Operation
ICU-1 Battery LED
• Replace the battery when the battery LED (labelled BAT)
illuminates or flashes.
Do not start any new scenes!
• Immediately replace the battery when the battery LED
flashes. Otherwise, you run the danger of deep
discharging the battery.
The battery LED reacts to the following voltage limits:
Main Voltage BAT Indicator Actual Voltage
24V illuminated < 20 V
flashing < 18 V
12V illuminated < 10 V
flashing < 9 V
ICU-1 Main Fuse
The main fuse is a self resetting thermal fuse. If it blows due
to an error, remove the cause of that error and let the fuse
reset itself. Under normal conditions it will reset in five to
ten seconds. High outside temperature or a severe error
will prolong the resetting time.
Note: If you suspect a blown fuse while using the ICU-1
with the ARRIFLEX 535A, 535B, or early models
of the 16SR 3, make sure to also check the
camera’s accessory fuse!
Later models of the 16SR 3 and the 435 are
equipped with self resetting thermal fuses. The
same method for resetting applies.
Button Lock During Run
The ICU-1 will lock all buttons while the camera is running.
If a locked button is pushed, the ICU-1 will show a red
LED as long as that button is pushed.
