Control LEDs (PMU version 2)
3 Green LEDs flash
2 Green LEDs flash
1 Green LED flashes
Red LED flashes (as regular as
the green LEDs)
Red LED is off
Red LED flashes rapidly
PMU display
92
The transmitter unit includes three green LEDs for signaling the
battery status and one red LED as fault indicator (for example,
insufficient skin contact of the ECG electrodes).
(1) 3 Green LEDs (battery status)
(2) 1 Red LED (fault)
(3) Transmitter unit
If the battery is not in the charging station, the green LEDs flash
regularly and simultaneously.
If only one green LED flashes, you should charge the battery for the
next patient.
Fully or nearly fully (2/3) charged battery
1/3 to 2/3 fully charged battery
Nearly discharged battery; remaining operating duration is 1 hour
Transmit function deactivated, unit is positioned outside the static mag-
netic field; no electrode/application fault detected
Transmit function activated; unit is positioned on the patient table in
the static magnetic field; no electrode/application fault detected
PERU: electrode fault - one or more ECG electrodes are not applied cor-
rectly or fell off
PPU: application fault - pulse sensor is not applied correctly at the finger
The PMU display gives you a graphical view of the patient's
physiological signals.
