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
Battery status and faults are also indicated on the Dot display and the
Physiological Display dialog window.
If the accumulator is not in the charging station, the green LEDs flash
regularly and simultaneously.
Fully or nearly fully (2/3) charged accumulator
1/3 to 2/3 fully charged accumulator
Nearly discharged accumulator; 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
A second set of sensors with charging station may be useful in

hospitals or radiology facilities because one PPU and PERU can be
permanently ready for operation, while a second PPU and PERU
are being charged.
The physiological signals are shown on the Dot display.
