General
4.4.1
The PHYSIO-PORT Recorder requires either two nickel metal hydride rechargeable batteries, or two
alkaline batteries.
When starting the recorder via the Physioportwin software, please ensure that the relevant power
source has been selected (see 6.6 Programming the recorder).
In addition, the device also has a built-in lithium cell to indicate the time. The capacity of two fully-
charged rechargeable batteries or two new batteries ensures at least 48 hours of operation or 400
measurements.
Battery capacity reduces in line with increased use. If the capacity of the two fully-charged rechargeable
batteries clearly falls below 24 operating hours, then you need to replace them.
Always insert two fully-charged rechargeable batteries or two new batteries, before taking a new
measurement.
Note
Charge the rechargeable NiMH batteries to capacity before using
them for the first time
