switch between the 2 camera lenses.

Thermal camera scene presets
Scene presets enable you to quickly select the best image setting
for the current environmental conditions.
During normal operation the thermal camera automatically adjusts
itself to provide a high-contrast image optimized for most conditions.
The Scene presets provide 4 additional settings that may provide
better imagery in certain conditions. The 4 modes are:
234
Night Running — scene preset mode for night conditions.
Day Running — scene preset mode for daytime
conditions.
Night Docking — scene preset mode for night docking.
Search — scene preset mode for identifying people or
objects in the water.
Although the preset names indicate their intended use, varying
environmental conditions might make another setting more
preferable. For example, the night running scene preset might also
be useful while in a harbor. You may find it beneficial to experiment
with the different scene presets to discover the best preset to use
for different conditions.
Changing the thermal camera scene preset
In the thermal camera application:
1. Use the SCENE softkey to switch between the available scene
modes.
The "scene" icon changes to reflect the current scene mode.
Thermal camera color modes
A range of color modes is available to help you distinguish objects
on-screen in different conditions.
The COLOR softkey switches the thermal camera image between
a greyscale mode and 1 or more color modes. There are 5 color
modes available.
