The January 1992, April 2008 HP-12C and HP-15C CE (rewritten) manuals do detail the procedure on p17/p61 (ON and '.'). Correct? I know the self-test sequence changed.

FYI the self-test instructions for HP Voyager models can be found (in English) here

HP office supply has some other FAQ's about the Voyager models for those that can read English. I've no idea if there's Portuguese (Brazil) versions available.

I can

1. Perform calculations in algebraic and RPN modes.
2. Drive on either side of the road.
3. Speak/read/write international (UK) and North American "English".

However languages aren't my strong point. I once lived in a non-English speaking country. I never did learn the language.

1) Open the battery compartment and take/publish a photo. Is a POGO (programming) connector present?

2) Use g-ENTER-ON and record/publish the firmware version.

3) RESET the calculator if it has a button in the battery compartment or remove the batteries.

4) Run whatever TVM tests you wish and compare/publish the results.

5) If possible read the firmware out of the unit. If you don't have a cable etc try and find someone who can.

6) Open the unit and take a look inside. Take and publish photo's.

Be a detective. Document what you do. Photographic "evidence" can help others see details you might miss. Details details details!
