2.8. Electronics

The O2ptima electronics are supplied by Juergensen Marine. Please see the HammerHead

manual for specific user functionality. The O2ptima electronics are shipped out of the

facility with all lock out codes erased from the handset. This renders the electronics

inoperable until the proper code is keyed into each of the handsets. Once the code has been

entered, it will remain unlocked unless the codes are deliberately erased.

Each unit has a specific code therefore the code for one unit will not work on another unit.

In order to receive the code for your O2ptima unit you must complete the following;

• Successfully pass an approved diver level CCR O2ptima course

• All waivers and liability forms have been signed and the originals have been

received by the manufacturer (Asseer & Associates Inc.).

In order to receive training on your unit the lock out code will be sent to the instructor of

your choice. Upon successful completion of the course the instructor will hand over the

lock out code for your unit.

The O2ptima electronics also have a Trimix capability. The Trimix functionality is also

locked out by a secondary lock out code. In order to unlock the Trimix functionality you

must successfully complete an approved Trimix diver level CCR course. The unit can be

“re-locked” at any time by clearing the codes.

Each handset is powered by a stand alone battery. The recommended battery for the

O2Ptima is the Saft LS14500. The (+) plus side of the battery should be at the bottom of

the battery compartment while the (-) negative side of the battery should be against the

spring. Tighten the battery cap using a coin.

The O2ptima electronics have also been programmed to remain on the start-up screen if the

power is ever reset at the surface or during a dive. This will only happen on the primary if

the battery no longer has enough power to fire the solenoid valve and if the is not enough

power in the secondary to provide alarms.

WARNING!!! IF THE START SCREEN APPEARS ON EITHER OF YOUR

HANDSETS DURING A DIVE, ALL TISSUE INFORMATION HAS BEEN RESET.

DO NOT USE THIS HANDSET FOR DECOMPRESSION INFORMATION.

2.9. First Stage Regulators

The O2ptima has two first stage regulators, one for diluent and one for oxygen. The IP

(intermediate pressure) for the diluent regulator is to be set to factory standards (135 psi).

The oxygen first stage IP must

be set to 110 psi in order for the solenoid valve to function

properly. This should be verified during unit assembly and corrected immediately if any

discrepancy is noted.
