specification.
It is not possible to write if any other cable is used. If
installation has failed due to the use of any other cable
by mistake, the unit will not operate, e.g., the power to
the amplifier will not turn on. If such is the case,
reconnect using the cross cable of the above
specification with disconnecting the power cord of the
amplifier from the outlet and execute writing again.
• Never disconnect the power cord to the main unit until
installation is completed. When the power cord is
disconnected by mistake during the installation
process, perform the procedure all over again.
