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 TRANS-
MITTER. Use of other batteries, or a combination of
batteries from different manufacturers, will affect the
performance of the 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.
Replacing the Batteries in the ICM Tx Unit
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
the unit and will void the Intrinsic Safety approval.
Failure to follow this warning can result in serious per-
sonal injury or death.
1. Loosen the four screws from the battery compartment
of the ICM Tx Unit.
2. Remove the batter
y cover (two scr
ews if Nightfighter
Transmitter is in use).
3. Insert the four AA batteries following diagrams inside
battery compar
tment (two AAA batteries if Nightfighter
Transmitter is in use). Insert each battery base firmly
into the case, then pr
ess down and in on the top of
the battery.
4. Verify that the battery cover gasket is held in place
and is free from damage and debris and is not twisted
in the gasket r
etention groove in the battery cover
.
5. 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.
6. Replace the cover. Make certain that the battery
cover is oriented properly. Align the angled tabs near
t
he battery cover screws with the battery cover.
C
heck that the rubber cover is no bunched or pinched
u
nder the battery cover; otherwise the battery cover
may not remain water tight.
7. 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.
8. 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.
