TEST MODE
●How to enter the test mode
Press and hold the [1] and [3] keys and reset.
(While “– – – –” is being displayed, power can be ON for 30 minutes.)
●How to clear the test mode
Reset, momentary power down, Acc OFF, Power OFF, detach the panel.
●Test mode default condition
•Source is STANDBY.
•Display lights are all turned on.
•The volume is at 30 (-10dB).
•LOUD is OFF.
•CRSC is off regardless of the availability of switching function.
•SYSTEM Q is NATURAL (=FLAT).
•BEEP should always function when the key is pressed briefl y.
•AUX is ON.
●Speciication of the test mode for tuner sourse
The frequency of 98.3MHz is received when the [4] key is pressed in the TUNER FM mode
●Specification of FST soft mute adjustment mode
1.Receive the TUNER FM mode in the VOLUME 30 and LOUD OFF condition.
2.Press and hold the [ 
] key for 2 seconds to enter the FST soft mute adjustment mode.
3.In the adjustment mode, the following display is shown. Adjust the mute between 0 (18dBu) and F (36dBu) with the [FM] / [AM] keys.
(Display) SMD–x_ _ _ (Adjustment value, 0~F is displayed in “x”).
4.When the adjustment is “OK”, press and hold the [ 
] key for 2 seconds again to write the adjustment value in the E2PROM, and after the successful writing-in the “EP_WRITE” is displayed.
5.Press the [ 
] key briefl y to exit from the FST soft mute adjustment mode.
(The test mode continues.)
● Special display in tuner mode
Error is found in front-end, etc. if indications below are displayed while in tuner mode.

• “TNCON_NG” : Cannot communicate with the front-end.
●RDS/RBDS automatic measurement
Add the process to replace the visual inspection of PS display previously done in the production line.
When it is confi rmed that the PS data has been received and that the content of the PS is “RDS_TEST”, force to OFF the P-CON terminal. ( The symbol, “_” indicates the blank. )
→Make this as the process dedicated for the test mode. P-CON is recovered by Power OFF→ON.
●K3I forced switching
Every time when [6] key is pressed in tuner FM mode,
switched in the following order: AUTO→Forced WIDE
→Forced MIDDLE→Forced NARROW→AUTO. Default status is AUTO, and displayed as shown below.

DC OFFSET ERROR
●Purpose
Prevent customer’s vehicle speakers damages, burnouts, and smoking.
Avoid the connected speakers to be burned out, damaged, or to smoke when DC occurs between the audio power amp. + and - outputs.
●Processing after detection
•System status
•At the detection of DC error, error data is to be saved immediately (E2PROM error log save area).
•Display the error message on the display. The system shall maintain the current condition, including the operation. Shut down audio system power supply. Set Mute to ON.
•Although switching between Power OFF and ON (ACC, BU, and Key operation) is valid, switching from Off to ON shall be error until the µ-com is reset.
While power-on, even if the IC2VI DCErr output terminal logic recovered to normal level value, the error condition shall continue.
•Prohibit to save the backup/installer memory to E2PROM (nonvolatile memory).
•Controlling µ-com terminal
•Set Mute for all channels including for pre-out.
•Turn off power IC control system power supply. (Set AMPStandby function to valid)
•Set P-Con output to OFF (Logic by which external AMP unit is turned off).
The purpose is to shut down audio output. Basically, the logic sets the audio output system signal line when in Standby source.
•Key specification
•Other keys than eject and power keys are invalid.
•Display specification
•Display the “PROTECT” string and blink all characters at 1Hz.
Use the indication below with the highest priority (error message), and maintain the error message even when the source is changed.

● Cancel Condition
•Press the Reset terminal on the main body. Or set Backup to OFF (Unplug and plug back in the DC connector).
The history is maintained (E2PROM data is saved).
•If DC error is detected during the capacitor leak detection period, the clearing the error by the reset is limited to 4 times.
The startup is inhibited for the 5th time and later reset. ("PROTECT" display has to be blinked.)
● Note while in the test mode
•While in the test mode, even if DC leak is detected, it is not written into E2PROM.
When an error is detected, the display is enabled.
● Other
•Function for checking and clearing data in E2PROM by a given key shall be included. (Used at production dpt. and service center, etc.)
