3. Precautions against strong electromagnetic waves
If strong electromagnetic waves are present near a personal computer during
communication, errors in data transmission or an unintended operation may
occur.
Under such conditions, check the electromagnetic status and take necessary
measures.
The following are general examples of factors that may interfere with the proper functioning of
the device and recommended solutions.
Cellular phone use
May cause undesired operation because cell phones emit electromagnetic waves.
In a room or building where the device is used, turn off cellular phones and other small
radio units.
High frequency noise from other devices via an electrical outlet
Detect the source of the noise and take measures to break the route, using a noise
suppressor.
Avoid using the noise generating device.
Use another electrical outlet.
Static electricity
Fully discharge the operator before use.
Humidify the room.
L
ightning strike
A nearby lightning strike may induce excessive voltage into the device. In the event of a
lightning strike:
Use an uninterruptible power supply to operate the device.
Using the device introduces noise into a television or radio.
Place the affected television or radio away from the device.
