Recalibrating Batteries
Over time, the V*Home batteries (the removable, rechargeable batteries and/or the internal battery) may require
recalibration to report their charge status correctly in the V*Home status bar.
If the three relative state of charge icons in the V*Home status bar do not report that the batteries are fully charged even
after V*Home has been plugged in for 24 hours or more, disconnect V*Home from the patient and recalibrate the batteries
by following these steps:
1 Plug V*Home into external power and charge the
batteries until the charge status LED on the front of
the device turns green.
2 Unplug V*Home from external power to begin
draining the batteries.
3 Discharge all three batteries completely. V*Home
will alarm and shut down when no battery power
remains.
4 Allow V*Home to sit off and disconnected from
external power for at least 5 hours.
5 Plug V*Home into external power and charge the
batteries uninterrupted until the charge status LED
on the front of the device turns green for at least 30
minutes.
NOTE: In addition to the relative state of charge status
shown in the status bar, V*Home reports the battery absolute
state of charge. These values naturally decrease over
time and are shown on the My VOCSN screen. When the
absolute state of charge of a battery is <50% after charging
for 24 hours, the battery should be replaced.
