- A steady blue LED on one Vscan Air Probe side indicates which transducer is active and selected. Vscan Air CL is powered ON.
- A steady purple light on both LEDs indicates the Vscan Air Probe is ON, is occupied and shall not be interrupted. E.g. when running test or upgrading software.
- A steady red on both LEDs indicates the Vscan Air Probe is ON and an error has been detected
NOTE: The steady blue LED will light up in a brighter blue color when scanning compared to when scanning is halted. i.e., in Freeze. Indicating that probe now saves power while not scanning. The Vscan Air probe will switch itself off when the battery capacity drops 17% from the charge level probe had when it was left connected to the app in Freeze.

1. No light indicates that the Vscan Air probe Storage mode is enabled for one of the below reasons:
- A new not yet used Vscan Air probe arrives with Storage mode enabled. Before starting to use the probe, it has to be activated as described in the section Vscan Air Probe activation
- The Vscan Air probe will automatically enter Storage mode when the probe charge level is <8%. The probe will need to charge to a level above 8% to accept being powered on.
- The probe can also have been put into Storage mode as described in the section Storing devices in between uses
NOTE: To re-activate the probe, the probe needs to be placed onto the wireless charger. When the probe has been re-activated it can be turned ON and battery status can be checked via the short press (<1 sec) as described in this section.
2. A steady yellow light on both LEDs indicates a Vscan Air Probe charge level in the range 8-90%.
