TABLE OF CONTENTS NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro-

static break-down because of the potential difference generated by

the charged electrostatic load, etc. on clothing and the human body.

During repair, pay attention to electrostatic break-down and also

use the procedure in the printed matter which is included in the

repair parts.

The ﬂexible board is easily damaged and should be handled with

care.

NOTES ON LASER DIODE EMISSION CHECK

Never look into the laser diode emission from right above when

checking it for adjustment. It is feared that you will lose your sight.

If the optical pick-up block is defective, please replace the whole

optical pick-up block.

Never turn the semi-ﬁxed resistor located at the side of optical

pick-up block.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead-

free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 °C higher

than ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350 °C.

Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

• Strong viscosity

Unleaded solder is more viscous (sticky, less prone to ﬂow)

than ordinary solder so use caution not to let solder bridges

occur such as on IC pins, etc.

• Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

COMMANDER

CLEANING THE CONNECTORS

CANCELING THE DEMO MODE

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 re or

explosion.

Notes on the lithium battery

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.

+ side up

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 (page 6) and clean the connectors with

a cotton swab. Do not apply too much force.

Otherwise, the connectors may be damaged.

Notes

For safety, turn o the ignition before cleaning the

connectors, and remove the key from the ignition

switch.

Never touch the connectors directly with your ngers

or with any metal device.

You can cancel the demonstration display which

appears while this unit is turned o.

* 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.

1Activate the NFC function on the

smartphone.

For details, refer to the operating instructions

supplied with the smartphone.

2Touch the N-Mark part of the unit with

the N-Mark part of the smartphone.

Make sure that lights up on the display of the

unit.

To disconnect by One touch

Touch the N-Mark part of the unit with the N-Mark

part of the smartphone again.

Notes

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.

AFFIXING OF LABEL (SERIAL NUMBER)

When the front panel (SV) (assy) is replaced, it is necessary to afﬁx the label (serial number).

2 labels (serial number) are included with a new front panel (SV) (assy). Afﬁx 1 label to the rear side of the front panel (SV) (assy). Afﬁx

the other one to the bottom side of main unit.

Be sure to perform this procedure, as Bluetooth will not operate correctly if the serial number of the front panel (SV) (assy) and main unit

do not match.

Also, since the serial number has changed, print page 13 and hand the tear-off with the product to the customer when returning the product

after repairs are complete.
