outlet
• Insert the power plug firmly into the AC outlet.
SYMPTOM POSSIBLE CAUSE SOLUTION
Disc play does not start • The disc is loaded upside down
• The disc is too dirty
• Reload the disc with the label side UP
• Clean the disc
No sound • Incorrect audio cable connections
• Incorrect amplifier/receiver operation
• Connect the CD player to the amplifier/receiver
correctly
• Make sure that the input selector on your
amplifier or receiver is set to CD
Sound skips • The CD player is subject to vibration or physical
shock from external sources
• Change the installation location
Remote control does not work • Batteries in Remote Control handset have
expired

on the player
• Replace batteries
• Remove any objects directly in front of the player
A “humming” sound can be heard • Loose cable connections • Check the cable connections, particularly the
phono connecting cables
ABOUT THE OPTICAL PICKUP
The Compact Disc player uses a solid-state semi-conductor diode laser,
mounted on a tracking servo-mechanism, to play the disc. The laser
illuminates the track of microscopic pits representing the digital data
bits, while photo-diodes detect the reflected illumination from the disc
and convert it into an electronic signal which is then decoded to recover
the musical waveform in each stereo channel.
You cannot see the laser operating, because it operates at wavelength
of 7800 Angstroms, which is in the infrared and thus invisible to the
human eye.
The Compact Disc player is completely safe for children to use. The laser
operates at very low power and is concealed within the player
mechanism. Even when the player is disassembled, the laser remains
sealed within an optical system that causes its light to focus only 1
millimeter from the lens and then diverge rapidly, reducing its intensity
to negligible levels.
