NOTICE

The stated data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1, using two SYSMAX CR123 battery (3V, 1550mAH) under laboratory conditions. The data may vary in real-world use due to different battery usage or environmental conditions.

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. If incorrectly installed, the flashlight will not work.

Switching ON/OFF

To switch ON: Press the “On/OFF” button once to turn the light on. To switch OFF: Press the “On/OFF” button once again to turn the light off.

Note: When EC2 is off, the power indicator (red light) will flash once every 3 seconds to act as a locator. In this mode, the EC2 consumes a very little amount of current (about 0.2mA) to maintain working of the built-in MCU and power indicator. Under such status, two CR123 batteries will last about 1 year in this mode.

Brightness Selection

With the flashlight switched on, each time you press the “MODE” button, it will go through the different preset brightness levels as follows: ultra-low mode→low mode→medium mode→high mode then repeat. Under this mode, the flashlight has a memory function. It can memorize the selected brightness after turning the light off, while next time turning on the light, it automatically resumes to the previously selected mode.

Entering Turbo Mode

With the flashlight switched on, press the “MODE” button for more than 1 Second, EC2 will enter Turbo mode. Press the MODE button again, the flashlight will retreat from turbo brightness and resume to previous brightness. In Turbo mode EC2 circuit will deliver maximum current to make brightness as high as possible.

Note:

1. After 30 minutes working in Turbo mode, the flashlight will automatically restore to the previously selected brightness level to safeguard against overheating.

2. While activating Turbo mode, the brightness level increases about 150 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.

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.

Red Light Mode

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.

Lockout Mode

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 red light indicator also switches off to save energy. Under this mode, the maximum consuming current is about 0.1mA, which ensures two CR123 batteries can maintain its work for around 2 years. In lockout mode, the 2 buttons on EC2 will not work, which can prevent the light from being turned on accidentally. To exit lockout mode, simply press the ON/OFF button for more than 1 second.

Note: When entering lockout mode, the red light indicator light will

continuously flash to advise of battery voltage. Please refer to the “Power Indication” section below.

Power Indication

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

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.

Maintenance

Every 6 months, the threads should be wiped with a clean cloth followed by a thin coating of silicon-based lubricant.
