9.2 Battery Considerations and Service
The rechargeable lithium battery is not user-serviceable. Please contact FLIR
support for service instructions: https://support.flir.com.
For best results, charge the battery immediately after seeing a low battery indication using the supplied USB-C cable (with an AC wall charger, not supplied). If the battery is allowed to fully drain, allow 2~3 hours before the
charging display appears after connecting to an AC charger. a full charge
(100%) requires 6 hours, a charge to 90% power requires 4 hours. Charging
through a PC USB port is not recommended.
If the camera is not going to be used for an extended period (> 3 months), it
should be charged to 70% then stored at room temperature and recharged
every 6 months. Failure to do so may result in a battery that cannot be recharged and that therefore will require service.
9.3 Reset the Camera
If the camera display freezes or if the camera in any way stops operating normally, press and hold the up and down buttons for at least 10 seconds. Release the buttons when the camera switches OFF. After the device switches
OFF, switch it back ON again to resume use. No data will be lost by resetting

A thermal imager generates an image based on temperature differences. In a
thermal image the hottest item in the scene appears as white and the coldest
item as black, and all other items are represented as a gray scale value between white and black. It may take some time to get used to the thermal imagery. Having a basic understanding of the differences between thermal and
daylight cameras can help with getting the best performance from the camera.
One difference between thermal and daylight cameras has to do with where
the energy comes from to create an image. When viewing an image with an
ordinary camera, there must be some source of visible light (something hot,
such as the sun or lights) that reflects off the objects in the scene to the camera. The same is true with human eyesight; what people see is based on reflected light energy. On the other hand, the thermal imager detects energy
that is directly radiated from objects in the scene. Therefore, hot objects such
as parts on an engines and exhaust pipes appear white, while the sky,
puddles of water and other cold objects appear dark (or cool). Scenes with familiar objects will be easy to interpret with some experience.
Infrared energy is part of a complete range of radiation called the electromagnetic spectrum. The electromagnetic spectrum includes gamma rays, X-rays,
ultraviolet, visible, infrared, microwaves (RADAR), and radio waves. The only
difference is their wavelength or frequency. All these forms of radiation travel
at the speed of light. Infrared radiation lies between the visible and RADAR
range of the electromagnetic spectrum. The primary source of infrared radiation is heat, or thermal radiation. Any object which has a temperature radiates
in the infrared range of the electromagnetic spectrum. Even objects that are
very cold, such as an ice cube, emit infrared. When an object is not quite hot
enough to radiate visible light, it will emit most of its energy in the infrared. For
example, hot charcoal may not give off light, but it does emit infrared radiation,
which we feel as heat. The warmer the object, the more infrared radiation it
emits.
Infrared imaging devices produce an image of invisible infrared or ‘heat’ radiation that is unseen by the human eye. There are no colors or ‘shades’ of gray
in infrared, only varying intensities of radiated energy. The infrared imager
converts this energy into an image that we can interpret. The Infrared Training
Center (ITC) offers training (including online training) and certification in all aspects of thermography: https://www.infraredtraining.com.
