Am I the only one? 41-CX clock question

[Garth Wilson]

My cx Halfnut loses the time and date perhaps once a year, but not when removing the battery pack to change the batteries. It's clearly from a less-than-perfect connection reaching the piggy-back board it's on, and then the calc won't turn on either. I beat the side of the calc against the heel of my hand and that restores it, probably by causing some self-cleaning wiping motion of one contact surface against another. To recover more quickly when I don't always remember the right instruction words or their exact spelling, I wrote a 9-step program to prompt me for the time and date and set them, and I assigned it to a key. I use the cx's time capabilities every day. I wouldn't think of being without them.
