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. [. . . ] 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. to develop the ANSI FL1 standard of measurement. Product testing data is in accordance with these internationally recognized scientific standards. Thanks for purchasing NITECORE! ® ALL-ROUND Flashlight Expert 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. Power Tips 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. To turn the light off when in turbo mode, once again press the button all the way down and release within one second. With the EA4 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. NB: For user safety and to prevent overheating / failure, the EA4 will automatically switch to high mode after three minutes of use in Turbo mode. 1. When the light is on, the power indicator will blink once every two seconds when power levels reach 50%. When the light is on, the power indicator will blink consistently when power levels are low. 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. 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.
