 before diving, perform a routine check of the demand regulator,

 listen to all the demand regulator's connections for possible air outflow,

 check if the air feeding the regulator has an unpleasant smell,

 push the diving regulator's inflate button and check for air outflow that stops

after releasing the inflate button,

 insert the diving regulator's mouthpiece to your mouth and take a few quick

breaths, looking at the pressure gauge or other monitoring device. The

monitoring device's indications should not change,

 test for water tightness, before submerging, insert the diving regulator's

mouthpiece to your mouth, clench your teeth and then seal the connection

between your oral cavity and a mouthpiece with your mouth.

8. The use during diving

 if the second-stage pressure reduction is equipped with Venturi effect's

adjustment system, the adjusting knob must be set in the position MAX, DIVE

or + during diving,

 during diving, breathe steadily and avoid quick and shallow breathing,

 the demand regulator's design allows good visibility even when air bubbles

flow out from the diving regulator during exhalation. Except for the situation

when, being underwater, a diver looks at the surface and exhales at the same

time,

 whenever you take the diving regulator out of your mouth and then reinsert it,

first exhale or push the diving regulator's inflate button. Otherwise, you can

choke on water.

9. The use after diving, maintenance and storage

Once diving is finished, you must:

 take the diving regulator out of your mouth,

 remove remaining water from the diving regulator and clear it by pushing the

inflate button,

 close the shut-off valve (valves) of the cylinder/twinset,

 using the inflate button, adjust pressure in the demand regulator to the

ambient pressure,

 unscrew the pressure reducing valve from the cylinder/twinset,

 wash out the demand regulator in clean, fresh water, while clogging the

pressure reducing valve's mounting ferrule's inlet. Please ensure that all HP

and LP ports are plugged or connected properly. These steps are particularly

important after diving in salt or chlorinated water. When rinsing do not push

the constant flow button on the diving regulator. It will prevent ingress of water

to the interstage hose or the pressure reducing valve,

 when rinsing the diving regulator, check if the breathing resistance adjustment

knob is in a close position,
