APPENDIX ACCURACY/ERRORS Accuracy/Display Capacity – Your calculator has a twelve digit display. This is 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. Errors – When an incorrect entry is made, or the answer is beyond the range of the calculator, it will display the word “ERROR.” To clear an error condition you must press the o button once.
BATTERY AND AUTO SHUTOFF Your calculator is powered by a single 3-Volt Lithium CR-2016 battery. This should last approximately 800 hours of actual use (1 year plus for most people). Should the display become very dim or erratic, replace the battery. WARNING: Please use caution when disposing of your old batteries as they contain hazardous chemicals. Your calculator is designed to shut itself off after about 8-12 minutes of non-use. Note: Values in memory or shown on the display will be cleared.
