13. FEATURES OF THE CAMERA SECTION
This switch allows the gain to be boosted when the illumination
of the subject is insufficient.
The gain should be switched when the brightness is insufficient due to poor lighting conditions.
GAIN SWITCHING
When the GAIN switch is switched, the newly set gain is
displayed for about 2 seconds on the Status 0 or Status 1 screen
in the viewfinder.
Set it to L (0 dB) in normal use.
The gain set for each of the switch positions can be changed
with "GAIN" on the OPERATION MENU screen.
It is also possible to use the ALC function that varies the gain
automatically.
See page 73 for details.
To make the gain transition smoother, set “SMOOTH TRANS”
on the OPERATION MENU to “ON”.
See page 73.
However, note that the SMOOTH TRANS function is not
available if gain is set to ALC.

L 0dB
M 9dB
H 18dB
The LOLUX button is used when the illumination is still
insufficient after compensating with the GAIN switch.
Press the button to enter the LOLUX mode in which the gain is
boosted by about 33 dB.
"LOLUX ON" is displayed for about 2 seconds on the Status 0
or Status 1 mode screen in the viewfinder.
Pressing the button again cancels the LOLUX mode.
"LOLUX OFF" is displayed for about 2 seconds.
When the LOLUX function is in use, the image definition on
the screen will degrade to increase residual images, but this
is not a malfunction.

13-4 Gain (Sensitivity) Adjustment
When gain is set to "ALC", gain is boosted automatically
as the illumination becomes darker. However, noise will
increase a little because the screen becomes brighter as
the ALC (Auto Level Control) function boosts the gain more
than in the case of manual adjustment.
