in the Picture Profile menu and set the shutter
speed according to the power supply frequency.

Set the shutter speed to 1/50 or 1/100 seconds.
When the frequency is 60 Hz
Set the shutter speed to 1/60 or 1/120 seconds.

Using the Flicker-Reduction function
Set "Flicker Reduce" (page 46) in the Picture
,
Profile menu to "Auto" or "On" and set
"Frequency" to the power-supply frequency (50
Hz or 60 Hz).
Notes
• If the frame rate selected for recording is close
to the power-supply frequency, flicker may not
be reduced sufficiently even if you activate the
Flicker-Reduction function.
• Flicker cannot be corrected when the recording
frame rate and the shutter speed are not integral
multiples of the power frequency.
