NITECORE TM28 Tiny Monster Flashlight Instruction Manual

warning icon...WARNING:

It is of crucial importance to ensure IMR batteries are installed correctly as labelled. Installing these batteries backward poses significant risk of short-circuiting, which in turn leads to combustion or explosion.

Battery installation

NITECORE TM28 Tiny Monster Flashlight - 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 iconWARNING:

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

NITECORE TM28 Tiny Monster Flashlight - Battery inmstraction

NOTE: The stated data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1, using 4 x IMR18650 batteries (3.7V, 3100mAh) under laboratory conditions. The data may vary in real-world use due to different battery use or environmental conditions.

* The runtime for Turbo and High mode are the testing result before starting temperature regulation.

NITECORE TM28 Tiny Monster Flashlight - The runtime for Turbo and High mode are the testing result before starting temperature regulation

NOTE: The stated data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1, using 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.

* The runtime for Turbo and High mode are the testing result before starting temperature regulation.

* The use of the 6000 lumens Turbo: All 18650 batteries must be capable for a discharge current of at least 8A each, or use the product with the NITECORE NBP68HD battery pack. It is recommended to use the product with NITECORE protected IMR 18650 3100mAh (For TM28).

Operating instructions

Note: This product uses a two-stage power switch, access to its various functions depends on the extent the switch is pressed.

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.

Caution iconCaution: 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 iconSolution: Reinstall batteries and select the correct battery type when prompted. To guarantee the best user experience, it is recommended to use NITECORE IMR18650 batteries.

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.

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 TM28’s various messages. Simply press any button to exit Demonstration mode.

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.

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:

  1. When the product is turned off, press the display switch and battery voltage information will be shown for 10 seconds.
  2. 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.

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.
