pulsar calculator 901

[Kasper]

after 15 years, i decided for the first time to put some batteries in my pulsar 901 calculator. yeah i know..to many watches and this is not a daily wear watch. I always tough that she was working.

So after putting fresh batts in it..the only thing that works is the calculator. so pressing 0 does the job and all other digits works.
If i press the pulsar command button..the calculator digits goes away and the screen is blanc...nothing anymore..so the command button works but why can i not see the hour or date?

Anyone an idea??
thx

Hi to you all
I have a little question on the side . I just would like to know if the calculator modules in the american and european modes are the same .Do they fit each other?

Yes, all Calculator modules are physically interchangeable. You just have to be careful about re-arranging the keyboard keys to match the version you are installing (reversing the positions of the "C" and "=" keys, and the positions of the "R" and "S" keys, depending on whether a 901 or 902/3 module is going in). DON"T open a Calculator (or any other Pulsar, for that matter) unless you are electrically grounded (or it's a rainy, high-humidity day, to eliminate any possibility of introducing a static charge into the electronics...something that may have killed as many modules as leaking batteries), and NEVER set an uncased Calculator module face-down on any surface, or you can kiss most of the display wire-bonds good-bye.
