When Gain is set to negative values, or values higher than 3 dB, the gain indicator in the
viewfinder lights (only for ocular viewfinders).
The gain switch can also be used to vary the gain continuously between its minimum and
maximum value.
1. Hold the switch continuously in the up or down position until you see the value in the
viewfinder change in steps of 0.1 dB.
2. Release the switch when you reached the value you want. This exits the value selection
mode.
3. Using the switch momentarily again sets the gain to the nearest preset value.
