G Display when DIAG function is started First, “DIAG” appears on the FL display of the main unit, followed by the v

34、ersion of the microcomputer for 1 second (e.g., 1.223f), the checksum of the microcomputer for 2 seconds (e.g., 83B3) and finally the DIAG menu (e.g., 1: ALL).

36、d the power is turned off ; When the protection function (*2) activates, the protection function history appears on the display and the power turns off. Repair the faulty parts according to the displayed history. (*2) When any other faulty condition is found with the power source etc., the protectio

37、n function forces the power to turn off. PT PS display (When the power is turned on without this abnormality corrected, the protection function activates to shut off the power relay. Display may not light if there is an abnormality with the power supply for the display.) Cause: There is an abnormali

38、ty in the power supply section (voltage). Supplementary information: As the power from the following sources is detected, it is possible to determine where an abnormality exists. Stabilizing power source 15A, +9V, +5A, +5D SW, -VP +12V(Tuner), Vcc(for power IC) Besides the above possible causes, the

39、 cause may be disconnection of the connector or around the CPU. G Protection history When the protection function has activated, its history is stored in memory with a memory backup. Even when no abnormality is noted while the unit is being serviced, an abnormality which has occurred previously can

40、be defined as long as the backup data has been stored. The protection history should always be cleared before returning the unit from service. The protection history is cleared when DIAG is canceled by selecting “MEMORY” (memory initialization) from the setting items of the DIAG menu No.7 INT or whe

41、n the backup data is erased. RP-U200 RP-U200 7 G Canceling DIAG There are two methods to cancel the DIAG function. 1) Press the “POWER” (STANDBY) key of the main unit or the “POWER” (STANDBY) key of the remote controller to enter the stand-by state. 2) Selecting the DIAG menu item 0. EXIT, cancel th

42、e DIAG function. Then the self-diagnosis process ends and the normal operation is restored. CAUTION: Prior to cancellation of the DIAG function, be sure to execute setting of DIAG menu 7. INIT (reserve / reserve cancel of memory initialization). (To keep the user memory, execute “CANCEL” (cancellati

43、on of resetting reservation) of 7. INIT setting before canceling the DIAG function.) G Operation procedure of DIAG menu and SUB-MENU 1) Use the UP w (forward) / DOWN q (reverse) keys to select a main menu item. 2) For main menu items 1. ALL and 2. DEV neither of which has sub menu, the menu item is

44、executed when the DSP key is pressed. 3) For main menu items which have sub menu, the sub menu appears when the DSP key is pressed. 4) Use the UP w (forward) / DOWN q (reverse) keys to select a sub-menu item. 5) The sub-menu item is executed when the DSP key is pressed. 6) To return from the sub-men

45、u to the main menu, have “RETURN” displayed by using the UP w (forward) / DOWN q (reverse) keys and press the DSP key. 7) To return to the DIAG initial setting (1.ALL) during DIAG operation, press the MUTE key of remote control unit except for the special case (*3). (*3) : It is not possible to retu

46、rn to 1.ALL during execution of the AD test. Main unit UP w (forward) DOWN q (reverse) DSP MUTE Remote control key VOLUME UP w (forward) VOLUME DOWN q (reverse) ON/OFF Return the menu to the 1.
