About Sounds
DynaWave’s beeper provides feedback to operators and cardholders about the internal state of the device:
The device sounds one short beep on startup to test the beeper and indicate the device is powered on.
The device sounds one short beep after it has successfully read a contactless tap, and the cardholder
can safely remove the card or contactless device from the contactless landing zone.
The device sounds two beeps when an operator cancels a pending EMV transaction.
The device sounds two short beeps when it fails to read a nearby contactless card or contactless
device.
