off 
again.

·

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

to access Constant Turbo mode. Press switch to turn light off 
again.

Thanks for purchasing NITECORE!

Standby Mode / Lockout and Unlock functions

With the light 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) but appear to 
be turned off. When in standby mode the power indicator light will flash once 
every three seconds to show the location of the light. 
With the light turned on:
Press the switch all the way down and hold for more than one second. The 
light will turn off and enter into lockout mode. Lockout mode consumes 
almost no battery power and prevents the light from accidentally turning on. 
To exit the lockout mode, simply press the switch three times within one 
second.

NB:

 When in lockout mode, the power indicator will flash to indicate specific 

battery voltage. Please refer to the “Power Tips” section of this manual 
for details.

Brightness Selection in Daily Mode

When turned on in Daily mode, press the switch partway down to select a 
brightness level of low, medium or high. The selected brightness level will be 
memorized when the light is turned off.

Strobe Function

With the light turned on, press the switch all the way down twice in quick 
succession to access strobe mode. Press once again to exit the strobe 
mode.

NOTICE

Stated data has been measured according to the international flashlight 

testing standards ANSI/NEMA FL1 by using eight SYSMAX CR123 batteries 

in the laboratory. The data may vary due to different battery usage and 

environment conditions.

Operation instructions

Battery installation

Insert 4 × 18650 Li-ion or 8 × CR123 batteries with the positive (+) end 

pointing toward the flashlight head. In special circumstances, such as an 

emergency situations, one to three 18650 Li-ion or two to six (R) CR123 

batteries may be used. After loading the batteries, the power indicator light 

will flicker to show the battery voltage. Please refer to the “Power Tips” 

section of this manual for details.

Output & Runtime

Note:

 

The potential risks of over-discharging batteries can include 

leakage and explosion so caution must be exercised when 

using less than 4 x 18650 or 8 x CR123. Ensure you know 

your batteries’ limits and use the TM11’s emergency 

functionality sparingly. Furthermore, maximum output may be 

reduced when using less than the maximum amount of 

batteries. 

Power Tips

1. When the light is on, the power indicator will blink once every two seconds 

when power levels reach 50%.

2. When the light is on, the power indicator will flicker constantly when power 

is very low.

3. Each time batteries are inserted or the light is put into lockout mode, the 

power indicator light will blink in various patterns to show the battery 
voltage (accurate to ±0.1V). For example, when the battery voltage is at a 
maximum charge of 4.2V, the power indicator will blink 4 times in quick 
succession, followed by a one second pause and two more blinks, 
indicating a total battery voltage of 4.2V.

Thermal protection 

TM11 is very compact. Extended operation in Turbo mode will cause the 
body temperature to continually rise, thus, making it too hot to use. So 
NITECORE does not recommend using the TM11 in Turbo mode for 
extended periods. TM11 built-in thermal protection circuit prevents 
overheating. For your safety and to protect the flashlight from failure, the 
TM11 will automatically reduce its output to prevent overheating once it has 
reached 60 degrees. 

Precaution: 

When the flashlight is hot, do not attempt to cool it by 
submerging it in liquid.

Changing batteries

When the power indicator blinks consistently it means the batteries need to 
be replaced or recharged. Alternatively if the light becomes dim or 
unresponsive to adjustments once again, the batteries need to be replaced 
or recharged.

Maintenance

Clean the threads twice a year with a clean soft cloth and apply thin 
coat of silicone-based lubricant.
