Safety considerations

I UWATEC Aladin PRIME

• Avoid repeated heavy workload while at depth.

• Plan the dives to be shorter if they are made in cold water.

• After finishing the decompression or at the end of a no-stop dive, the final stage of the ascent should

be as slow as possible.

• You MUST be familiar with all signs and symptoms of decompression sickness before using Aladin

PRIME! Seek IMMEDIATE treatment for decompression sickness should any of these signs or symp-

toms occur after a dive! There is a direct correlation between the effectiveness of treatment and the

delay between the onset of symptoms and the treatment for decompression sickness.

• Only dive with Nitrox after you have been thoroughly instructed by a recognised institution.

Repetitive dives

• Do not start your next dive before your CNS O

% status has dropped below 40%.

• When diving with Nitrox, make sure your surface interval is long enough (just like diving with com-

pressed air). Plan for a minimum surface interval of two hours. Oxygen, too, needs sufficient time to

leave the body.

• Match gas mixture to the intended dive.

• Do not attempt a repetitive dive if the no-dive warning

is visible on the display.

• Plan a day without diving once a week.

• If you have to change computers, wait at least 48 hours before carrying out your next dive.

• Diving after a reset of the remaining saturation (reset, see page 32, or battery replacement, see

page 35) may lead you into

potentially

hazardous situations which could result in death or serious

injury. After a reset of the remaining saturation do not dive for at least 48 hours.

Altitude and diving

• Do not dive at altitudes higher than 4000m (13000ft).

• After a dive do not rise to altitudes that Aladin PRIME prohibits via the flashing altitude

range number (see page 27).

Flying after diving

• After diving, wait at least 24 hours prior to flying.
