3.8 Changing the display mode
Your camera has 3 display modes. You can switch between display
modes to help you see more clearly in different environmental
conditions.
To adjust the display mode:
1. Press the Display mode button once.
One of the following icons is displayed for a few seconds,
indicating the current display mode:
Display icon Display mode
White hot — hotter objects appear as white
or light grey.
Black hot
— hotter objects appear as black or
dark grey.
Marine red — similar to the White hot display
mode, but the hottest objects in the scene are
colored red to maintain normal night vision.
2. To select a different display mode, press the Display mode
button again.
Subsequent button presses will cycle through all 3 display
modes.
Note: While White hot is the most commonly used and visually
intuitive way of viewing thermal images, Black hot can enhance
the contrast of certain objects, or provide better visual perspective
in some conditions.
