when a connected electric device is switched on.
Section D.2 at the end of these instructions offers
information concerning electrical systems employing
different power plug designs.
When connecting electrically operated
equipment to the dust extractor, please ob-
serve the operating instructions and safety
information provided with the equipment.
The unit power outlet is to be used only for
connecting electric, dust-generating de-
vices to be operated in conjunction with the
dust extractor.
The unit power outlet is live once the Silent
TS has been connected to the power supply
– even when the Silent TS is switched off.
This allows connected devices to be oper-
ated without extraction for brief periods.
Power consumption of all devices con-
nected to the unit power outlet may not
exceed the rated value printed next to the
unit power outlet.

The factory set parameter for the start-up
threshold enables the Silent TS to react cor-
rectly for most electrical dental equiment.
Should this not be the case for a particu-
lar piece of equipment (eg. a handpiece),
then the start-up threshold can be adjusted
accordingly.
To change the activation threshold:
1. Switch Silent TS on.
2. Press and hold for 3 sec.;

least annually, for damage or signs of
aging. Immediately replace damaged power
cords.
