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 is always activated by brieﬂ y pressing a button.

• AUX is ON (Internal AUX supporting model).

• DISPLAY TYPE is TYPE C.

• TUNER source display shall be as shown below:

For European models

Upper row=PS/Frequency, Middle row=Spectrum

analyzer/Clock, Lower row=Date

For models of destination “K” and “M”

Upper row=SNPS, Middle row=Spectrum analyzer/

Clock, Lower row=Date

• CD/USB source display shall be as shown below:

For all models

Upper row=P-TIME, Middle row=Spectrum analyzer/

Clock, Lower row=Date

• SOURCE SELECT shall be 2.

Speciﬁ cation of the test mode for tuner source

●

The frequency of 98.3MHz is received when the [4] key is

pressed in the TUNER FM mode..

(*1) Only in the test mode, [1] key, [2] key, [3] key, [4] key, [5]

key and [6] key shall be displayed on the multi-function

key.

1. Press the [FNC] key briefly to make the multi-function

display.

2. Rotate the control knob on the right side and use

the [ ]/[ ] keys to display the target key in the center.

3. Press the [ ] key brieﬂ y to ﬁ nalize the display.

(*2) Perform the same operations as above on the keys, [1],

[2], [3], [4], [5], and [6] of the remote controller.

Speciﬁ cation 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

and adjust the mute between 0 (18dBµ) and F (36dBµ)

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.)

RBDS auto 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.
