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 consistently when

power levels are low.

3. Each time batteries are inserted or the light is put into lockout mode,

the power indicator light will blink in various patterns to indicate the

battery voltage (accurate to ±0.1V). For example, when the 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 two

more blinks, indicating a total battery voltage of 4.2V.

Changing / Charging Batteries

When the power indicator blinks rapidly it means the batteries need to be

replaced or recharged. Alternatively if the light becomes dim or

unresponsive to adjustment this also indicates batteries need to be

replaced or recharged.

Maintenance

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

a thin coating of silicon-based lubricant.

Tips

Inserting batteries in a dark environment: Two of the four battery slots in

the EA8’s battery compartment feature grooves indicating that batteries

should be inserted with the negative (-) ends facing forward, while the two

slots with no grooves require the batteries to be inserted with the positive

(+) ends facing forward. In this way, batteries can be inserted correctly

through tactile feedback alone.

After loading the batteries, the power indicator light will blink to indicate

the battery voltage. Please refer to the “Power Tips” section of this

manual for details.

WARNING

1. Insert batteries using the image on the inside of the battery

compartment as a reference.

2. Do not mix rechargeable and non-rechargeable batteries.

3. Do not mix batteries of different types/brands.

General Operation

The EA8 utilizes a 2-stage switch similar to a camera shutter button. The

light’s numerous functions are selected according to the depth the switch

is pressed. The EA8 has two modes: Daily mode and Search / Turbo

mode.

Operating In Daily Mode

1. With the light turned off, press the switch partway down and release

within a second to enter daily mode.

2. Daily mode contains four brightness levels: ultra-low, low, medium, and

high. Pressing the switch partway down in quick succession will cycle

through these modes. Pressing the switch partway down and holding

for more than one second when in daily mode will enter into turbo

mode. See Turbo / Search mode instructions below.

3. The light is turned off (put into standby mode) by pressing the button

all the way down and releasing within a second. This will also

memorize the last daily mode used.

4. Daily mode has a momentary function which allows the light to be

turned on only when the switch is held. With the light turned off, press

the switch partway down and hold to activate daily mode’s momentary

function. The light will turn off the moment the switch is released.

Operating in Search / Turbo Mode

1. With the light turned off, press the switch all the way down and release

within one second to enter turbo mode. To cycle between high and

turbo modes press the button partway down while in turbo mode.

2. To turn the light off when in turbo mode, once again press the button all

the way down and release within one second.

3. With the EA8 turned on in Search/Turbo mode, partway presses of the

button will cycle between high and ultra-high mode. There is no

memory function in Search/Turbo mode.

Standby Mode / Lockout and Unlock functions

With the light turned on, press the switch all the way down and release

within one second to enter into standby mode. In this mode, the light will

consume small amounts of power to maintain the settings in the MCU

(micro control unit) but appear to be turned off. When in standby mode

the power indicator light will flash once every three seconds to show the

location of the light.

With the light turned on, press the switch all the way down and hold for

more than one second. The light will turn off and enter into lockout mode.

Lockout mode consumes almost no battery power and prevents the light

from accidentally turning on. Holding the switch for more than one second

to exit the lockout mode.

NB:

1. When entering lockout mode, the power indicator will flash to indicate

specific battery voltage. Please refer to the “Power Tips” section of this

manual for details.

2. When EA8 is kept in a backpack or left unused for extended periods,

Nitecore recommends the bezel is loosened to cut off the power entirely,

thus saving battery power and preventing accidental activation of the

flashlight.

Special Strobe / SOS mode and

Location Beacon

With the light turned on, press the switch all the down twice in quick

succession 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 select any of these modes

simply release the switch when it is displayed. To turn off the light fully

press and release the switch.
