SF2 ECCR OPERATION MANUAL
Safety
Important Safety Instruction
This rebreather is intended for use by certified scuba divers who have completed a
rebreather course, or those who are being trained and supervised by a qualified
instructor.
WARNING
Follow all instructions and adhere to these safety measures.
Incorrect or improper handling of the rebreather can result
in serious injury or death.
WARNING
This manual is NOT a substitute for a rebreather training course
administrated by a qualified instructor. DO NOT USE a
rebreather until you have practiced and perfected practical skills,
including emergency skills, in a supervised environment and
under the supervision of an instructor who is certified by a
nationally recognized diving training organization and authorized
to train in SF2 rebreather use.
WARNING
Careless use of the SF2 can cause unconsciousness due to lack
of oxygen in any environment without prior warning signs.
Careless use of the SF2 at depths underwater greater than 6
MSW (meters of sea water) [20 FSW (feet of sea water)] can
cause unconsciousness without warning. Either of these
situations can cause serious injury or death. The SF2 is equipped
with a sophisticated electronic control system that enables a
properly trained user to avoid these situations. It is the sole
responsibility of the user to carefully monitor the displays on this
system while using the SF2 and to have a knowledge of response
measures in the event of a problem.
