3.4 Power Sources / Connector Sockets
The LSU is delivered with an AC Power Cord for connection to AC
mains and a DC Power Cord for connection to DC mains.
The device can be operated from the internal battery, and can be
operated or charged from the following external Power Sources:
- AC mains when used with the AC Power Cord: (Max. length 1.5 m.)
100-240 VAC (50/60 Hz).
- DC mains when used with the DC Power Cord: (Max. length 1.5 m.)
12-28 VDC.
A Wall Bracket to hold the LSU during operation and charging is
available separately (see section 8).
External power connection will cause the External Power Indicator
to be lit.
3.5 Automatic Power-save Function
The LSU has an Automatic Power-save Function that switches OFF
the pump motor. While in this mode, the Power ON Indicator will
flash slowly (approx. once per second).
This function will be activated when the Operating Knob is set to 200,
350 or 500+ mmHg and the actual vacuum level has been
continuously higher than 120 mmHg for 2 minutes.
To exit the Power-save Mode and revert to normal operation, set the
Operating Knob to any position and then go back to required setting.
