Background
Integrated circuits (logical circuits and microprocessors) are used to
implement a wide variety of functions in dental/X-ray/CAD/CAM
systems.
The circuits must be miniaturized to a very high degree in order to
include as many functions as possible on these chips. This leads to
structure thicknesses as low as a few ten thousandths of a millimeter.
It is obvious that integrated circuits which are connected to plugs
leading outside of the unit via cables are sensitive to electrostatic
discharge.
Even voltages which are imperceptible to the user can cause
breakdown of the structures, thus leading to a discharge current which
melts the chip in the affected areas. Damage to individual integrated
circuits may cause malfunction or failure of the system.
To prevent this from happening, the ESD warning label next to the plug
warns of this hazard. ESD stands for ElectroStatic Discharge.
Connector pins or sockets bearing ESD warning labels must not be
touched or interconnected without ESD protective measures.
2.4
Connecting the unit
Perform connection by following the directions given in the present
operating instructions.
2.5
Connection of external equipment
If any devices not approved by Dentsply Sirona are connected, they
must comply with the applicable standards (see "Standards/ approvals/
certifications [→ 20]").
2.6
Ventilation slots
Under no circumstances may the ventilation slots on the rear of the unit
be covered, since otherwise the air circulation will be obstructed. This
can cause the unit to overheat.
Do not spray into the ventilation slots
Do not spray liquids such as disinfectants into the ventilation slots. This
may lead to malfunctions. Use wipe disinfection only in the vicinity of the
ventilation slots.
