ed as an ignition source in flammable or explosive
atmospheres by MSHA/NIOSH.
N -
Never substitute, modify, add, or omit parts. Use only
exact replacement parts in the configuration as speci-
fied by the manufacturer.
S - Special or critical User's Instructions and/or specific
use limitations apply. Refer to User's Instructions

TIONS for the Respirator.
S - SPECIAL OR CRITICAL USER'S INSTRUCTIONS
1. Misuse or abuse of the NightFighter Heads-Up Display
System, the ICM Tx Unit, or the equipment to which
they are attached, or using this equipment in a manner
or situation not intended by the manufacturers, may
result in damage to the equipment or may result in
personal injur
y or death to user or persons dependent
on the user.
2. Always inspect the NightFighter Heads-Up Display
System and ICM Tx Unit for damage befor
e use. If
damage is found, immediately remove the device from
service.
3. When NightFighter Heads-Up Display System is used
as a gauge (Not in conjunction with standard pneu-
matic gauge) continuous operation mode must be
used to maintain NIOSH appr
oval.
4. Do not alter these components. Altering will void the
Intrinsic-Safety rating and may affect the Intrinsic-
Safety of the device.
Note: The NightFighter Heads-Up Display System
Receiver is for use with an Ultra Elite
®
Facepiece only. It
cannot be used without the proper installation of the
Receiver, Facepiece Bracket and either NightFighter
T
ransmitter or ICM Tx Unit fr
om MSA.
5. The NightFighter Heads-Up Display System allows a
user to clearly and easily see air cylinder content while
wearing an SCBA equipped with the Ultra Elite
Facepiece.
Note: The NightFighter Heads-Up Display can only be
used with an Ultra Elite Facepiece.
6. The NightFighter Heads-Up Display consists of three
(3) separate assemblies:
• Bracket assembly attached to an Ultra Elite
Facepiece.
• Receiver mounted on the bracket assembly.
• ICM Tx Unit or Transmitter assembled to the gauge
line. (See Installation Instruction P/N 10035581,
transmitter only).
7. The NightFighter Heads-Up Display System's Receiver
shows the user the air cylinder content in one quarter
cylinder increments, from a full cylinder to an empty
cylinder, by an LED light pattern.
8. The NightFighter Heads-Up Display System's
Transmitter is assembled to the gauge line hose. (The
ICM Tx Unit serves as the transmitter). The transmit-
ter sends a signal to the receiver (on the facepiece) of
the air cylinder content.
9. The NightFighter Heads-Up Display System's Receiver
has seven (7) LEDs that are used to form light pat-
terns.
10. The NightFighter Heads-Up Display System's
Receiver has a photo sensor for the LED lights to
automatically adjust the brightness of the LED based
on to the brightness as measur
ed outside of the face-
piece.
11. The NightFighter Heads-Up Display System's
Receiver will indicate a low battery by a Y
ellow LED
light for the receiver, ICM Tx Unit, or NightFighter
Transmitter.
The NightFighter Heads-Up Display System operates
using (4) standar
d AA alkaline batteries in the ICM Tx and
(2) standard AA alkaline batteries in the r
eceiver
. When
using a Nightfighter Heads-Up Display System with stan-
dard Transmitter (2) AAA alkaline batteries are needed.
The NightFighter Heads-Up Display System notifies the
user when the batteries need to be replaced.
Use only Duracell MN2400, Energizer E92, or Eveready
A92 AAA alkaline batteries in the TRANSMITTER. Use
of other batteries, or a combination of batteries from
different manufacturers, will affect the performance of
the unit and will void the Intrinsic Safety Appr
oval.
