This is the Chinese-language user manual for the Nitecore EC4 flashlight, built with a unibody lightweight body and a CREE XM-L2 U2 LED that reaches a maximum output of 1000 lumens. The light uses a two-switch interface with five brightness levels and three special modes (strobe, beacon and SOS), plus direct access to ultra-low and turbo from off.
The manual explains turning the light on and off, the standby locator beacon, brightness adjustment, special modes, lockout and unlock, the blue battery level indicator, the built-in advanced temperature regulation (ATR) module, and battery installation in the tail-cap compartment. It lists the EC4's dimensions, weight and ANSI/NEMA FL1 brightness and runtime data, plus cleaning advice and the Nitecore warranty terms. This manual is written in Chinese.

Press the switch button once to turn the light on. Press the switch button once again to turn it off; it then goes into normal standby.
With the light on, press and hold both the switch button and the function button for more than one second to lock it. Press and hold both buttons again for more than one second to unlock.
Each time batteries are installed, or when the function button is pressed while the light is off, the blue indicator in the dual-button switch flashes the remaining charge: three fast flashes mean more than 50%, two mean less than 50%, and one means the battery is nearly depleted.
The built-in advanced temperature control module automatically adjusts brightness output according to the working state and outside temperature to reach the best working condition.
While the light is on, each press of the function button cycles through ultra-low, low, medium, high and turbo. The light remembers the current level and returns to it the next time it is turned on.
