2 Power supply and battery operation
Thopaz
+
can be operated from the mains power supply 077.0148, from the docking
station 079.0037 or with the integrated lithium-ion battery. Before using the docking
station, read first the docking station instructions 200.1554. The battery is charged
during mains operation. The battery duration is dependent on the run-time of Thopaz
+
.
This is influenced by the extent of parenchymal leakage and the set pressure. Thopaz
+
does not run continuously but only switches on when the actual and nominal values differ.
During continuous operation, Medela guarantees a minimum run-time of 4 hours in battery
operation after the device has been fully charged. In practical operation the real battery run
time results in >10 hours.
If Thopaz
+
is not used very often, the battery must be charged approximately every 6 months
to ensure optimum functioning.
Press simultaneously to acknowledge an acoustic alarm and
follow instructions on the display (see chapter 12 –
Troubleshooting and alarms).
Battery low
Approximately 30 minutes before the battery is fully empty an acoustic signal sounds and the
battery symbol [
] starts to blink. The acoustic signal can be muted but the battery symbol
continues to blink until the battery is empty. The set pressure is maintained but the battery
should be recharged as soon as possible.
Charge battery
Plug the Thopaz
+
power supply into a wall outlet and open the
small protection cover to access the DC socket. Plug the coaxi-
al power supply into the DC socket. Moving bars on the battery
display will indicate charging is occurring [
].
Backup battery
If an internal defect occurs (broken cable, battery defective) Thopaz
+
turns off and the
acoustic warning is sounded for at least 3 minutes (powered by a backup battery).
Under these conditions Thopaz
+
functions as a one way valve. Replace Thopaz
+
immediately.
