Adjusting your Scanning Beeps in your ECO2
If you are using your ECO2 with a switch but when your keys scan, they are beeping too loudly or you wish to not have any feedback at all, you can adjust this setting in the Feedback menu.
Go to the Scan Beep Feature:
Your options will be OFF and numbers 1 - 5. 5 being the loudest.
The default is set to 3. If you do not want to hear a beep, select the down arrow to OFF. If you wish to have a louder beep, increase the number to 5.
