Before you link your Philips monitor to Dropbox, make sure of the following:
The name of the monitor contains only numbers 0 to 9 and/or alphabets A to Z (or a to z, monitor names that contain other characters or symbols are not supported by Dropbox)
Your Dropbox account is not full. Generally speaking, around 500KB is needed for one audio recording. Clean up the Dropbox space regularly to make sure there is enough capacity for your audio recordings.
Make sure you have updated the software of the monitor with the latest version. Tap on “Monitor software” to start the upgrade process if there is update available.
