Alpha 2000 suitable for all types of diving. It has a narrow beam angle. It has very compact head light.

   

 

 

 

 

Operation principle of the indicator of the battery discharge

 

   
   

 

- all the three LEDs are constantly on, changing its color, as far as battery discharges, from green to yellow, from yellow to red.

- when all of LEDs turn red, the battery should be charged. Failure to do this will result in automatic switching to the power saving mode, 2 red LEDs will be blinking at that.

- if you still haven’t charge the battery after that, the light switches to the emergency mode with severe power saving. Only one red LED will be blinking at that and the light intensity will fade out:

 

To charge the battery you do not need to open the canister. Charging is made via the wet contacts. That excludes the possibility of leakage.
