If the system is used underwater press purge button lightly or exhale sharply to expel water from the regulator
prior to inhalation.
CAUTION: Failure to purge the HEED regulator before inhaling will result in swallowing water.
4.
Continue to inhale and exhale to a safe and normal rate of ascent. Take small, slow, steady breaths to
maximize the duration of air supply.
NOTE: The HEED utilizes a balanced regulator which means it will provide air in any orientation including the
regulator being upside down or sideways.
CAUTION: If HEED is used until completely empty underwater, it should be referred for five year
service.
