Finally ensure equalization is achievable.
Doffing
To remove the mask (Figure 16), grasp the
bottom of the mask with both hands and
use thumbs to grasp bottom buckle tabs
and loosen. Then, pull the mask out and off
of the head.
DIVING THE SPECTRUM FULL-
FACE MASK
Pre-Dive
Prior to entering the water, check the
submersible pressure gauge (SPG). This is done by taking two deep
breaths through the mask while observing your SPG. There should be a
slight
drop in pressure. If there is a significant drop in pressure, check that
the air supply is working properly. If the gauge shows a drop, and the air
supply is turned on correctly, have the equipment examined immediately
for proper function.
Post-Dive Procedures
After a diver has completed diving, remove the Spectrum FFM. Thoroughly
rinse the Spectrum FFM in clear, fresh water and pat it dry with a lint-free
absorbent cloth. If necessary, a mild detergent may be used for cleaning the
Spectrum FFM.
Never
use any harsh detergents, abrasives, or solvents
on your Spectrum FFM. Use caution when drying the visor after diving in
a sandy environment to prevent any scratching of the lens.
Do not use
paper towels to dry or clean visor—scratching of the lens may occur.
Hang the Spectrum FFM upside down to allow for any trapped water
to drain to the top of the skirt. Wipe out the excess water and allow the
Spectrum FFM to air dry prior to storing. If stowing a damp mask, remove it
from the bag as soon as possible and allow it to dry completely to prevent
any mold and mildew from forming.
Rinse the Spectrum FFM and regulator with fresh water. Shake any
remaining water from the Spectrum FFM.
