6. Check for bypass oper-
ation. Grasp the red
knob and turn it
counter-clockwise.
Listen for air flow.
Close the bypass.
There must be a continuous flow of air when the
bypass knob is opened. If not, do not use the appara-
tus. The SCBA must be checked and corrected for
proper operation by an MSA trained or certified repair-
person before using it. Failure to follow this precaution
may result in serious personal injury or death.
LEAK AND NIGHTFIGHTER HEADS-UP DISPLAY SYS-
TEM CHECKS
Note:
Continuous Operations Mode can only be activated
when SCBA is pressurized.
1. 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.
2. Close the cylinder valve fully.
3. Watch the NightFighter Heads-Up Display System
Receiver for 60 seconds. The LED light pattern must
not change.
If the NightFighter Heads-Up Display System
Receiver’s LED light pattern changes, do not use the
apparatus. The SCBA must be checked and corrected
for proper operation by an MSA trained or certified
repairperson before using. Failure to follow this pre-
caution may result in serious personal injury or death.
4. Crack the bypass valve slowly to bleed off pressure.
5. Watch the NightFighter Heads-Up Display System
Receiver while bleeding off pressure. The LEDs must
illuminate in accordance with the NightFighter Heads-
Up Display System decreasing pressure sequence.
NightFighter Heads-Up Display System Decreasing
Pressure Sequence
•
Four Green LEDs, Steadily ON.
•
Three Green LEDs, Steadily ON.
•
Two Yellow LEDs, Flashing Continuously.
•
One Red LED, Flashing Continuously.
If the NightFighter Heads-Up Display System fails to
illuminate in the decreasing pressure sequence, do not
use the SCBA. The SCBA must be checked and cor-
rected for proper operation by an MSA trained or cer-
tified repairperson before using. Failure to follow this
precaution may result in serious personal injury or
death.
Note:
The NightFighter Heads-Up Display System will
automatically turn itself OFF, approximately 60 seconds
after the apparatus is depressurized. (The single Red LED
will flash at this time).
DONNING THE FACEPIECE
Do not wear eye glasses under the facepiece. The
temples or sidebars on eye glasses will prevent an air-
tight seal. If you must wear glasses, install the specta-
cle kit. Failure to follow this precaution may cause
inhalation of contaminated air, resulting in serious res-
piratory injury or death.
1. Extend the facepiece straps fully. Place neckstrap
around your neck and don the facepiece by inserting
your chin first.
2. Pull the head harness
completely over your
head.
3. Tighten the lower (neck) harness straps first, by pulling
them straight back, not out.
4. Tighten the temple
straps the same way.
Tuck in the ends of the
straps so that they lay
flat across the head.
