Razer Nari Ultimate - Random Beeping (Beeps 5 times)

Recently developed a weird problem with my Nari Ultimate headset It seems to beep 5 times in quick succession at random intervals. When it does this there doesn't appear to be any interference with other sound, music doesn't cut out when it happens. Just started in the last 24 hours and is very annoying! Does anyone else have this issue or know what could be causing it? So far have removed drivers and reinstalled software and no change. Thanks in advance for responses.
