[DW PRO1 DISCONTINUED]
If a Customer would like to update their firmware, please send them the following link:
They will then head to the Sennheiser Updater heading and click Download End User Version.
Then, they click the second blue link, Download Sennheiser Updater.
For this to work, the Customer must have their OfficeRunner hooked up to a computer by USB.
Unfortunately this does not work on Mac computers.
If they need help further than this, please get them to Product Support.
