LA series passed Water proof IPX5 test

We did reliability test for LA series under the level of Water proof IPX5 and all passed without any playback problem.


Tested product : LA-12/LA-12H


We believe that LA series (except BT series) have an enough ability for passing IPX6 level because of its 

inside reliable construction.

We can assume that LA-1 and LA-14 series(except BT series)as they are same assemble technology and parts. Do not worry about it!
