Precautions
Power Supplies
When turning the power ON and OFF, input signal reception is pos-
sible, unstable, or impossible as shown in the diagram below.

OFF
Apply the power supply voltage through a relay or switch in such a
way that the voltage reaches a fixed value immediately.
Turn the power ON and OFF with relay with a rated capacity of 10 A
minimum to prevent contact deterioration due to inrush current
caused by turning the power ON and OFF.
