Note the following precautions: • Be sure that the positive (+) and negative (-) poles of each battery are facing in the proper directions. • Never mix batteries of different types. • Never mix old batteries and new ones. • Never leave dead batteries in the battery compartment. • Remove the batteries if you do not plan to use the calculator for long periods. • Never try to recharge the batteries supplied with the calculator. • Do not expose batteries to direct heat, let them become shorted, or try to take them apart. (Should a battery leak, clean out the battery compartment of the calculator immediately, taking care to avoid letting the battery fluid come into direct contact with your skin.) Keep batteries out of the reach of small children. If swallowed, consult with a physician immediately. u To replace the main power supply batteries • Never remove the main power supply and the memory back up batteries from the calculator at the same time. • Never turn on the calculator while the main power supply batteries are removed or not loaded correctly. Doing so can cause memory data to be deleted and malfunction of the calculator. If mishandling of batteries causes such problems, correctly load batteries and then perform the RESET operation to resume normal operation. • Be sure to replace all four batteries with new ones. Turning off the calculator while editing an eActivity and then changing batteries can cause the data you are editing to be deleted. Be sure to save the eActivity data before turning off the calculator and changing batteries. 2005604601
