FM Antenna
It is unnecessary to connect the FM pigtail
antenna since it is fixed to the main unit.
Adjust the FM antenna for optimal FM stereo
reception.
Step 4: Connecting TV
IMPORTANT!
–You only need to make one video
connection from the following options,
depending on the capabilities of your TV
system.
–Connect the DVD system directly to
the TV .
Using Video In jack (CVBS)
1 Use the composite video cable (yellow) to
connect the system's VIDEO jack to the video
input jack (or labelled as A/V In, Video In,
Composite or Baseband) on the TV set.
2 To hear the sound of this DV D Player through
your TV, use the audio cab les (white/red-not
supplied) to connect LINE OUT (L/R) jacks of
the DV D Player to the cor responding AUDIO
IN jacks on the TV.
Connections
Step 2: Connecting speakers
Connect the speak er wires to the SPEAKERS
terminals, right speaker to "RIGHT" and left
speaker to "LEFT", coloured (mar ked) wire to
"+" and black (unmarked) wire to "-". Fully inser t
the stripped por tion of the speaker wire into
the terminal as shown .
Notes:
– Ensure that the speaker cables are correctly
connected. Improper connections may damage the
system due to short-circuit.
–For optimal sound performance, use the
supplied speakers.
– Do not connect more than one speaker to any
one pair of +/- speaker terminals.
– Do not connect speakers with an impedance
lower than the speakers supplied. Please refer to
the SPECIFICATIONS section of this manual.
Step 3: Antenna connection
MW Antenna
Connect the supplied MW loop antenna to the
"MW AERIAL" terminal. Adjust the position of
the antenna for optimal reception.
Position the antenna as far as possib le from a TV,
VCR or other radiation source .

( right )
VIEWING AREA
Place the front left and right speakers at equal
distances from the TV set and at an angle of
approximately 45 degrees from the listening
position.
Notes:
–To avoid magnetic interference, do not position
the front speakers too close to your TV set.
– Allow adequate ventilation around the DVD
System.
IMPORTANT!
– The type plate is located at the rear of
the system.
– Before connecting the AC power cord
to the wall outlet, ensure that all other
connections have been made.
–Never make or change any
connections with the power switched on.
– The voltage selector located at the
bottom of this system is preset at
220V-240V from the factory. For
countries that operate at 110V-127V,
please adjust to 110V-127V before you
switch on the system.
To avoid overheating of the system, a
safety circuit has been built in. Therefore,
your system may switch to Standby
mode automatically under extreme
conditions. If this happens, let the system
cool down before reusing it (not available
for all ve rsions).

order to view the DVD playback via TV.
See your electronics retailer or contact
Philips for details on RF modulator
availability and operations.
1 Use the composite cable (yello w) to connect the
system's VIDEO jack to the video input jack on
the RF modulator .
2 Use an RF coaxial cable (not supplied) to
connect the RF modulator to your TV's RF jack.
Connections
Using S-Video In jack
1 Use the S-Video cable (not supplied) to connect
the system's S-VIDEO jack to the S-Video
input jack (or labelled as Y/C or S-VHS) on the
TV set.
2 To hear the sound of this DVD Player through
your TV, use the audio cables (white/red-not
supplied) to connect LINE OUT (L/R) jacks of
