    Anyone have recommendations on how to remove the switch without breaking it? I know the service manual says to replace it because it breaks if removed.

    I just serviced mine and have a slight leak that I narrowed down to the o ring under the switch.

    Carefully pop the decal, and then you can address the way the switch components clip together (inside & outside halves). If you are really careful, you can save the decal, and bond it back in... or dive without it...

    I have been wanting someone to make a sheet of those decals (thick foil).

    Good luck!

    Got the decal off intact by warming it with a blow dryer and was able to unclip the switch without breaking anything. Now have to reassemble and see what happens.

    Thanks!

    Got it reassembled, hooked it up to a tank and inhalation effort seemed pretty good (just dry not in water yet).

    However, with tank air off, I had a small inhalation leak that seemed to change slightly when the Dive/Predive switch was moved. I had replaced the o ring and it felt like the old parts for the switch snapped together pretty well. I spent some time thinking about this and then it suddenly dawned on me:

    The Dive/Predive switch was leaking from the snap together connection. You have to have the sticker on that switch to make an airtight seal. With the sticker back on with a little Aquaseal, no leak.

    Now to do some diving with it,
