I recently purchased a HP41CV Blanknut from a guy who said it had been stored away for the last 15 years.
The buttons have a nice feel to it, but I have a problem with the on/off switch.
It is not as soft as the user/ alpha or program keys.
Could I spray it with something?
Or will it have to be opened?
thanks,
Iqbal
