The equipment is expected to be used in an electromagnetic environment where radio
frequency radiation disturbances are controlled. According to the maximum rated output
power of communication equipment, the purchaser or user can prevent electromagnetic
interference by maintaining the minimum distance between portable and mobile radio
frequency communication equipment (transmitter) and the equipment as recommended
below.

For the maximum rated output power of the transmitter not listed in the above table, the
recommended isolation distance d, in meters (m), can be determined by the formula in the
corresponding transmitter frequency column, where P is the emission provided by the
transmitter manufacturer. The maximum rated output frequency of the machine, in watts (W).
Note 1: At 80 MHz and 800 MHz frequency points, the higher frequency band formula is used.
Note 2: These guidelines may not be suitable for all situations. Electromagnetic propagation
is affected by absorption and reflection from buildings, objects and human bodies.
16. Anti-Static Precautions
When using this equipment, users should not touch the pins of connectors
marked with electrostatic discharge warning symbols and should not connect to
these connectors unless electrostatic discharge precautions are used.
Users should note:
1.
Unless the following appropriate precautions have been taken, do not touch
the accessible connector contacts marked with electrostatic discharge
warning symbols with your hands or hand tools. Preventive measures
include,
a)
Methods to prevent static charge accumulation (such as air conditioning,
humidification, conductive floor coatings, non-synthetic clothing);
b)
Make the human body discharge to the frame of the equipment or
system or to the ground or to large metal objects.
c)
Use the wrist strap method connects the body to the device or system
or ground.
2.
All staff who may touch the connector marked with the electrostatic
discharge warning symbol should receive this explanation and training. This
also includes clinical/biomedical engineering and healthcare personnel.
3.
Electrostatic discharge training should include an introduction to the physics
of electrostatic charge and the voltage levels that may be generated in
normal practice, as well as the damage of electronic components if an
operator with static electricity touches electronic components. Furthermore,
it should explain the methods to prevent the accumulation of static charge,
and how and why the human body is discharged to the ground or the frame
of the equipment or system, or to connect the body to the equipment or
system or to the ground through a wrist strap before working.
