i got 10 of the m401 manual batteries and the air flow is horrendous, i get pretty much no air flow at all, and i tried a few of them, but my auto back on and everything was fine. Am i doing something wrong ? I was really excited to get these as I work in a loud bar environment and the auto would be on without me knowing. Very dissappointed at the moment, any tips or suggestions would be appreciated.
Hi cazzz, -
where your atty screws onto the batt- there are 4 channels on the atty-
thats where the air is drawn in-
on mine, -
there are no blockages, -
how does yours look ??
there is also a hole on the shoulder of the battery
directly below the neck containing the screw threads,-
which also assists airflow, the auto batts have this also,-
check this one for blockage also --
mine are all clear and my draw is a nice medium, better than the auto --
because I don't have to suck hard to activate a manual switch-
