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.

Simply press any button to exit the red light /signal light mode.

Special modes (Strobe/Location/SOS)

With the light switched on, press and hold the MODE button for more than one second to enter

strobe mode. When in strobe mode, press and hold the MODE button for more than one second

again to cycle through Location Beacon, SOS and Strobe modes. To exit, simply press the MODE

button to resume the brightness level last used, or press the ON/OFF button to switch the

light off.

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 EA21 conserves battery power for over 300 days; the two buttons on EA21 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. Upon entering lockout mode, the secondary red LED will flash to indicate battery voltage. Please

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

2. When the EA21 is kept in a backpack or left unused for extended periods, Nitecore recommends

the tailcap is loosened or batteries are 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 2.4V, the red LED will

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

the corresponding remaining battery power levels:
