Key Details on the HP39gII

One of the really clever features of the HP39gII is that you can easily update the operating system. To do this you download the updater software, connect your calculator to your computer and in about 20 seconds, it’s done. Go to the hpgraphingcalc site and download the updater zip folder. make sure to keep it all together in the folder and look at the read me file. Follow the instructions and you’re done. Here. There will be regular updates. The latest is version 1.3 which contains the StreamSmart data streaming app. We are hoping for a computer algebra systems and dynamic geometry and various other new content, so it will be well worth making this a habit.

The HP39gII can be used in all exams where a calculator is allowed at GCSE and A Level. However, exam secretaries are sometimes worried that students will have put there own content on the machine and need a quick check that the calculator is exam ready. To do this you need to reset the machine:

  • Turn the calcualtor off.
  • Hold down F1 and F6
  • Turn the calculator on still holding F1 and F6.
  • Release everything when you see the HP logo.
  • You then get a clear visual confirmation that everything has been cleared.

The emulator has very clever features for configuring your best screen composition. On the ‘skins’ menu there are four choices for showing the calculator looking like a calculator. My favourite for a 4:3 projector is ‘Large’. However if you press the maximise button (the middle one of the group of three in the top right hand corner of the window), you get the calculator screen maximised with the buttons placed to the right. this is set up differently for each of the skins. My favourite here for showing the calculator screen as big as possible is the ‘medium’ skin maximised. Download the latest emulator regularly to make sure you are up-to-date, again, it’s here.
