5.2.2.2. Panic button
The cPRO panic button is a unique feature of the cPRO / cPRO PLUS and cPRO ONE hand
unit. It allows you to override the mechanical hard stops without adjusting the predefined
focus range. E.g. when shooting the slate outside of the predefined focus range, or the
actor misses their mark.
In order to override the mechanical hard stops temporarily, simply press the panic button
and rotate the knob so it passes under the hard stop.
In order to disable the mechanical hard stops, press and turn the panic button clockwise
or counter-clockwise 90°. To re-enable the mechanical hard stops, press and turn the
panic button back to its home position.
