Sherwood Scuba Insight Manual Manual page 3

The following symbols are used throughout this manual to bring your attention to situations that require
special consideration. Be sure to read and follow all instructions carefully.
N
Throughout this owner's manual reference is made to the term 'breathing gas'. The rationale being that the INSIGHT can be
used for Air dives or Nitrox dives. For clarity, these terms are defined as -
Breathing Gas - the gaseous mixture breathed during a dive.
Air - a breathing gas that contains approximately 21% oxygen and 79% nitrogen (nature's common nitrogen-oxygen mixture).
Nitrox - a nitrogen-oxygen breathing gas that contains a higher fraction of oxygen (22 to 50%) than air.
A WARNING is used before a procedure that will result in serious injury or death if the
procedure is not followed carefully.
A CAUTION is used before a maintenance technique that will result in damage to parts if
that technique is not followed carefully.
A NOTE is used to emphasize an important maintenance technique.
