4-17. [F9]: DC Jack Voltage Adjustment

(note)
1) When adjusting the DC jack voltage, supply power
(5V) to the camera from the [Specified Power Cable
Jig] before setting the jig mode.
2) Always measure input voltage in the vicinity of the
DC IN terminal.
3) When reducing the voltage, adjust the stabilized pow-
er supply to ensure that the voltage is not reduced ex-
cessively from the measured point. The adjustment
software may produce an error if communication be-
tween the adjustment software and the camera is dis-
rupted. Restart the adjustment software in this case.
<Step 1>
