Advanced Operation POWER DIRECT/STEREO PURE DIRECT 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. Initialization of the Microprocesssor • In very rare instances, the AVR-4806 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 reinitialized. 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). 86
