11. FAN/AD
The sub-menu of this menu displays the A/D conversion value of the main CPU (function circuit board IC27) which
detects the keys and protection functions of the main unit in %. (100% represents 5V.)
It also displays the history of the fan being driven. When in KY0/KY1 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 input selector of the main unit will
cancel this function and sets to the next sub-menu. Clicking there more than once would change the input. If this
has occurred, restore the input being tested. The signal processing state remains the same as that before execut-
ing this menu.

FAN HISTORY (History of fan being driven)
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.

The above figures are examples for

MTR/THM/PRD/PRV [Remote control code: 7A—56 (EFFECT)]
(Detection of the tuner sensitivity, temperature of the heat sink and protection
function)
MTR: Signal sensitivity of the tuner (RX-V1 only)
THM: Detection of the temperature of the heat sink (Normal value: 6~40)
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)
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)
When the value is out of the normal value range, the protection function
works to turn off the power.

• When the standard value is deviated by ±4%, KEY A/D fails to function prop-
erly, In this case, check the constant of the partial pressure resistor, soldering
condition, etc.
