DISPLAY CAPACITY AND ERRORS

Accuracy/Display Capacity — The calculator has a twelvedigit display made up of eight digits (normal display) and four fractional digits . You may enter or calculate values up to 19,999,999 .99 . Each calculation is carried out internally to twelve digits . Most material calculations will result in an answer rounded up two places . Press the = key to see the non-rounded value .
Errors — When an incorrect entry is made, or the answer is beyond the range of the calculator, it will display an error . To clear an error condition, press the On/C button once . At this point, you must determine what caused the error and re-key the problem .

If your calculator should ever “lock up,” perform a Reset by pressing a small device (such as the end of a paper clip) into the small hole located above and left of the Off key . This will perform a total reset of the calculator .

Auto-Range — If an “overflow” is created because of an input or calculation with small units that are out of the standard sevendigit range of the display, the answer will be automatically expressed in the next larger units (instead of showing “OFLO”) — e .g ., 20,000,000 mm is shown as 20,000 m . Also applies to inches, feet and yards .

AUTO-SHUT OFF
Your calculator will shut itself off after about 8 to 12 minutes of inactivity .

BATTERY
This model uses one CR2032 battery (included) . Should the calculator display become very dim, does not power on or remain on, replace the battery .
