Problems related to Headphone

  • If you need to listen Bloomberg news or other videos (e.g. BMC), connect your headphone to audio port on the computer, not to the Bloomberg keyword. 
  • Check the volume setting (Windows Start > Control Panel > Hardware and Sound).
  • Reboot the Bloomberg Terminal if the problem still exists.

No Python on Library Bloomberg Terminals

Bloomberg stringently controls whether Python can be used to extract data from Bloomberg. Basically, we’re not allowed to do so. If necessary, use Bloomberg Excel Add-in instead. For assistance, feel free to email our Business Librarian, Celia Cheung ( or Kevin Ho (
