Advanced Operation
Initialization of the Microprocessor
• In very rare instances, the AVR-4806CI internal
microprocessor might lock up, or otherwise cause mis-
operation. This might be caused due to an AC line surge or
line spike noise, or by static electric discharge on or nearby
the unit, or to connected components. If the condition
cannot be corrected by powering off the unit, including
disconnection of the power supply cord for a period of ten
minutes and subsequent re-connection, then the unit may
have to be re-initialized. Doing so will restore the
microprocessor to its original out-of-the-box state, with all
custom memories and settings erased, and the original
factory default settings restored. Only use this procedure if
you are sure that the microprocessor requires re-
initialization.
1
Switch off the unit using the main unit’s
POWER switch.
2
Hold the following PURE DIRECT button and
DIRECT/STEREO button, and turn the main
unit’s
POWER switch on.
3
Check that the entire display is flashing with
an interval of about 1 second, and release your
fingers from the 2 buttons.
• The microprocessor will be initialized.
• If step 3 does not work, start over from step 1.
•If the microprocessor has been reset, all the settings are
reset to the default values (the values set upon shipment
from the factory).

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
resetting 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 from when the main unit’s power switch is off and
with the power supply cord disconnected.
