DONNING
5. Push headband pad towards neck, retighten the
straps (if necessary) for best visibility and fit. Tuck in
the ends of the straps so they flat across the head.
FACEPIECE FIT CHECK
Check the inhalation valve, inhale. If you do not
receive sufficient flow of air, do not use facepiece. The
facepiece must be repaired or replaced. Failure to fol-
low this precaution can result in serious personal
injury or death.
1. To check for facepiece
fit, hold the palm of
your hand over the inlet
connection and inhale.
Hold your breath at
least 10 seconds. The
facepiece should col-
lapse and stay col-
lapsed against your
face. If it does not,
readjust the facepiece
and test again. If this
does not correct the leak, do not use the facepiece.
2. Test the exhalation
valve, take a deep
breath and hold it.
Block the inlet connec-
tion with the palm of
your hand and exhale.
If the exhalation valve
is stuck, you may feel a
heavy rush of air
around the facepiece.
Note:
You may need to exhale sharply to open the valve.
If this does not release the valve, do not use the face-
piece.
This device may not seal properly with your face if you
have a beard, gross sideburns, or similar physical
characteristics (see NFPA-1500 and ANSI Z88.2). An
improper facial seal may allow contaminants to leak
into the facepiece, reducing or eliminating respiratory
protection. Do not use this device if such conditions
exist. The face-to-facepiece seal must be tested
before each use. Never remove the facepiece except
in a safe, non-hazardous, non-toxic atmosphere.
3. Open the cylinder valve
fully.
4. Place NightFighter Heads-Up Display System into
Continuous Operations Mode. Press and hold
Operation Button on transmitter for 3 seconds. Once
LEDs come on, release button.
Note:
The Continuous Operations Mode will deactivate if
a low battery condition is present.
INSTALLING PUSH-TO-CONNECT
MASK MOUNTED REGULATOR
Note:
Before donning, check that the regulator sealing
ring is seated properly in its groove, and that it is not torn,
gouged, or nicked.
1. Grasp regulator and
orient regulator so that
red bypass knob is
pointing to the right.
2. Insert regulator into
facepiece adapter by
pushing inward.
3. Ensure the regulator locks into facepiece.
4. Check proper engagement by pulling on the regulator
to ensure regulator is securely attached to facepiece.
