SECTION 1

SERVICING NOTES

The SERVICING NOTES contains important information for servicing. Be sure to read this section before repairing the unit.

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.

REPLACING THE LITHIUM BATTERY OF THE REMOTE

COMMANDER

(DSX-A410BT: E, AR, IND, AUS/DSX-A415BT)

Under normal conditions, the battery will last

approximately 1 year. (The service life may be

shorter, depending on the conditions of use.)

When the battery becomes weak, the range of the

remote commander becomes shorter.

CAUTION

Danger of explosion if battery is incorrectly

replaced. Replaced only with the same or

equivalent type.

Notes on the lithium battery

ˎKeep the lithium battery out of the reach of children.

Should the battery be swallowed, immediately

consult a doctor.

ˎWipe the battery with a dry cloth to ensure a good

contact.

ˎBe sure to observe the correct polarity when installing

the battery.

ˎDo not hold the battery with metallic tweezers,

otherwise a short-circuit may occur.

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 using NFC

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

part of the smartphone again.

Notes

ˎWhen making the connection, handle the

smartphone carefully to prevent scratches.

ˎOne-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 assy (Ref. No. FP1) is replaced, it is neces-

sary to afﬁx the label (serial number).

2 labels (serial number) are included with a new front panel assy

(Ref. No. FP1). Afﬁx 1 label to the rear side of the front panel assy

(Ref. No. FP1). 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 assy (Ref. No. FP1)

and main unit do not match.

Also, since the serial number has changed, print page 15 and hand

the tear-off with the product to the customer when returning the

product after repairs are complete.
