Operating Your Camera (cont’d)
GAIN Adjust
A higher gain setting raises the sensitivity of the
camera and provides more contrast on background
features. A lower gain setting lowers the sensitivity
and provides additional detail in hotter objects.
LEVEL Adjust
The level setting may be used to change the
apparent video level of the image seen in the
viewfinder (and through the RCA video jack). A
lower level setting while in white hot (WH) mode
also allows a higher gain setting to be used without
saturating hot objects on the display.
Polarity Control
The polarity control is used to control whether
warmer items in a scene appear as white (WH) or
black (BH).
Electronic Zoom
The electronic zoom is used to “zoom in” on an
image using the camera’s electronics to magnify
the central region of the image. The zoom ratio is
2:1 when ZM2X is displayed and 1:1 when ZM1X
is displayed.
FOCUS Adjust
For models with motorized focus lenses, the
ADJUST buttons are used to focus the lens. The
ADJUST buttons are active for FOCUS when the
menu is blanked and when the menu is visible
with the cursor on FOCUS. As a reminder, if the
menu is visible and the cursor is over another
function, the ADJUST buttons control that
function, rather than FOCUS.
Brightness Control
The brightness control is used to set the internal
viewfinder’s intensity. Set this to any level
comfortable for viewing.
