Battery low
It is recommended to charge batteries before each test. When the batteries are low the
warning message is prompted on the PU by two beeps for an half charged battery and
three beeps for a complete discharged battery.
As soon as the message appears, you must change batteries immediately since the
system has only few minutes of endurance still available. The system allows to change
the battery during testing as well.
During the test, it is possible to monitor the battery status in real time by selecting
Information
from
View
menu.
Portable Unit
The PU can be supplied either by the Charger Unit or by rechargeable batteries. It is
recommended during Warm-up to supply it exclusively by the Charger Unit time in
order to save the battery used normally during the test.
The control panel of the Portable Unit is mainly composed by a keyboard, and 4 plugs
for power supply, turbine, antenna, heart frequency and sampling tube connections. The
following illustrations show in detail the control panel.
