Hi Paul,
Yes, it is now reporting Batteries OK, but I bough 8 x 3900MAh NiMh batteries to make a spare pack, just in case

Now...... Had I known, I didn't need to buy "Beetle Mouse" just to get at the Icon's with the Screen Cal way off, it turns out GENRAD thought of that scenario..........
If you press the red "off" button twice in quick succession it enters Screen Cal Mode, DOH !!
Should have read the Manual first lol.
Still it will be handy having a working Keyboard and Mouse

Cheers Dave
