Bettery options

WARNING：Must not be used with CR123/RCR123 batteries.

*Nitecore 18650 are recommended to ensure complete compatibility.

Output & Runtime

NOTE:The stated data has been measured in accordance with the international flashlight

testing standards ANSI/NEMA FL1, using 4x IMR18650 batteries (3.6V, 3100mAh) or 4 x

Li-ion 18650 batteries (3.7V, 3400mAh) under laboratory conditions. The data may vary in

real-world use due to different battery use or environmental conditions.

* Runtimes for turbo and high are calculated based on theoretical arithmetic.

* To use the 6000 lumens output, all 18650 batteries must be rechargeable and have at

least 8A discharge current each or use with NITECORE NBP68HD battery pack.

Battery installation

Insert four 18650 Li-ion or four 18650 IMR batteries with the positive terminal pointing towards

the correct direction, as illustrated in the diagram below. When using flat top 18650 batteries,

ensure the flat top battery connector is placed on the positive terminal of the batteries.

WARNING：

1. Insert batteries with polarity pointing towards the right direction as labelled on inside of the

battery compartment, incorrectly inserted batteries will render the product inoperative and

poses risk of short-circuiting.

2. When using flat top IMR batteries, ensure the flat top battery connector is placed on top of

the positive terminal.

3. It is not recommended to use the product with less than 4 x 18650 batteries, this may cause

the product to function improperly and shorten battery life span.

User Manual

Thanks for purchasing NITECORE!

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

Battery selection

Upon each battery installation, a battery selection prompt comes up on the OLED display,

select the correct battery type by pressing the display switch and press the power switch to

confirm:

1. Li-ion. Regular rechargeable li-ion batteries allowing for max output of 4500 lumens.

2. IMR. High discharge li-ion batteries allowing for max output of 6000 lumens.

3. Batt Pack. NBP68HD, optional battery pack allowing for max output of 6000 lumens.

If no action is taken for 10 seconds after battery installation, the OLED display will enter

standby mode.

Operating instructions

Note: This product uses a two-stage power switch, access to its various functions depends on

the extent the switch is pressed.

ON/OFF

With the light turned off, pressing the power switch partway or all the way down will turn the

light on, press the switch all the way down again to turn the light off.

Modes

The TM28 comes with 2 modes:

-Daily mode: This mode has 4 brightness levels, press the switch partway down to turn the

light on in daily mode, pressing the switch partway down repeatedly cycles

the brightness through Ultralow-Low-Mid-High, this mode has memory

feature.

-Search mode: This mode has 2 brightness levels, press the power switch all the way

down to turn the light on in search mode, pressing the switch partway

down cycles brightness through High-Turbo. Alternatively, hold the switch

all the way down to turn the light on at “Turbo”, releasing the switch turns

the light off.

Special functions

With the light turned on, press the switch twice in quick succession to enter strobe, press the

switch partway down repeatedly to cycle through Strobe-SOS-Beacon, press the switch all the

way down to turn the light off.

OLED display

This product has an onboard OLED display that provides real-time operating data:

1. When the light is turned on at level 1-5, a series of data sets will be shown in the order of

brightness level-battery voltage-battery level-remaining runtime-operating

temperature-standby, with a 1.8 second delay before the next data set comes up on display.

2. When using any of the special functions, the name of the function will be displayed.

Lockout

With the light turned on, hold down the switch for 1 second to enter lockout mode, this is

designed to prevent accidental activation. To unlock, hold down the switch for 1 second again.

Batteries are expected to last for 12 months in lockout mode.

Caution: Correct battery type must be selected upon battery installation, setting

battery type to IMR while using regular 18650 li-ion batteries may render the

product inoperative when switching to turbo (when OLED shows 6000 lumens).

Solution: Reinstall batteries and select the correct battery type when prompted.

To guarantee the best user experience, it is recommended to use NITECORE

IMR18650 batteries.

Note: When the product is expected to be left unattended for extensive period, it is advised to

loosen the tail cap.

Power tips

When the product is turned on, the built-in power indicator under the switch will blink to

indicate remaining battery:

1. When batteries are full, the indicator will stay lit.

2. When batteries reach 50%, the indicator will blink once every 2 seconds.

3 When batteries reach 10%, the indicator will blink rapidly.

Note: When the product is turned off, press the display switch and battery voltage information

will be shown for 10 seconds.

Recharge

To initiate the charging process, connect the charging port to a power outlet with the adaptor

provided:

1. Charging in progress: “charging…” will come up on the OLED display, the power

indicator will blink once every half a second.

2. Charging anomaly (damaged batteries/no batteries presented): “Error” will come up

on the OLED display, the power indicator will blink rapidly. This usually indicates no battery,

incompatible or damaged batteries, or flat-top batteries are installed without the battery

connector.

3. Charging complete: “Chg.Finished” will come up on the OLED display, the power

indicator will stay lit.

4. Charging duration: Fully charging four 18650 batteries takes approximately 7 hours.

Temperature regulation

Heat generated by the LEDs can be substantial, prolonged operation at “Turbo” level will

significantly increase operating temperature. Therefore, it is not recommended to use “Turbo”

for long period of time. The TM28 has temperature regulation, when operating temperature

reaches 60° Celsius (max bearable temperature by human skin), the TM28 automatically

lowers its output to prevent temperature from increasing.

Note: Do not submerge the product in water or any liquid when it has generated sufficient

heat, doing so will cause pressure inequalities and significantly increase risk of water

damages.

Cautions

◆ Avoid direct eye exposure, it may impair vision permanently.

◆ Do not disassemble, modify this product, doing so may damage the product and void the

warranty.

◆ Use quality protected batteries only. If the product will be left unattended for extensive

period, remove batteries to avoid leakage and explosion caused by inferior batteries.

◆ This product incorporates voltage sensitive protection feature, when voltage drops below a

certain threshold, output will gradually decrease to the lowest level; When voltage drops

below 3V, the product will shut down to protect batteries.

◆ Replace the O-ring immediately when it is found damaged.

◆ Every 6 months, threads should be wiped with a clean cloth followed by a thin coating of

silicon-based lubricant.
