Hello Ivan,
Thank you very much for the feedback. These are very good suggestions. We log all customer requests and implement them as we have time. Regarding point #2, in the lower left corner of the graticule you will see an uncalibrated message when the store through is not active. I realize this is not as convenient as a pressed button, but still serves a similar purpose and will hopefully help you determine when you need to perform another store-thru. Thank you again.
Regards,
A.J.
