The 8 digit displayed number is rounded to within ±1 in the 8th digit for all functions except where noted. Battery installation and Considerations The TI-30 operates on a 9 -volt non-rechargeable battery. which is not supplied with the calculator since its freshness cannot be ensured. An alkaline battery is recommended for your calculator. It has an operating life of approximately 20 hours. A non-alkaline battery may be used but it should be removed prior to a prolonged period of non-use or immediately after discharge to prevent possible damage to the calculator from leakage. When the battery becomes discharged. the display becomes dim or may flash or show erroneous symbols and numbers just before fading away. 3
