●Starting DIAG
For DSP-AX1:
Press the “POWER”(STANDBY/ON) key of the main unit while pressing the “SET MENU+”key and the “NEXT”key
located in the sealing panel of the main unit, and DIAG will be activated.
For RX-V1:
Press the “POWER”(STANDBY/ON) key of the main unit while pressing the “PROGRAM w”key and the “EFFECT”
key located in the sealing panel of the main unit, and DIAG will be activated.
●Starting DIAG in the protection cancel mode
If the power supply, amplifier protection function is activated and hinders the trouble diagnosis, cancel the protec-
tion function as described below, and it will be possible to enter the DIAG mode. (The protection function other than
the excess current detect function will be cancelled.)
For DSP-AX1:
Press the “POWER”(STANDBY/ON) key while pressing the “SET MENU+”key and the “NEXT”key. At this time,
keep pressing the “SET MENU+”key and the “NEXT”for 3 seconds or longer.
For RX-V1:
Press the “POWER”(STANDBY/ON) key while pressing the “PROGRAM w”key and the “EFFECT”key. At this
time, keep pressing the “PROGRAM w”key and the “EFFECT”key for 3 seconds or longer.
In this mode, “V”in the FL display of the main unit flashes.
CAUTION!
Using this product with the protection function cancelled may cause damage to itself. Use special care for this point
when using this mode.
●Canceling DIAG
Turn off the power by pressing the “POWER”(STANDBY/ON) key of the main unit or the “STANDBY”key of the
remote control unit.
CAUTION: When canceling this function, check that DIAG menu No.10 PRESET (memory initialization inhibited/
reserved) has been set. (To keep the user memory, be sure to select “INHIBIT”(initialization inhibited) from the
No.10 PRESET menu before canceling the DIAG function.)

the voltage value recorded last are displayed.
Checksum (4 figures consisting of alphabets and numbers)
The checksum is obtained by adding 4M bits per 1 octo of the entire program code and expressing the result as a
4-figure hexadecimal data. (0xff is added for the area where no code has been entered and for the area other than
ROM code.)

In the case where the protection function works after DIAG has been started and the power is turned off ;
When the protection function (*2) works, the history of the protection function appears on display and the power
turns off. Repair the faulty parts according to the displayed history.
(*2) When an excess current or any other faulty condition is found with the power source, DC, etc., the protection
function forces the power to turn off.
I PROTECTION display
(When the power is turned on without an abnormality corrected, the protec-
tion function works the moment the power relay is turned on to shut off the
power supply.)
Cause: There is an abnormal current flow to the power amplifier.
Supplementary information: If I PROTECTION function has worked after
SP relay ON, a warning message “CHECK SP WIRES”appears the next
time the power is turned on. This indicates that some trouble exists after
the SP terminal, such as a short-circuit of the speaker cable.
PS PRT display
(When the power is turned on without an abnormality corrected, the
protection function works about 1 second later to shut off the power supply.
Display may not be provided, if there is an abnormality with the power
supply for the display.)
Cause: There is an abnormality in the power supply section (voltage).
Supplementary information: As the power from following sources is
detected, it is possible to determine where an abnormality exists.
Transformer secondary winding
VI X 2(CB704), YE x 2(CB482)
U, C only : GY x 2(CB481)
Stabilizing power source
±12, ±5V, +5D1, +5D2, +3.3, VP
DC PRT display
(When the power is turned on without an abnormality corrected, the protec-
tion function works about 3 seconds later to shut off the power supply.)
Cause: A DC output from the power amplifier is detected in the bad
channel.
TMP PRT display
(When the power is turned on without an abnormality corrected, the protec-
tion function works about 3 seconds later to shut off the power supply.)
Cause: The temperature of the heat sinks in the power amplifier is
detected. When the temperature rises and an abnormality is detected, the
power turns off.

●History of protection function
When the protection function has worked, its history is stored in memory with a backup. Even when no abnormality is noted while
the unit is being serviced, an abnormality which has occurred previously can be defined as long as the backup data has been
stored.
The protection history is cleared when DIAG is canceled by selecting “RESERVED”(memory initialization) from the setting items
of the DIAG menu No.10 PRESET or when the backup data is erased.
Besides the above possible causes, the cause may exist in the disconnected connector or around CPU.
PS PRT, DC PRT and TMP PRT displays include the abnormal A/D value in % (voltage value obtained by consid-
ering 5V as 100%). Concerning this value, refer to DIAG menu No.11 FAN/AD described on page 28.
