Problem with my DS-125

After a shallow dive with on a sandy bottom, I noticed to hear creakiness, screech noises every time that I switch position and rotate my Ikelite's ONOFFTEST switch. It look's like I have sand grains stucked under my switch.

I tried to dip the strobe in fresh water and rotate the switch to remove the sand grains with no results.

Is it safe to open the switch's screw and remove the grains?

Any suggestions?

I would think that it would be OK to remove the switch dial...the shaft is sealed...but I would contact Ikelite by e-mail to make sure
