future reference.
- All warnings on the appliance and in the operating instructions
should be adhered to.
- All operating and use instructions should be followed.
1. Water and Moisture - The appliance should not be used near
water - for example, near a bathtub, washbowl, kitchen sink,
laundry tub, in a wet basement, or near a swimming pool,
and the like.
2. Carts and Stands - The appliance

4. Wall or Ceiling Mounting - The appli-
ance should be mounted to a wall or
ceiling only as recommended by the manufacturer.
5. Ventilation - The appliance should be situated so that its
location or position does not interfere with its proper
ventilation. For example, the appliance should not be situated
on a bed, sofa, rug, or similar surface that may block the
ventilation openings; or, placed in a built-in installation, such
as a bookcase or cabinet that may impede the flow of air
through the ventilation openings.
6. Heat - The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances (including amplifiers) that produce heat.
7. Power Sources - The appliance should be connected to a
power supply only of the type described in the operating
instructions or as marked on the appliance.
8. Grounding or Polarization - The precautions that should be
taken so that the grounding or polarization means of an
appliance is not defeated.
9. Power - Cord Protection - Power-supply cords should be
routed so that they are not likely to be walked on or pinched
by items placed upon or against them, paying particular
attention to cords at plugs, convenience receptacles, and the
point where they exit from the appliance.
10.Protective Attachment Plug - If the appliance is equipped with
an attachment plug having overload protection. This is a
safety feature. See Instruction Manual for replacement or
resetting of protective device. If replacement of the plug is
required, be sure the service technician has used a
replacement plug specified by the manufacturer that has the
same overload protection as the original plug.
11.Cleaning - The appliance should be cleaned only as
recommended by the manufacturer.
12.Power Lines - An outdoor antenna should be located away
from power lines.

13.Outdoor Antenna Grounding - If an outside antenna is
connected to the receiver be sure the antenna system is
grounded so as to provide some protection against voltage
surges and built-up static charges. Article 810 of the National
Electrical Code, ANSI/NFPA 70, provides information with
regard to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna-dis
charge unit, size of grounding conductors,location of antennadischarge unit, connection to grounding electrodes and
requirements for the grounding electrode. See Figure 1.
14.Non-use Periods - The power cord of the appliance should be
unplugged from the outlet when left unused for a long period
of time.
15.Object and Liquid Entry - Care should be taken so that objects
do not fall and liquids are not spilled into the enclosure through
openings.
16.Damage Requiring Service - The appliance should be
serviced by qualified service personnel when:
a) The power-supply cord or the plug has been damaged; or
b) Objects have fallen, or liquid has been spilled into the
appliance; or
c) The appliance has been exposed to rain; or
d) The appliance does not appear to operate normally or
exhibits a marked change in performance; or
e) The appliance has been dropped, or the enclosure
damaged.
17.Servicing - The user should not attempt to service the
appliance beyond that described in the operating instructions.
All other servicing should be referred to qualified service
personnel.

Connecting speakers
If the TV or monitor is equipped with an S video input, make the S video connection in addition to the normal video
connection. The S video connection will provide higher quality picture playback.

SCART Specification(Europe model only) : Composite and Component Video output(DVD, Video)Audio L/R
Output(DVD only)
for EU version: optional
Before connecting
This machine is designed to reproduce optimum sound quality when speakers with the specified impedance below
are connected. Please check the following information and choose speakers with appropriate impedance for the
connections.
Front speakers(L/R) :
XD-615/616/625/626[R] : 6 ohms min. per speaker
XD-618/628[R] : 8 ohms min. per speaker
To prevent damage to circuits, never short-circuit the positive (+) and negative (-) speaker wires.
Do not connect the speaker cable to the L and R connectors at the same time and do not connect more than one
speaker to the same speaker connectors.

Adjusting the position of the FM antenna
While listening to an FM program, extend the antenna and move it in various directions until the clearest signal is
received, then secure the antenna with push pins in the position with the least distortion.
Adjusting the position of the AM(MW) antenna
While listening to a AM(MW) program, set the antenna in the direction and position where you receive the clearest
sound.
Put it as far away as possible from the unit, TVs, speakers, cables, and power cords.
