Thermal and visible-light operation
“Dual payload” thermal cameras are equipped with
2 cameras — a thermal imaging (infrared) camera
and a visible-light camera.
Thermal camera —
provides night-time
imagery, based on
temperature differences
between objects.
Thermal imaging
produces a clear image
even in total darkness.
Visible-light camera
— provides black and
white (or greyscale)
imagery during the
day and in low-light
conditions. Helps to
improve navigational
abilities in low-light
conditions; for example
during twilight hours
when operating along
intercoastal waterways
and near harbor
entrances.
Note: The T470SC
and T473SC have
a color camera and
continuous zoom
lens.

camera lenses

1. Select
Menu .
2. Select Image Options .

Thermal camera rear view mode
The rear view mode flips the video image horizontally,
providing a “mirror image”.
This is useful for example in instances where the
camera is rear-facing and you are viewing the image
on a forward-facing monitor.

Slew to Cue
Slew to cue is a feature which maintains a selected
position or object in the thermal cameras field of
view. Slew to Cue options are available in the chart
and radar applications as target context menu items.
Note: Heading data must be available on the
system for Slew to Cue to work correctly.
For details on how to select a target to ‘slew to’ refer
to the radar and chart sections of your manual.
The thermal camera can also automatically slew to:
• MOB target

Options to enable or disable the automatic slew
options are available in the thermal camera
