NOTE  OF  REPLACING  THE  KEY  BOARD
When the KEY board is defective, replace the FRONT PANEL 
(SV) (ASSY) (Ref. No. FP1).

NOTE  OF  REPLACING  THE  IC804,  IC1002  AND  IC1009  
ON  THE  MAIN  BOARD
IC804, IC1002 and IC1009 on the MAIN board cannot replace 
with single. When these parts are damaged, replace the complete 
mounted board.

When the battery becomes weak, the range of the 
remote commander becomes shorter. Replace the 
battery with a new CR2025 lithium battery. Use of 
any other battery may present a risk of fire or 
explosion.

Keep the lithium battery out of the reach of children. 
Should the battery be swallowed, immediately 
consult a doctor.
Wipe the battery with a dry cloth to assure a good 
contact.
Be sure to observe the correct polarity when installing 
the battery.
Do not hold the battery with metallic tweezers, 
otherwise a short-circuit may occur.

The unit may not function properly if the 
connectors between the unit and the front panel 
are not clean. In order to prevent this, detach the 
front panel and clean the connectors with 
a cotton swab. Do not apply too much force. 
Otherwise, the connectors may be damaged.

For safety, turn off the ignition before cleaning the 
connectors, and remove the key from the ignition 
switch.
Never touch the connectors directly with your fingers 
or with any metal device.

You can cancel the demonstration display which 
appears while this unit is turned off.

The setting is complete.

The display returns to normal reception/play 
mode.

connected with the smartphone automatically.

* NFC (Near Field Communication) is a technology 

enabling short-range wireless communication 
between various devices, such as mobile phones and 
IC tags. Thanks to the NFC function, data 
communication can be achieved easily just by 
touching the relevant symbol or designated location 
on NFC compatible devices.

For a smartphone with Android OS 4.0 or lower 
installed, downloading the app “NFC Easy Connect” 
available at Google Play™ is required. The app may 
not be downloadable in some countries/regions.

For details, refer to the operating instructions 
supplied with the smartphone.

Make sure that 

 lights up on the display of the 

unit.

Touch the N-Mark part of the unit with the N-Mark 
part of the smartphone again.

When making the connection, handle the 
smartphone carefully to prevent scratches.
One touch connection is not possible when the unit is 
already connected to another NFC compatible device. 
In this case, disconnect the other device, and make 
connection with the smartphone again.
