5. NFPA 1500 as well as ANSI Z88.2 and Z88.5 prescribe
SCBA inspections which are to be performed “After
each use” and “Monthly”. The ICM Tx Unit inspections
must also be performed during these SCBA inspec-
tions.
6. DO NOT PAINT the ICM Tx Unit or NightFighter
Heads-Up Display System Receiver.
7. Do not mark or etch the surface of the ICM Tx Unit or
NightFighter Heads-Up Display System Receiver.
Installing the Batteries Before Use
In continuous service, battery life will vary depending on
user conditions. The batteries are not rechargeable.
Use only Duracell MN2400, Eveready A92, or Energizer
E92 AAA alkaline batteries in the Nightfighter Heads-
Up Display System TRANSMITTER. Use of other bat-
teries, or a combination of batteries from different
manufacturers, will affect the performance of unit and
void the Intrinsic Safety approval. Failure to follow
this warning can result in serious personal injury or
death.
1. Loosen the screws to open the battery doors in the
Nightfighter Transmitter.
2. Insert two AAA batteries according to the battery ori-
entation noted inside the transmitter compartment.
3. Close the battery door and tighten the screws.
Use only Duracell MN1500 or Energizer E91 AA alka-
line batteries in the RECEIVER or ICM Tx Unit. Use of
other batteries, or a combination of batteries from dif-
ferent manufacturers, will affect the performance of
unit and void the Intrinsic Safety approval. Failure to
follow this warning can result in serious personal
injury or death.
Replacing the Batteries in the ICM Tx Unit
1. Loosen the four screws from the battery compartment
of the ICM Tx Unit then remove the battery cover (two
screws if Nightfighter Transmitter is in use).
2. Insert the four AA batteries following diagrams inside
battery compartment (two AAA batteries if Nightfighter
Transmitter is in use). Insert each battery base firmly
into the case, then press down and in on the top of
the battery.
3. Verify that the battery cover gasket is held in place
and is free from damage and debris and is not twisted
in the gasket retention groove in the battery cover.
4. Before replacing the battery cover, be sure that the
rubber cover on the ICM Tx Unit is properly engaged
with the plastic housing. The rubber cover has barbs
that hold it firmly against the plastic housing.
5. Replace the cover. Make certain that the battery
cover is oriented properly. Align the angled tabs near
the battery cover screws with the battery cover.
Check that the rubber cover is no bunched or pinched
under the battery cover, otherwise the battery cover
may not remain water tight.
6. Evenly tighten cover screws by moving in an X pattern
(for ICM Tx Unit) around the cover. Be sure to tighten
the battery cover screws enough to provide adequate
compression on the battery cover gasket to prevent
dirt and moisture from entering the battery compart-
ment. A torque of 6 in lbs is suggested. Do not over-
tighten the screws. Do NOT use a thread sealant on
the screws.
7. Dispose of, or recycle batteries in accordance with all
applicable federal, state, and local regulations.
Replacing the Batteries in the NightFighter Receiver
1. Loosen the screws to open battery door.
2. Insert two AA batteries (Duracell MN1500 or Energizer
E91) according to the battery orientation noted inside
the compartment. (Older versions of the NightFighter
Receiver use AAA batteries). The approved AAA bat-
tery is Duracell MN2400, Energizer E92, or Eveready
A92.
3. Verify that the battery cover gasket is held in place
and is free from damage and is not twisted in the gas-
ket retention groove in the battery cover.
4. Align the battery cover to the RX housing and tighten
the screws evenly from side to side. Be sure to tight-
en the battery cover screws enough to provide ade-
quate compression on the battery cover gasket to pre-
vent dirt and moisture from entering the battery com-
partment. Do not overtighten the screws. Do NOT use
a thread sealant on the screws.
5. Dispose of, or recycle batteries in accordance with all
applicable federal, state, and local regulations.
Battery Disposal/Recycling
Dispose of or recycle batteries in accordance with all
applicable federal, state, and local regulations.
DO NOT dispose of the battery in fire. It may explode.
Failure to follow this warning can result in serious per-
sonal injury or death.
