Hello,

I have recently received a HP 11C with almost flat batteries. When I turned the calculator on, the display was "0.0000". When I started typing in numbers, I have noticed that the numbers that I've typed were masked with "0.0000".

For example:

If I want to type in "12345678.0", the calculator displays:

"0.0000678"

therefore the first 5 digits are replaced by the "0.0000" mask.

I took the batteries from HP 11C and placed them in my HP 15C. On the HP 15C side, the asterisk sign at the lower left hand corner of the screen started blinking. However, there was no blinking asterisk on the HP 11C side.

I would like to know if there is a version of HP 11C without the low battery indicator or is my HP 11C acting strange?

Thanks in advance,

Onur
