1、P 11 D C : 5 1 P1. SYSTEM MONITOR This menu is used to display the A/D conversion value of the microprocessor which detects panel keys and protection functions by using the sub-menu. When “P1-7. KEY1/KEY2” sub-menu is selected, keys become non-operable due to detection of the values of all keys. How
2、ever, it is possible to advance to the next sub-menu by pressing the “SCENE RADIO” (forward) key or “SCENE CD” (reverse) key on the remote control. * Numeric values in the figure are given as reference only. P1-1. DC Power amplifier DC (DC voltage) output is detected. The voltage at 5 pin (DC_PRT) o
3、f IC89 is displayed. Normal value: 35 to 68 (Reference voltage: 3.3 V=255) * If DC becomes out of the normal value range, the protection function works to turn off the power. P1-2. PS1/PS2 Power supply voltage protection detection The voltage at 2 pin (PS1_PRT)/1 pin (PS2_PRT) of IC89 are displayed.

8、ed. When the A/D conversion value of the panel key becomes out of the specified range, normal operation will not be available. In that case, check the constant of voltage dividing resistor, solder condition, etc. Refer to table. * When “P1-7. KEY1/KEY2” menu is selected, keys become non-operable due
9、 to detection of the values of all keys. However, it is possible to advance to the next sub-menu by pressing the “SCENE RADIO” (forward) key or “SCENE CD” (reverse) key on the remote control.
