About Sounds
DynaFlex II Go products have a beeper that provides feedback to operators and cardholders about the
internal state of the device:
•
The device sounds one short beep after it has successfully read a contactless tap, and the cardholder
can safely remove the card or device from the contactless landing zone.
•
The device emits two beeps when reading a card or contactless payment device to indicate a card read
error occurred.
•
The device sounds two beeps when an operator cancels a pending EMV transaction.
The device provides an internal setting the host can use to adjust the global system volume. The device
does not provide an interface to change the volume setting directly via buttons. If the device is too quiet
or too loud:
•
Make sure the device is being ordered from the manufacturer with the desired volume setting.
•
Check to see whether the host software you are using provides a feature to check and/or adjust the
volume setting.
•
If the host software does not provide that feature, request help from the development team that built
the host software to check / change the volume setting. For details, see
