MY PRODUCT ISN'T WORKING
CHECKING BATTERY CONTACT
Make sure your battery(ies) is inserted correctly. If the battery(ies) are inserted properly and good contact is confirmed, and your product is still not working, the battery(ies) may be weak and in need of replacement. Weak batteries may also cause errors.
Where can I purchase batteries?
Most CI products use long-lasting lithium batteries (commonly used for watches) which you may purchase at any Radio Shack or consumer electronic retail store.
CALCULATOR WILL NOT OPERATE
My calculator simply won't turn on, or locks up. What should I do?
Use the end of a paperclip (or a tool of similar size) to press the "Reset" hole which is typically located at the front of the calculator, below the display (on the right or left side) or at the back, bottom right-hand corner. Your calculator should then turn on.
Clear All/All Clear/Reset
How do I perform a Clear All (or All Clear) or Reset?
For most dimensional-based (e.g., Construction Master) CI calculators, press the Convert key and then the "x" (multiplication) key ([Conv] [x]).
If you own a Real Estate Master IIIx, Qualifier Plus IIIx, Qualifier Plus IIIfx, Mortgage Qualifier Plus, ElectriCalc LT, ElectriCalc Pro or others, press the Set and then the "x" (multiplication) key ([Set] [x]).
