Brightness Levels

With the light turned on, press the mode switch repeatedly to cycle through brightness levels of

ultralow, low, medium, high and turbo. This mode has memory effect that ensures direct access to

the brightness level last used.

Direct Access to Ultralow/Turbo

With the light turned off, press and hold the on/off switch for over one second to enter ultralow

level (1 lumen).

With the light turned off, press and hold the mode switch for over one second to enter turbo

level (1000 lumens).

Special Modes (Strobe/Location Beacon/SOS)

With the light turned on, press and hold the mode switch for over one second to enter strobe

mode. To cycle through location beacon/SOS/strobe modes, press and hold the mode switch for

over one second again. To exit, press the on/off switch to turn the light off.

Strobe Ready

With the light turned off, press the mode switch twice in quick succession to enter strobe mode

directly. To exit, simply press any switch to turn the light off.

Lockout/Unlock

With the light turned on, press and hold both switches for over one second to turn the light off and

enter lockout mode. In this mode, the two switches will not have their respective functions, thus

preventing accidental activation. To unlock, press and hold both switches for over one second

again.

NOTE:

1. When in lockout mode, the EC4GT will remain operational using 2x18650 batteries for over 12

months.

2. When the EC4GT is kept in a backpack or left unused for extended periods, Nitecore

recommends batteries are removed to cut off power entirely and thus prevent battery leakage or

accidental activation.

Power Tips

After battery installation or with the mode switch being pressed when the light is off, the blue

power indicator built into the switch will blink to indicate remaining battery power. The power

indicator will blink three times when power levels are above 50%; twice when power levels are

below 50%; and once when battery is close to depletion.

ATR Technology

Advanced temperature regulation (ATR) technology allows the EC4GT to dynamically adjust output

performance according to its internal temperature. This prevents damage from overheating and

prolongs its working life.

Changing / Charging Battery

Batteries should be replaced or recharged when output appears to be dim or the flashlight

becomes unresponsive.

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by a thin coating of

silicon-based lubricant.
