Operation instructions

Battery installation

Unscrew the tailcap, insert 4 × 18650 Li-ion or 8 × CR123 batteries with the positive (+) end pointing toward the flashlight head. Replace the tailcap. In special circumstances, such as emergency situations, between one and three 18650 Li-ion or two and six CR123 batteries may be used.

Note 1: Due to the strain using less than 4 x 18650 or 8 CR123 places on

batteries, Nitecore recommends using this feature only when necessary and for short periods of time. Please see point number 1 in the warning below.

Note 2: After loading batteries, “NITECORE” will be displayed on the OLED

screen for 2.5 seconds followed by battery voltage (accurate to

0.01V) after which the TM26 will enter into standby mode.

WARNING

1. Using less than 4 x 18650 or 8 x CR123 batteries can lead to turbo mode malfunctioning, can trigger the overload protection circuit in Li-ion batteries and can even lead to explosion of CR123 batteries. As such Nitecore recommends this function is used with caution and only when necessary.

2. Insert batteries with the positive (+) end pointing toward the flashlight head.

3. Do not mix rechargeable and non-rechargeable batteries.

4. Do not mix batteries of different types/brands.

5. Do not mix batteries of different charge levels.

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

7. This product does not support unprotected 18650 Li-ion batteries. Please also ensure that all the 18650 batteries used in the TM26 have a button top configuration or they will not make contact with terminals in the battery compartment. We recommend Nitecore 18650 batteries for the best performance and reliability.

Charging the TM26

1. Connect the charging cable to the flashlight and the A/C power adapter to

the wall outlet as shown in the adjacent image. Fully charging four depleted

18650 batteries takes approximately 7 hours.

2. Under normal charging conditions, the on/off switch’s blue indicator light will

blink twice every second and the OLED screen with display the word

‘Charging...” together with battery voltage.

3. If a problem is detected while charging the TM26 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.

4. When charging is complete, the blue indicator will remain on, and

“CHG.FINISHED” along with battery voltage will be displayed on the OLED

screen.

General Operation

NB: The TM26 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 TM26 has two modes: Daily mode and Turbo mode. With the TM26 turned

off, pressing the switch partway down will activate Daily mode. Alternatively,

with the TM26 turned off, pressing the switch all the way down will activate

turbo mode. The TM26 is turned off by pressing the switch all the way down.

Brightness Selection In Daily Mode

1. With the TM26 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 TM26 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 TM26 turned on in Search/Turbo mode, partway presses of the button

will cycle between high and ultra-high mode. There is no memory function in

Search/Turbo mode.

Momentary Daily / Turbo Mode

1. With the TM26 turned off, press the switch partway down and hold to

activate Momentary Daily mode. Release the switch to turn the light off

again.

2. With the TM26 turned off, press the switch all the way down and hold to

enter into Momentary Turbo mode. Release the switch to turn the light off

again.

Standby Mode

With the TM26 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.

OLED Display

1. When the TM26 is turned on, the OLED display will activate automatically

and show lumen output, brightness mode, battery voltage, battery status,

approximate runtime and temperature. After displaying this information for

several seconds the OLED display will turn off. The display can be

reactivated by pressing the display switch and the information can be cycled

through with subsequent presses of the switch.

2. When in Standby mode, a single press of the OLED display switch will

activate the OLED and display battery voltage for 10 seconds.

3. When using Nitecore’s NBP52 high-performance battery pack, the actual

runtime will be twice the figure displayed on the OLED panel.

NB: The TM26 has an integrated thermal protection circuit which prevents

overheating. Please refer to the “Thermal protection” section of this

manual for details.

Special Strobe / SOS mode and 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 any of these modes simply release the switch when it is displayed. To

turn off the light (enter into standby mode) fully press and release the switch.

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

display which mode is being used.

Demonstration mode

When entering standby mode simultaneously press and hold the display switch

and the on/off switch to enter into Demonstration mode. In Demonstration

mode, the OLED screen will cycle through the TM26’s various messages.

Simply press any button to exit Demonstration mode.

Lockout Function

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. Simply press the switch and hold for more than

one second to exit lockout mode.

NB:

1. If the display button is pressed when in lockout mode, the OLED

display will show the words “LOCK OUT” as a reminder.

2. When TM26 is kept in a backpack or left unused for extended periods,

Nitecore recommends the bezel is loosened to cut off the power entirely,

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 reach 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 turn off to help conserve power.

Thermal protection

As the TM26 is very compact, extended operation in Turbo mode will

cause the body temperature to continually rise, thus, making it too hot to

comfortably hold. As a result, Nitecore does not recommend using the

TM26 in Turbo mode for extended periods. The TM26 has an integrated

thermal protection circuit which prevents overheating. With the light

turned on in Search/Turbo mode, for user safety and to protect the

flashlight from failure, the TM26 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. Due to the differences in internal

and external air pressure the TM26 may suffer irreparable

water damage.

Changing / Charging Batteries

When the power indicator blinks rapidly it means the batteries need to be

replaced or recharged. Alternatively if the light becomes dim or

unresponsive to adjustment this also indicates batteries need to be

replaced or recharged.

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by a

thin coating of silicon-based lubricant.
