Operating principle

A Medical Panel PC has four main components: the
arithmetic logic unit (ALU), the control unit, the memory,
and the input and output devices (collectively termed I/O).
These parts are interconnected by buses, often made of
groups of wires.

The control unit, ALU, and registers are collectively known as
a central processing unit (CPU).

Inside each of these parts are thousands to trillions of small
electrical circuits which can be turned off or on by means of
an electronic switch. Each circuit represents a bit (binary
digit) of information so that when the circuit is on it
represents a "1", and when off it represents a "0" (in positive
logic representation). The circuits are arranged in logic gates
so that one or more of the circuits may control the state of
one or more of the other circuits.
Cleaning the unit
1. Remember to turn off the power source and to unplug the
cord from the outlet before cleaning the unit.
2. Carefully dismount the unit or bring the unit down from
suspension to clean.
3. Please use a dry soft cloth to clean the unit.
4. Take a dry cloth and wipe the unit dry. Remember to avoid
having liquids seep into the internal components and areas
of the medical panel PC unit.
