NOTICE

The above data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1 using one x 3.7V 650mAh Nitecore RCR123 battery, one x 3V 1550mAh Nitecore CR123 battery and one x 1.2V 2500mAh AA battery under laboratory conditions. The data may vary slightly during real-world use due to battery type, individual usage habits and environmental factors.

Infinite brightness adjustment varies from 0.1 to 550 lumens and is manually adjusted by rotation of the Smart Selector Ring. Subsequently, runtimes will vary anywhere from 45 minutes to 150 hours depending on chosen level of output.

NITECORE (SYSMAX) is a member of PLATO, participating in and helping to develop the ANSI/NEMA FL1 standard of measurement. Product testing data is in accordance with these internationally recognized scientific standards.

Battery Installation

Insert one (R)CR123 battery with the positive pole pointing forward (toward the light head).

NOTE:

1. Ensure batteries are inserted with the positive (+) end pointing to the head. The SRT3 will not operate with incorrectly inserted batteries.

2. Please do NOT light directly to the eyes, which will hurt the eyes.

Switching ON/OFF

To switch ON: Press the button on the tailcap until a “click” is heard. To switch OFF: Press the button on the tailcap a second time until a “click” is heard.

Momentary Illumination

Momentary illumination can be achieved by switching the flashlight off and then half pressing and holding the tail switch. Release switch to turn the light off.

Adjusting Output

With the light turned on, slowly rotate the Smart Selector Ring (adjacent to the bezel) in a counter-clockwise direction to cycle through the following brightness levels: beacon -> SOS -> police warning signal -> blue mode -> red mode -> lower mode -> infinite brightness modes -> turbo mode -> strobe mode. These modes may be cycled through in reverse by rotating the Smart Selector Ring in a clockwise direction.

Note: When using the SRT3 in infinite brightness mode, runtime will increase when lower levels of output are selected.

NB:

For user safety and to prevent overheating / failure, the SRT3 will automatically switch to high mode after three minutes of use in Turbo mode. Slowly rotate the Smart Selector Ring or press the tail switch again to reactivate turbo mode when needed.

Maintenance

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

Using AA extension tube

The SRT3 can utilize one AA extension tube. Please follow the diagram to assemble the body, and you can use one AA battery to power the light.
