Did you power-on the calculator with f+ENTER+ON to invoke USB mode? (This only works with firmware 0A0Ah 2024-06-03), This isn't necessary when updating the firmware.

Thanks yes, that's all fine.

I think I have a battery problem related to my issues. I've had the calc one year, on the original batteries still running well. But, before starting the updates yesterday, I switched off and removed one battery to test it. Putting it back, all data had been lost, The other hadn't maintained the memory. This morning i tested both and found 2.7V and 3.3V. I'm suspecting one battery has never been connected? So I replaced the low one with a better one, at about 3.05 V

Now the calculator is showing itself as a 'USB input device' under 'Human Interface Devices' in Windows 10. No sign of anything called 'Voyager' as described in the instructions, either there on in Windows Explorer. Do we expect it to appear in file manager/win explorer in the same way as a USB stick or USB connected phone would?

Im assuming it should connect, provided the firmware and f/enter -on keys are pressed as instructed, without starting Voyagersave? Audible beeps are indicating that it is connecting and disconnecting as expected,

Anyway, Im backing off until I can get a new set of batteries.

Any insights will be appreciated.
