REPLACING THE BATTERIES

WARNING
Replace the batteries in the HUD when it indicates a low battery
condition. Use only recommended battery types. Change the
batteries in a non-hazardous area only. Misuse can result in serious
personal injury or death.
When receiving a yellow low battery indicator, confirm the HUD
batteries are the root cause by verifiying the battery status of the HUD
Transmitter on the HUD Transmitter display. If the HUD Transmitter
battery icon indicates a low battery, replace the HUD Transmitter
batteries (located in the FireHawk M7/M7XT Power Module, the ICM
Tx/TxR, or the NightFighter Transmitter Module).
If the HUD Transmitter does not indicate a low battery on the display,
or the yellow light continues to flash after replacing the HUD Transmitter
batteries, replace the HUD unit batteries.
Replacing Batteries
1. Unthread the battery cap (counter-clockwise) on the HUD battery
tube.
2. Remove the battery cartridge.
3. Remove the batteries and discard.
4. Ensure that moisture or debris is not present in the battery
compartment.
5. Inspect the battery cartridge for signs of damage such as corrosion
on the battery terminals or cracks in the cartridge. If the battery
cartridge is damaged, replace the cartridge immediately.

6. Insert three AAA alkaline batteries in the appropriate locations on
the cartridge. Follow the notations on the cartridge to ensure proper
battery orientation.
WARNING
Use only Rayovac 824 LR03, Rayovac Ultrapro LR03, Energizer E92,
Energizer Industrial EN92, Duracell MN2400, or Duracell Procell
PC2400 alkaline batteries in the HUD. 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.
7. Insert the battery cartridge into the battery tube on the HUD.
8. Before installing the battery cap, verify that the o-ring is in place and
free of damage and debris. If the o-ring is missing or damaged,
replace o-ring. Failure to do so may allow moisture or contaminants
into the battery tube and cause the device to not function properly.
9. Thread the battery cap on to the battery tube of the HUD
(clockwise). Hand-tighten cap until snug. Do not over-tighten the
battery cap.
10. As the battery cap makes contact with the battery cartridge, verify
that the HUD display turns on and goes through its start
up sequence before turning off. The yellow LED should not be
flashing.
NOTE: Always test the HUD and the entire air mask to be sure that the
system operates properly before entering any hazardous atmosphere.
WARNING
DO NOT use this device unless it passes all inspection and
functional tests. Misuse can result in serious injury or death.
