N-Scan Craziness

Any assistance on any of the topics below would be greatly appreciated:

1. Clearing delivered messages from the Scanner Profile.

So, we use this feature most specifically with confirming our ADA seats are being used as per the law and not being scalped in what is a difficult environment regarding the free tickets at Shakespeare in the Park.  Regardless, since we have upgraded to V11 we have been unable to close messages from the hand held and the simply return for every ticket that is scanned under the constituent the message was created for.  I have confirmed that is not user error and the "Mark Read" button is being used, vs. the "X".  Our Tessitura IT Director has confirmed that everything is pointing in the right direction, but we are still having no luck with it.  We have also put in a ticket, but have gotten no response as of yet.  I am considering that it could be a set up point in our LTR_NSCAN_DEFUALTS table, but my concern is that every organizations table would appear different according to the organization.  Or is this a generic table with the same matching information, excluding of course "USE CUSTOM BIO PROCEDURE" and "USE CUSTOM SALES PROCEDURE" which would definitely be site specific.

Our table looks like this:

2.  We use the Motorola Model MC75 scanner and have been encountering the following issues:

• Device settings that are frequently putting our scanners to sleep during use, I have tried everything setting wise, but I have not found the right combination yet.  If anyone has the best answer please help.
• We are experiencing issues with maintaining our Wireless connection even during 4 bars present, is there a setting or something that I may be missing?  Granted we are having our WAP completely reinstalled both at The Public and The Delacorte (outdoor venue) to new Cisco hardware which will go live on Tuesday, but that is the first day of the park performances.  This issue was present intermittently well before this change over.  We would be scanning smoothly for 4-5 minutes and then with a lull of a minute or more and suddenly it was the dreaded "Working" and then finally "Device Can Not Access Server".
• Has anyone had any success with installing an NTP program on the scanners to keep date and time in sync. We have attempted to use the Scan Offline feature recently and because the scanner was not set to the right date and time of the event Tessitura will not accept the scans now, it returns errors that is either "For Another Performance" or wrong date and time.  I have been told this shouldn't be an issue in trainings in the past, but it is definitely an issue.
• Finally, when doing a reset on our scanners by restarting them using the red power button, which again I was trained to do by NScan.  Our scanners are hitting the Motorola screen, the windows screen and then going to a blank or black screen.  Nothing, we can't see anything.  In the end the only way to fix this is a battery pull.  Which in turn resets the date and time back making offline scanning useless, but without doing it the entire device is useless.

These are all very new issues for us, because out of the box we were scanning away.  Now a year later and an upgrade to V11 and we are ripping again on most of our shows only to find a scanner that works later and then the system is mainly an attendance tool, not an actual extension of Tessitura and a great CRM Tool.  I fear that in our change over into N-Scan and the need to keep costs low there were points missed between a changing of IT guard and skipping installation and training from N-Scan themselves.  Everything was self-installed by the IT department.  Any help that anyone could offer on these topics would be EXTREMELY appreciated.
