■ DISASSEMBLY PROCEDURES /

(Remove parts in the order as numbered.)

Cautions for disassembly and reassembly :

• Disconnect the power cable from the AC outlet.

• Spread soft cloth or the like and perform the work on it.

• Use full care as you may be injured by the front grille

or other part.

• All screws must be tightened securely to prevent air

leakage. Check the number of screws and their

positions when installing them.

• When installing parts, be careful not to have anything

such as cables caught between other parts.

• Make sure that all the removed driver (tweeter) parts

are reinstalled at specified positions.

When checking the P.C.B. :

• The Rear Unit removed from the unit does not work

because its grounding is loose. Be sure to connect the

ground of the Rear Unit to the chassis or GND with a

lead wire or the like. (Fig. A)

• Reconnect all cables (connectors) that have been

disconnected.

Be sure to use the extension cable for servicing for the

following section.

• Starting DIAG

To activate the DIAG function, press the “STANDBY/ON”

key of the remote controller while pressing the keys of the

main unit as shown below at the same time.

•

Starting DIAG in the protection cancel mode

If the protection function works and causes hindrance to

trouble diagnosis, cancel the protection function as

described below, and it will be possible to enter the DIAG

mode.

Press the “STANDBY/ON” key while simultaneously

pressing those two keys indicated in the figure above. At

this time, keep pressing those two keys for 3 seconds or

longer.

In this mode, the “SLEEP” segment of the FL display of the

main unit flashes to indicate that the mode is DIAG mode

with the protection functions disabled.

CAUTION!

Using this product with the protection function disabled

may cause damage to itself. Use special care for this

point when using this mode.

• Canceling DIAG

[1] Before canceling DIAG, execute setting for PRESET of

DIAG menu No.6 (Memory initialization inhibited or

Memory initialized).

* In order to keep the user memory stored, be sure to

select PRESET INHIBIT (Memory initialization

inhibited). Any protection history will remain in

memory.

[2] Turn off the power by pressing the “STANDBY/ON”

key of the main unit or the “STANDBY” key of the

remote controller.

Cause: The voltage in the power supply section is

abnormal.

Supplementary information: The abnormal voltage is

displayed in % based on 3.3V as 100%.

Turning on the power without correcting the abnormality

will cause the protection function to work 1 second later

and the power supply will be shut off.

• Display during menu operation

During the DIAG operation, the menu list described in the

section of the startup screen appears on the

superimposed screen and the function at work is indicated

on the FL indicator. The contents displayed during the

function operation are described in the later section on

details of functions.

• Operation procedure of DIAG menu and

SUB-MENU

There are 14 MENU items, each of which has some SUB-

MENU items.

DIAG menu selection

Select the DIAG menu by using the UP/DOWN

(Reverse) (Forward) key of the remote controller.

SUB-MENU selection

Select the DIAG sub-menu by using the LEFT/RIGHT

(Reverse) (Forward) keys.

• History of protection function

When the protection function has worked, its history is

stored in memory with a backup. Even if no abnormality

is noted while servicing the unit, an abnormality which

has occurred previously can be defined as long as the

backup data has been stored.

The history of the protection function is cleared when

DIAG is cancelled by selecting PRESET RESERVED

(Memory initialized) of DIAG menu No. 6 or when the

backup data is erased.

*To clear the protection history only, use the SUB menu
