Caution
“Pulling the Plug”
This “method” should be avoided under all circumstances. It can
damage the hardware and corrupt files. This “method” is
especially critical if the RF port is still connected to a grounded
system under test. Residual discharges may flow via RF Ground /
Shield. With the main connector no longer plugged in, ground
connection is also disrupted.
