Well, believe it or not, we fixed something similar at a customer in Spain (sunny Spain) some time ago, using some "special hardware". Imager was saturated and just could not decode anything. Aiming dot was NOT the issue then. First, get some sunglasses. I mean it, really... Just put one lens in front -very close, even touching- of the imager window and try and decode. If this works, we can go further; if not, this is not the same type of issue I coped with, so forget about the rest. In some specialised stores you can find "smoked" transparent paper/film (or, even better, polarised paper/film! the same it's used for 3G glasses). If terminal is to be used only under heavy sun conditions, you may simply glue a piece of this material to the imager window. If not, you or you partner will have to devise some sort of folding mechanism to be able to physically "enable" or "disable" this "feature". My partner did so, at least a prototype I can remember. I hope this helps!

Thanks for this information. Was the partner and customer trial successful? Did they roll it out? Do you have any details on the polarized paper they used? Andy

The MC-75 uses the SE-44xx Pico imager; it does not support an aim dot. There are no settings to adjust the aim pattern other than to turn it on or off.  The aim pattern is fixed to the hardware. There was a version of the MC-7094 w/GPS that used an aim DOT pattern instead of the crosshair/bracket. The MC-75A uses the SE-4500 Blockbuster imager.  The aim pattern is a large + sign with an aim dot in the center that works much better in bright sunlight than the SE-44xx pico imager. Is the lack of a visible aim pattern the main issue?
