Pre-Dive Checks - Aqua Lung Calypso Owner's Manual

3.2 Pre-Dive Checks

1. Carefully inspect all hoses at their fittings to ensure they are securely
connected into their respective ports on the first stage. Inspect the length of
each hose to ensure that the hoses are not blistered, cut, or otherwise dama-
ged. If hose protectors are present, slide the protectors back to expose the
hose fittings, and inspect the hoses as described above.
2. Visually inspect both the first and second stage regulators for any signs of
external damage.
3. Visually inspect the mouthpiece to ensure that there are no tears or splits.
4. Check that the needle of your submersible pressure gauge is on zero.
5. Check that your VAS or Dual Cam is set to "-". For the Mikron Regulator,
check that your VAK is screwed (see chapter 2.4.3).
6. Fit your regulator to the cylinder (see Chapter 3.1), checking that the hoses
are oriented correctly.
