suggested reflashing

Manuel S ran into some trouble. Somehow the NexStar hand controller of his brand new CGEM went into programming mode! It showed "Transmit Data" as soon as it was turned on. They asked for my help but I didn't know what to do, off the top of my head. I suggested they review the documentation.

I wondered how that happened... Had they stumbled into the firmware update menu?

When I saw Manuel S just standing there later, not doing anything, not able to do anything, I offered to conduct some web searches. He accepted. I quickly found a note on the Celestron support site that recommended reflashing the hand controller. Manuel S felt inspired and said he would try. Turned out he in fact had the hand controller programming cable in his car. (Is that so?!) He set about fixing it.
