It's about time for a v. 3.3 PDF manual. Since June 2014, to be exact.

Ok, let me summarize as I understand it:

• The WP 34S HW & FW as available in the net (various sources) requires some invest.
• Powering it costs some money for batteries.
• The comprehensive information to operate it shall be free?
  

Just want to make sure I didn't get you wrong.
