Signals are subject to change. Please refer to the online documentation and release notes for the
most up-to-date information on device signaling.
Status LED
●Off: device is powered down
●Breathing Blue: awaiting Bluetooth connection
●Solid White: connected to the app
●Slow Breathing White: ready to scan
●Fast Breathing White: performing measurement
●Solid Yellow: bootloader mode, waiting for firmware update
●While the device is charging, the LED will indicate charge status:
○Solid Green: 100%
○Green, pulsing: > 80%
○Yellow: 60-80%
○Orange: 20-60%
○Red: < 20%
Audio Signals
Beeps are used to communicate throughout the scanning process
●One beep: the scanner will beep at the end of each muscle group in the scanning flow to
indicate that it’s time to move on to the next muscle
●Two beeps: the scanner will beep twice if the button is pressed while the scanner is
unable to scan. This usually means the app requires attention before you can complete
the next scan
Please immediately stop using the Pact Sense upon experiencing any pain or
discomfort from the device. Use of the Pact Sense should be avoided on bruises,
contusions, rashes, or irritated or injured areas of the body until they are fully healed.
