LAST FUNCTION MEMORY
• This unit is equipped with a last function memory which stores the input and output setting conditions as they were immediately before the
power is switched off.
This function eliminates the need to perform complicated resettings when the power is switched on.
• The unit is also equipped with a back-up memory. This function provides approximately one week of memory storage when the main unit’s
power switch is off and with the power cord disconnected.
14
INITIALIZATION OF THE MICROPROCESSOR
When the indication of the display is not normal or when the operation of the unit does not shows the reasonable result, the initialization of the
microprocessor is required by the following procedure.
1
Switch off the unit and remove the AC cord from the AVR-
4800 rear panel. Wait for 15 seconds.
2
Press and hold the 6.1/7.1 SURROUND buttons and DIRECT
buttons, and at the same time, plug in the AC cord.
3
Check that the entire display is flashing with an interval of
about 1 second, and release your fingers from the 2 buttons
and the microprocessor will be initialized.
NOTES:
• If step 3 does not work, start over from step 1.
• If the microprocessor has been reset, all the button settings are
reset to the default values (the values set upon shipment from
the factory).
