Quick Start Guide


Charge the FLIR ONE Pro with the included USB-C power cable connected to a 1A power source. The Charge Indicator LED next to the USB-C connection blinks on and off while the FLIR ONE Pro is charging and stays on continuously when it is fully charged. It will take about an hour to completely charge your FLIR ONE Pro. Ensure the FLIR ONE Pro is fully charged before using it the first time. Note: The power cable for the iPhone (with a Lightning connector) will not work to charge the FLIR ONE Pro iOS model.


Download and install the FLIR ONE app, which is available on the Apple App Store and Google Play Store. When you start the FLIR ONE app, the first-time User Guide will help you get started with the FLIR ONE. 


Press the power button on the bottom of the FLIR ONE to turn it on. The indicator light will turn orange. It will flash green when the device is ready. If needed, adjust the blue dial of the OneFit™ and extend the connector to the appropriate length to fit through your smartphone’s protective case. Connect the FLIR ONE to your smart phone and start the FLIR ONE app. You will be asked to create a user account with your email address and a password.
