Scantronic 9800 Is Nvm Procedure Correct

Hi all,

I have the Scantronic 9800 Installation Guide (496334 Issue 1)

Is the procedure in it on page 12 for refreshing the NVM actually correct i.e. it is done with power on to the the PCB?

(seems unusual to "hot flash" a chip like that)

The procedure in the manual is also slightly different to that written inside the case.

Basic issue: battery failed. Replaced with new one from Maplins. Now nothing works. Nothing else changed.

Yes, battery polarity correct and NVM chip is in the correct way round.

Regards,

Neil

Can't give you defualting information mate, but I will say that Scantronic documentation is normally good.

And I have had it a couple of times when the NVM wouldnt default and the chip needed replacing. The information on page 12 of that manual is correct.

The opinions I express are mine and are usually correct!

(Except when I'm wrong)(which I'm not)

Hi all,

yes the procedure in the manual is correct. It is working now.

Issue was that the chip was not seated properly the first time.
