No Power 1. Examine the power cord to ensure that it is connected to both
the ~ac mains connector and a wall outlet.
2. Make sure the Nº 320S is powered on with the front panel
power button.

standby LED blinks red to indicate that the Nº 320S is in
standby and lights red to indicate that the Nº 320S is not in
standby.
4. Make sure display intensity has not been set to OFF (0%),
deactivating the front panel display.

supplied to the wall outlet to which the Nº 320S is connected.

Operation transmitter and the front panel display IR receiver.
2. Make sure the rear panel ir input connector is not being used.

(5m) of the front panel display IR receiver. If the Nº 320S is
placed inside a glass cabinet, tinted glass will reduce the
remote control range.

front panel display IR receiver at a reasonable angle.
5. Make sure the front panel display IR receiver is not exposed
to strong sunlight, halogen light, or fluorescent light. This can
cause IR reception to become unreliable.
