Intelligent Memory Circuit

1. Turn on/off by toggle switch: mode A will be activated on Low each time it is turned on, mode B and C will automatically memorize the last selected output. 
2. Turn on/off by electronic switch: the light memorizes the last selected output. When turned on again the previously used output will be recalled.
   Note: mode D will be activated on Turbo each time it is turned on.

Intelligent Brightness Downshifting Sensor

The flashlight has a built-in intelligent sensing circuit. When the light surface is close to the lighting object (about 60mm) for more than 1.5 s, the flashlight will automatically downshift the output level to Low output of mode A to avoid danger caused by high temperature. When the light surface is more than 0.8 s away from the lighting object, the flashlight automatically recalls the previously used output level.

Turning on/off Intelligent Brightness Downshifting Sensor

*By default the sensor is On

To turn Off: With the light locked, press and hold the electronic switch for over 10 seconds. The light will flash quickly 8 times to indicate the sensor has been disabled.  

To turn On: With the light locked, press and hold the electronic switch for over 10 seconds. The light will flash 2 times to indicate the sensor has been enabled.

Charging

1. First switch off the light and open the anti-dust cap, plug the USB Type-C socket of the charging cable into the light, then connect the other end of the charging cable into the included adapter.
2. When charging, the charging indicators will flash from left to right to display charging status. The five indicators will be constant-on after charging is complete.
3. Be sure to close the anti-dust cover once charging is completed.

Power Bank Function

1. Switch off the light and open the anti-dust cap and insert the USB Type-A socket of the charging cable into the USB discharging port of flashlight, then connect the other USB Type-C socket of the charging cable to the digital device with an USB Type-C port. 
2. Single click the electronic switch to begin discharging, the indicators will recede from right to left to display the status.
3. Be sure to close the anti-dust cover once charging is completed.

Note：

1. The light can only be turned on at 100 lumens when charging.
2. The light and the included charging cable support QC2.0, PD2.0 fast charging protocols.The normal charging time is approximately 4 hours from depletion to full charging.
3. All modes are available when discharging.
4. If the voltage is too low, the light will stop discharging.

Battery Level Indication

With the light switched on/off(including locked status), single click the electronic switch to check the battery level and indicators will last for 3 s. Single click the electronic switch again in 3 s to close the indicators. 

• Five blue lights on：100%-80%
• Four blue lights on：80%-60%
• Three blue lights on：60%-40%
• Two blue lights on：40%-20%
• One blue light on：20% - 1%

Intelligent Overheat Protection

The flashlight will accumulate a lot of heat when used on High mode for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user the reselection of High mode. 

Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, one battery level indicator blinks to remind you to timely recharge the battery until it is completely power off.

Usage and Maintenance

• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Rotate the toggle switch in anticlockwise direction to lock the flashlight to avoid accidental activation.
• Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
• Periodic cleaning of the battery contacts improves the lamp's performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons:
  A: Poor battery level.
  Solution: Recharge the battery.
  B: The product, battery contact or other contacts are dirty.
  Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please contact your authorized distributor.

Warning

• Do NOT place this light in the reach of children!
• Do NOT shine the light directly into the eyes of anyone!
• Do NOT shine flammable objects at close range, to avoid burning objects or causing danger due to high temperature!
• Do NOT use the light in inappropriate ways such as biting in the mouth, to avoid personal injury or life threats if the light or internal battery fails!
• This light will accumulate a lot of heat while working, resulting in a high temperature of the flashlight shell. Pay attention to safe use to avoid scalding.
• Turn off and lock the light to prevent accidental activation when the light is placed in a closed and flammable environment such as pockets and backpacks!
• The LED of this flashlight is not replaceable; so the whole light should be replaced when the LED reaches the end of its life.
