User manual NITECORE EC2

[. . . ] Replace the tail cap and fasten tightly Dimensions Length: 99mm Head Diameter: 25. 4mm Tail Diameter: 24mm Weight: 59g (without battery) Accessories Quality holster, lanyard, spare O-ring Battery Options SIZE Primary Lithium battery 18650 Rechargeable Li-ion battery Rechargeable Li-ion battery Nominal voltage Compatible Y (Recommended) Y (Recommended) Y Note: EC2 is compatible with two primary CR123 Lithium batteries and one 18650 rechargeable Li-ion battery. When installing battery, EC2’s built-in MCU will automatically detect the installed battery type, and then automatically select the best suited driving data and battery capacity detecting data. WARNING Always ensure batteries are inserted with the positive (+) ends pointing toward the flashlight head. [. . . ] After 30 minutes working in Turbo mode, the flashlight will automatically restore to the previously selected brightness level to safeguard against overheating. While activating Turbo mode, the brightness level increases about 100 lumens. Due to adaptability of human eyes, this brightness increase may not be apparent within close range observation. In real-world usage, Turbo mode can help EC2 throw to a longer range. Power Indication Entering Strobe and SOS Mode With the light switched off, press the “ON/OFF” button for more than 1 second to enter Strobe mode. In strobe mode, press any button (ON/OFF or MODE) to exit strobe and switch the light off. With the light switched off, press the “MODE” button for more than 1 second to enter SOS mode. In SOS mode, press any button (ON/OFF or MODE) to switch off the light and quit SOS mode. With the light switched on, and when the battery power has been consumed by about 50%, the power indicator light (on the control panel) will flash once every 6 seconds as a reminder of battery capacity. When the battery power is almost depleted, the power indicator light will flash 3 times every 3 seconds to indicate low battery capacity. When entering lockout mode, the power indicator will automatically detect and notify you of battery voltage (accurate to ±0. 1V) with a series of flashes. For example, if the battery voltage is 4. 2V, the indicator will flash 4 times, followed by a one second pause and then another 2 flashes. Battery replacement Red Light Mode If battery level is low, the red power indicator light will flash three times every 3 seconds. If the power level is critically low, the light will become very dim and unresponsive to brightness adjustment. A replacement battery is required at this time. With the light switched off, press the “MODE” button to enter red light mode. In this mode, the power indicator will continuously emit red light (0. 2 lumens). Press the “MODE” button once again to quit the red light mode. Maintenance Every 6 months, the threads should be wiped with a clean cloth followed by a thin coating of silicon-based lubricant. Lockout Mode Warranty Service With the light switched on, press the ON/OFF button for over 1 second to enter lockout mode. In lockout mode, EC2 power source system will shut down most of the circuit components to reduce its power consumption. The MCU only consumes small amount of power to maintain its work. [. . . ] The warranty is nullified in all of the following situations: 1. The product(s) is/are broken down, reconstructed and/or modified by unauthorized parties. The product(s) is/are damaged through improper use. [. . . ]
