The > mark found on some component parts indicates

the importance of the safety factor of the part.

Therefore, when replacing, be sure to use parts of

identical designation.

Symbol indicates a resistor.

No differentiation is made between chip resistors and

discrete resistors.

NOTE :

Symbol indicates a capacitor.

No differentiation is made between chip capacitors and

discrete capacitors.

mode

All-element lighting mode SW check mode

Service check mode

The physical addresses for all devices connected to the AVC-LAN (including this product) are

displayed. The current and past product conditions are checked by performing the system check

and collecting the diagnosis memory data. Each address check result is displayed as follows: "OK",

"Not connected", "Check", "Replace", "Old Version" or "No response".

Details display mode

This mode is available only when the service check result is "Check", "Replace" or "Old

Version". For each physical address, the following information is displayed:

- Logical address for the device where some failure occurs and the diagnosis codes

(indicating details of the failure), which were obtained through system check

- In addition to the above data, sub-code (indicating the device with failure), connecting

confirmation no. (time stamp), and frequency of occurrence, which were obtained from

diagnosis memory data

Diagnosis memory

clearance

< From the service check mode >

The diagnosis memory data

(codes) for all devices connected

are cleared.

< From the details display mode >

The diagnosis memory data for

devices selected is cleared.

After memory clearance is

completed, the mode is

automatically shifted to the

service check mode.

Note *1: To enter the diagnosis IN mode,

use the buttons on the head unit.

(1) Diagnosis IN While pressing the CH1 and CH6

With three times of beep sound, the mode buttons simultaneously, press the

change operation completes. DISC button three times.

(2) Diagnosis OUT Keep the DISC button pressed for

After system check completes, the check results for the

devices connected to the AVC-LAN are displayed in

turn in order of physical address number as follows:

"Physical address"

...

The smallest physical address number is displayed

first, whose check result will follow it.

Ex. P190

Physical address number

(radio cassette)

The physical address is displayed.

"Check result"

...The check result is displayed.

Ex. good Normal (OK)

ECHn Replace

"Physical address"

...

The next physical address number is displayed.

"Connecting confirmation no. (current)"

...The AVC-LAN time stamp is displayed.

Ex. no01

The connecting confirmation

number is displayed.

The current connecting confirmation

number (expressed in the hexadecimal

number system by using 00 to FF)

The number increases by one each time one minute

passes. When 256 minutes pass, the indication

returns to 00.

Service check mode

Details display

mode

Details display mode (only in case of "Replace", "Check", or "Old Version")

This mode is available only when the service check result is "Replace", "Check" or "Old Version".

To select this mode, press the CH2 key.

"Physical address (for selected devices)"

The physical address number is displayed, whose check result details will follow it.

Ex. P360

Physical address number (CD-CH)

"Diagnosis data source"

The detailed items depend on the data source.

Ex. SyS The data was obtained from

system check.

"Logical address"

The logical address number for the device

with failure is displayed.

Ex. 1L_63

Logical address number (CD-CH)

The logical address is displayed.

Serial number

"Diagnosis code"

The diagnosis code indicates what problem occurs.

Ex. 1d_45

Diagnosis code (abnormal EJECT)

The diagnosis code is displayed.

If there are two or more diagnosis codes, the diagnosis

data display will continue.

Ex. COdE

The data was obtained from diagnosis memory data.

"Logical address"...The same as that for the SyS data

"Diagnosis code"...The same as that for the SyS data

"Sub code"...This code indicates the device with failure.

Ex. 1P_190

The sub code is displayed.

"Connecting confirmation number (when some failure

occurs)"... AVC-LAN time stamp

Ex. no01

The connecting confirmation number (expressed in

the hexadecimal number system by using 00 to FF)

The connecting confirmation number is displayed.

"Frequency of occurrence"

...The frequency of failures occurred

Ex. 1c_15

The frequency of occurrence expressed in the

decimal number system.

The frequency of occurrence is displayed.

Automatic Tuning

Broadcast stations above a certain signal

strength can be tuned into automatically.

To cancel, press the button again.

Press the button down either on the “ ” side

or the “ ” side. The automatic tuning will start,

and the radio will find and tune into the sta-

tion.

Manual Tuning

This is useful to tune into a station with a weak

signal that cannot be found with the automatic

tuning.

Turn the knob clockwise or counterclockwise

until you find the frequency you want.

Preset Memory

This function is used to memorize radio sta-

tions. To memorize a station:

Choose one button and press it down for

about 1.7 seconds until you hear a beep.

To select a memorized station:

Having memorized a station, you can press

the same button again and within 1.7 sec-

onds the radio will tune into that memorized

station.

AM Tuning Step

The tuning step employed in the radio’s AM

band can be switched between 9 kHz and 10

kHz per step. Reset the tuning step from 9

kHz (the factory preset step) to 10 kHz when

you want to receive a 10 kHz step broadcast

station (530 – 1,710 kHz) in Vietnam.

Initial setting: 9 kHz step (531 – 1,602 kHz)

New setting: 10 kHz step (530 – 1,710 kHz)

1. Push the power button to turn the unit

off.

2. Simultaneously press buttons 2 and 5 of

more than 1.7 seconds. The current AM

tuning step is indicated in the display.

3. Press the “

” or “ ” side of to select

the tuning step.

4. Simultaneously press buttons 2 and 5 of

.

A beep sounds to inform you that the tun-

ing step has changed and preset memory

will be cleared.

Preset Scan

The radio will automatically tune in to all of

your preset stations which are of a certain

signal strength one by one for about 10 sec-

onds each.

Keep the button pressed for more than 1.7

seconds, until you hear a beep. T o cancel the

preset scan, press the button again.

• If you choose Preset Scan on the FM

waveband, it will be automatically carried

out on both FM1 and FM2.

• Preset Scan is for reception of strong broad-

cast station transmissions only. You can-

not use it for reception of weak broadcast

station transmissions.

Scan

The radio will automatically tune in to stations

which are of a certain signal strength in turn

for about 10 seconds each.

Press the button quickly (for less than 1.7

seconds). To cancel the scan, press the but-

ton again.

Mode

This selects the volume and tone adjustment

modes. Press the knob to change the mode.

After selecting the mode, adjust using this

knob.

BAS (Bass)

TRE (Treble)

FAD (Fader)

BAL (Balance)

Adjustment

Carry out adjustment of the mode selected

with this knob. Adjust by turning the knob

clockwise or counterclockwise.
