2.12 Eyepiece shutter
Close the eyepiece shutter when there is a strong light source behind
the camera or when pressing the shutter release button without looking
through the viewfinder.
(This prevents exposure error due to light entering from the
viewfinder.)
Turn the eyepiece shutter lever in the direction of the arrow.
2.13 Setting date and time
Date and time is set and controlled through the digital back.
Default date and time is GMT+1.
If the digital back has been without power for a longer period of time,
it will automatically ask you to setup time and date when it is powered
up.
In the “Time & Date” menu you can set the time and date using the four
buttons on the P+ back. Left side buttons will step through the hours,
minutes and seconds field, while the right up and down buttons can be
used to set the value of the fields.
The time and date is applied to all files captured with the P+ back.
