10. FAN/AD
The sub-menu of this menu displays the A/D conversion value of the CPU (function circuit board IC526) which
detects the keys and protection functions of the main unit in %. (reference voltage 5V: 100%)
It also displays the history of the fan being driven. When in KY0/KY1/RECOUT page, it is not possible to operate the
keys of the main unit because the values of all keys are detected. But one click on the VOLUME of the main unit will
cancel this function and sets to the next sub-menu. If this has occurred, restore the DIAG menu being used for
testing. The signal processing state remains the same as that before executing this menu.

FAN HISTORY (History of fan being driven) [Remote control code: – – – – ]
The voltage value detected from the temperature detect circuit is read by the A/D function of
the microprocessor as a data. Based on that temperature data, the fan driving speed is
controlled in 3 stages. How the fan has been driven is displayed as the history.

THM/PRD/PRV [Remote control code: 7A—0B (CD SKIP –)]
(Detection of the temperature of the heat sink and protection function)
THM: Detection of the temperature of the heat sink (Normal value: 6~40) 0.3V~ 2.0V (reference voltage)
At 5% or less, the protection function works to turn off the power. At more than 40%,
possibility is that there is an error in the temperature detection system.
PRD: Protection value for DC detection (Normal value: 1~13) 0.05V~ 0.65V (reference voltage)
When the value is out of the normal value range, the protection function works to turn
off the power.
PRV: Protection value for power voltage (Normal value: 5~15) 0.25V~ 0.75V (reference voltage)
When the value is out of the normal value range, the protection function works to turn
off the power.
