Checklists are provided on the following pages. Note that there is a “Assembly Guide Checklist” and also a “Survival Checklist.” These are redundant. The “Assembly Guide Checklist” is intended as a complete assembly checklist to be used by students in training, or anyone who has not used the rebreather for a period of time and would like a detailed assembly checklist to follow. Some divers will choose to use this list exclusively and print out multiple copies to use as their dive log.
The “Survival Checklist” is intended for users who are thoroughly familiar with assembling and operating the Optima CM and are actively using it. It provides a condensed list of the critical checks that must be performed before every dive. If multiple dives are performed in a single day, this list should be used before every dive.
The “Preflight Checklist” is intended to be performed after gearing up and just before entering the water to begin your dive. It will confirm that all systems are turned on and functioning properly. It is recommended to attach a copy of this checklist to the Optima in a convenient location.
The “Post Dive Checklist” should be used after the dive is over. There are two sections to this list. The first is things that should be done immediately after every dive after getting out of the water, and the second is things that should be performed at the end of your day of diving.
