The pack was cleaned with lint-free kimwipes and 99.9% isopropyl alcohol not too long ago. > Was this combination ever known to work?

Please see these: http://aaronsplace.co.uk/private/pics/rl02/scope.jpg http://aaronsplace.co.uk/private/pics/rl02/manual.png This was from TP2 on the R/W module. S2 is wrong, which is why I noticed that up was connected to down and down to up. Thanks, Aaron.
