when replacing the batteries (3 AA cells). When performing a probe zero function,
simply place the transducer on the disk making firm contact.
Important: Be sure to follow the polarity labels located on the back label of the PVX.
Note: Rechargeable batteries can be used, however they must be recharged outside
of the unit in a stand alone battery charger.
