What type of battery does the stethoscope use?
• The stethoscope was designed to accommodate three battery types to fit your needs. Use one AA Alkaline, Lithium, or NiMH battery to operate your electronic stethoscope. The default battery type is Alkaline. Therefore, if using either a Lithium or NiMH battery, you must change the battery type within the setup menu of the electronic stethoscope for a reliable battery life indication on the display screen. The Lithium battery is a non-rechargeable cell that is recommended for low-temperature operation of the stethoscope and generally has a longer life than an Alkaline battery. The NIMH battery is rechargeable battery (external charger required).
