■ 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.

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.

• 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.
