Recommended Action
If cold, wait for built in heaters to
warm up the lens. If hot, the internal
temperature is too hot. If loss of
EOW camera impacts mission, turn
off system and allow to cool. If
problem persists, contact L-3
Wescam.
Verify that EOW sensor focus can
still be adjusted. If focus control loss
impacts mission, replace turret.
Execute a BIT from the Level 2 EOW
Menu. If failure persists, replace
turret.
Verify that EOW sensor focal length
can still be adjusted. If zoom control
loss impacts mission, replace turret.
Execute a BIT from the Level 2 EOW
Menu. If failure persists, replace
turret.
Verify whether EOW, when
configured in auto mode, can still
adjust to changing scene intensity
levels. If capability loss impacts
mission replace turret.
Execute a BIT from the Level 2 EOW
Menu. If failure persists, replace
turret.
Warning only. No action. Contact L-3
