About Sounds

DynaProx 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 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 D998200489 DynaProx
Programmer's Manual (COMMANDS).

Blinking LEDs generally mean the device is in the process of doing / attempting
something. Blink duty cycle and blink period are generally selected to show
urgency or ongoing progress through a series of steps.
Example: Device is attempting to connect to the 802.11 access point.
LEDs sometimes light for a short time to indicate some process has ended
(success or failure) and the device is going to transition to another state soon.
Example: Successful card read.
