In the case of green and red flashing, the power supply
cannot be reset with the OFF/ON operation at the mains
power supply, remote control, and wall outlet.
For the alarm reset, keep pressing the input changeover key
of the main unit and move the mains power supply to the
"ON" position at the main unit. While doing so, it is
necessary to keep pressing the input changeover key of the
main unit for more than two seconds.In the case of green
and red flashing, the power supply cannot be reset with the
OFF/ON operation at the mains power supply, remote
control, and wall outlet.
