DVD Player’s SCART jack to the corresponding
Scart input jacks on the TV (cable not supplied).
Note: –Ensure that the “TV” indication on SCART cable is connected to the TV set and “DVD” indication on SCART cable is connected to the DVD Player.
Step 2: Connecting speakers
1Connect the speaker wires to the SPEAKERS
terminals, right speaker to FRONT (4Ω) R and
left speaker to FRONT (4Ω) L. Fully insert the
connectors on the cables into the terminals and fasten the hooks to ensure firm connection.
2Connect the passive subwoofer to the
SUBWOOFER (8Ω)terminal with the supplied subwoofer cable by matching the plug types.
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 jacks. – Do not connect speakers with an impedance lower than the speakers supplied. Please refer to the SPECIFICATIONS section of this manual.

CONNECTION AND CONTROLS
Using Composite Video jack
1Use 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.
2To listen to the TV channels through this DVD
system, use the audio cables (white/red-not supplied) to connect AUX IN L/R jacks to the
corresponding AUDIO OUT jacks on the TV.
Using Component Video jacks (Y Pb Pr)
IMPORTANT! –The progressive scan video quality is only possible when usingY Pb Pr, and a progressive scan TV is required.
1Use component video cables (red/blue/green -
not supplied) to connect the DVD system's COMPONENT (Pr/Cr Pb/CbY) jacks to the corresponding Component video input jacks (or labeled as Y Pb/Cb Pr/Cr or YUV) on the TV.
2To listen to the TV channels through this DVD
system, use the audio cables (white/red-not supplied) to connect AUX IN L/R jacks to the corresponding AUDIO OUT jacks on the TV.
3If you are using a Progressive Scan TV (TV must
indicate Progressive Scan or ProScan capability), to activate TV Progressive Scan, please refer to yourTV user manual. For DVD system Progressive Scan function, see “Getting Started- Setting up Progressive Scan feature”.
Note: –If yourTV does not support Progressive Scan,
you will not be able to view the picture. Press SYSTEM MENU on the remote to exit the system menu and then DISC and “1” to exit progressive scan.
Using S-Video jack
IMPORTANT! –If S-Video is used for DVD playback connection, the system’s VIDEO OUT setting will need to be changed accordingly.
1Use an S-Video cable (not supplied) to connect
the DVD system’s S-VIDEO jack to the S-
Video input jack (or labeled asY/C or S-VHS) on theTV.
2To listen to the TV channels through this DVD
system, use the audio cables (white/red-not supplied) to connect AUX IN L/R jacks to the corresponding AUDIO OUT jacks on the TV.
Using an accessory RF modulator
IMPORTANT! –If yourTV only has a single Antenna In jack (labeled as 75 ohm or RF In), you will need an RF modulator in order to view DVD playback on theTV. See your electronics retailer or contact Philips for details on RF modulator availability and operations.
1Use the composite video cable (yellow) to
connect the DVD system’s VIDEO jack to the video input jack on the RF modulator.
2Use an RF coaxial cable (not supplied) to
connect ANTENNA OUT orTO TV jack on the RF modulator to the Antenna IN jack on the TV.
3Connect the Antenna or Cable TV service signal
to the ANTENNA IN or RF IN jack on the RF modulator. (It may have been connected to your TV previously. Disconnect it from the TV.)

CONNECTION AND CONTROLS
Step 5: Connecting FM antenna
1Connect the supplied FM antenna to the FM (75
Ω) jack. Extend the FM antenna and fix its end to the wall.
For better FM stereo reception, connect an
external FM antenna (not supplied).
Note: –Adjust the position of the antennas for optimal reception. –Position the antennas as far as possible from your TV,VCR or other radiation source to prevent unwanted interference.
Step 6: Connecting the power
cord
After everything is connected properly, plug in the AC power cord to the power outlet.
Never make or change any connection with the
power switched on.
Additional: Connecting additional equipment IMPORTANT! –Some discs are copy-protected.You cannot record the disc through aVCR or digital recording device. –When making connections, make sure the colour of cables matches the colour of jacks. –Always refer to the owner’s manual of the other equipment for complete connection and usage details.
Viewing and listening to the playback of other equipment A
●Connect the system's AUX IN L/R jacks to the
AUDIO OUT jacks on the other audio/visual device (such as a TV,VCR, Laser Disc player or cassette deck).
Before starting operation, press SOURCE on
the front panel to select AUX or press AUX on the remote in order to activate the input source. Using the VCR for recording DVDs B
●Connect one of the system's VIDEO jack to the
corresponding VIDEO IN jack and AUDIO OUT L/R jacks to the AUDIO IN jacks on the VCR.This will allow you to make analogue stereo (two channel, right and left) recordings. Recording (digital) C
●Connect the system's COAXIAL or
OPTICAL jack to the DIGITAL IN jack on a digital recording device.
Before starting operation, set the DIGITAL OUT
according to the audio connection. (See "DIGITAL OUT".)
Connecting an active subwoofer D
●Connect the DVD micro system's
SUBWOOFER jack to the AUDIO INPUT
jack on an active subwoofer (not supplied).
Connecting to a TV with HDMI Jack E
HDMI connects untouched and uncompressed
digital transmission for the highest and crispest sound/image quality.
It has plug and play capability using only one
cable for both audio/video output.
●Use a HDMI cable (not supplied) to connect the
HDMI jack on the DVD Player to HDMI IN on a HDMI compatible device (e.g.;TV, Projector, Adaptor).
➜It may take a while for the DVD player and
input device to communicate and initialise.
➜Playback starts automatically.
