The red colorization in high-gain mode (–20 to +150°C) is confusing: red for a fireman means danger. How do I remove it?

In order to remove the red colorization, your FLIR K45, K55, or K65 must be running firmware version 2.7.12.

You can update your camera firmware by using FLIR Tools or download the standalone firmware update from our download page. Note that this firmware release is already installed on new cameras.
