OPERATION.
2.9.1.
Figure 2-7. The Controller Unit and Detonator Unit vents are manual and
relieve internal pressure due to heat and altitude. When the vent is closed, it will not
leak in 100 feet of water or up to 30,000 feet in altitude.
CAUTION
Unequal air pressure inside the Controller Unit may affect the operation
of membrane switch keypad. Extreme pressure differentials may irreversibly damage
the keypad and/or cases.
CAUTION
Vents in all units should be momentarily opened and closed immediately
before use.
CAUTION
Do not open a vent if there is water on or near the vent. Take necessary
precautions to ensure water does not enter the vent.
