Connecting the AC power cord (mains lead)

(the mains).
“– –:– –” appears on the display.
2. Press the STANDBY/ON button.
Notes
• If the AC power cord (mains lead) is connected to the AC outlet
of another component, that component's AC power cord (mains
lead) must be connected to the wall outlet (the mains) to supply
power to the unit. If the component has a power switch, it must be
set to On.
• If you do not use the unit for a long time, remove the power cord
of the CR-305X from the AC outlet.
• The unit may cause a power surge on your home circuit when you
turn it on. If this interferes with any other devices connected to
the same circuit, plug this unit into another outlet on a separate
circuit.
