With the light switched off, press the MODE button to enter red light mode. In this mode, the

secondary red LED will illuminate steadily.

When in red light mode, press and hold the MODE button for more than one second to enter

signal light mode. In this mode, the secondary red LED will flash to serve as a signal light.

Lockout / Unlock

With the light switched on, press and hold the ON/OFF button and the MODE button

simultaneously for over one second to switch the light off and enter lockout mode. In lockout mode,

the EC11 conserves battery power for over 170 days; the two buttons on EC11 will not work, thus

preventing accidental activation of the light. To exit lockout mode, simply press and hold the

ON/OFF button and the MODE button simultaneously for over one second again.

NOTE:

1. When entering lockout mode, the secondary red LED will continuously flash to indicate battery

voltage. Please refer to the “Power Tips” section for more details.

2. When the EC11 is kept in a backpack or left unused for extended periods, Nitecore recommends

the tailcap is loosened or battery is removed to cut off the power entirely, thus preventing

accidental activation of the flashlight or battery leakage.

Power Tips

After battery installation or lockout mode activation, the secondary red LED will flash to indicate

battery voltage (accurate to 0.1V). For example, when battery voltage is at 4.2V, the red LED will

flash 4 times, followed by a one second pause and another 2 flashes. Different voltages represent

the corresponding remaining battery power levels:

Output & Runtime

NOTICE:

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

standards ANSI/NEMA FL1, using 1 x high quality IMR18350 battery (3.7V 700mAh) or 1 x
