Start Up Diagnostics
Problems are most frequently found during start up. Your pre-dive check should catch these problems. Your post dive check will provide a baseline for the next dive and may catch problems that can be solved before the system is needed urgently.
If the system does not start or respond correctly, eliminate the tether from the set up and test again.
