NOTICE

Stated data has been measured according to the international flashlight testing
standards ANSI/NEMA FL1 using a quality Nitecore 18650 (3.7V 2600mAh) battery or
two Nitecore CR123 (3V 1700mAh) batteries under laboratory conditions. The data may
vary due to individual usage habits and environmental conditions.

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

Battery installation

Insert one 18650 battery or two CR123
batteries with the positive poles pointing
forward (toward the head).

Note: After loading the batteries, the
power indicator light will blink to indicate
battery voltage. Please refer to the “Power
Tips” section of this manual for details.

EC20

WARNING

1. Ensure batteries are inserted with the positive (+) end pointing to the head. The
EC20 will not operate with incorrectly inserted batteries.

2. When the EC20 is kept in a backpack or left unused for extended periods of time,
Nitecore recommends all batteries are removed to prevent accidental activation of the
flashlight or battery leakage.

User Manual

ON/OFF

Press the button until a click is heard to switch the light on
Press the button once again until a click is heard to switch the light off

Brightness Levels

With the EC20 switched on, press and hold the button for more than 0.5 second to
cycle through brightness levels of ultra-low, low, medium and turbo. To select a
desired brightness level, simply release the button when that level is being displayed.
This mode provides an intelligent memory function to ensure direct access to the
previously used brightness level when the EC20 is reactivated.
Note: when in turbo mode, the EC20 will reduce output luminance automatically after
5 minutes of use to prevent overheating and extend battery longevity

Instant Ultra Low

With the EC20 switched off, press and hold the button for more than one second to
access an ultra-low output mode of 1 lumen.

Special Strobe / SOS mode and Location Beacon

Press the button twice in quick succession in any state to enter Strobe mode. When
in strobe mode, press the switch all the way down and hold for more than one second
to cycle through Strobe, SOS and Location Beacon modes. To exit any of these
special modes, simply press the button again. The EC20 does not have a memory
function for special modes.

Power Tips

1. When the light is on, the power indicator will blink once every two seconds when
power levels reach 50%.

2. When the light is on, the power indicator will blink quickly when power levels are
low.

3. Each time batteries are inserted, the power indicator light will blink in varying
patterns to indicate battery voltage (accurate to ±0.1V). For example, when battery
voltage is at a maximum charge of 4.2V, the power indicator will blink 4 times in quick
succession, followed by a one second pause, and then two more blinks, thus
indicating the battery voltage detected is 4.2V.Different voltages represent the
corresponding remaining battery power levels :

Replacing Batteries

blinks rapidly, output appears to be dim or the flashlight becomes unresponsive.

Maintenance

of silicon-based lubricant.
