REPLACING THE BATTERIES

Replacing the Batteries in the FireHawk M7 HUD
Replace the batteries in the FireHawk M7 HUD or I-HUD
when the low battery LED flashes. Use only recommended
battery types. Change the batteries in a non-hazardous area
only. Misuse can result in serious personal injury or death.
1. Unthread the battery cap (counter-clockwise) on the
FireHawk M7 HUD battery tube.
2. Remove the battery cartridge from the FireHawk M7 HUD.
3. Remove the batteries and discard.
4. Inspect the battery cartridge for signs of damage such as
corrosion on the battery terminals or cracks in the car-
tridge. If the battery cartridge is damaged, replace the car-
tridge immediately.
5. Insert three AAA alkaline batteries in the appropriate loca-
tions on the cartridge. Follow the notations on the car-
tridge to ensure proper battery orientation.
Use only Rayovac 824 LR03, Rayovac Ultrapro LR03,
Energizer E92, Energizer Industrial EN92, Duracell MN2400,
or Duracell Procell PC2400 alkaline batteries in the FireHawk
M7 HUD. Use of other batteries, or a combination of batter-
ies from different manufacturers, will affect the performance
of unit and void the Intrinsic Safety Approval.
6. Insert the battery cartridge into the battery tube on the
FireHawk M7 HUD.
7. 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 mois-
ture or contaminants into the battery tube and cause the
device to not function properly.
