1. Select \r\n the On/Setup button to access the DynaVox Setup Menu.
\r\n 2. Select Button Features.
\r\n 3. Below the OK button is the Usage Counts button.
\r\n a. If it says \"Hidden\" then the Usage Counts will not be displayed.
\r\n b. If it says \"Displayed\" then the Usage Counts will be shown.
\r\n c. Select the Usage Counts Option Ring once and it will toggle \r\n to the alternative option.
\r\n 4. Once the correct setting has been chosen, select OK to leave the Button \r\n Features menu.
