Before replacing batteries, read the precautions outlined below. CAUTION: Improper handling may result in shortened life or in an explosion, and electro-static discharge may damage sensitive logic board circuitry. Observe ESD precautions to prevent damage to static-sensitive logic board components. DO NOT use excessive force when inserting or removing RTC batteries, axial leads, battery covers or connectors. Keep replacement batteries in original packaging until ready for use. DO NOT place a battery on any conductive surface, or expose a battery to excessive heat. Shortened life or explosion can result from mishandling!
