PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
This set employs laser. Therefore, be sure to follow carefully
the instructions below when servicing.
WARNING!!
WHEN SERVICING, DO NOT APPROACH THE LASER
EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS
NECESSARY TO CONFIRM LASER BEAM EMISSION.
BE SURE TO OBSERVE FROM A DISTANCE OF MORE
THAN 30cm FROM THE SURFACE OF THE OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.
Caution: Invisible laser radiation when
open and interlocks defeated avoid
exposure to beam.
Advarsel:Usynlig laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.
VAROITUS!
Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa
mainitulla tavalla saataa altistaa käyt-täjän
turvallisuusluokan 1 ylittävälle näkymättömälle
lasersäteilylle.
VARNING!
Om apparaten används på annat sätt än vad som
specificeras i denna bruksanvising, kan användaren
utsättas för osynling laserstrålning, som överskrider
gränsen för laserklass 1.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herin may result in
hazardous radiation exposure.
ATTENTION
L’utillisation de commandes, réglages ou procédures
autres que ceux spécifiés peut entraîner une dangereuse
exposition aux radiations.
ADVARSEL
Usynlig laserståling ved åbning, når sikkerhedsafbrydereer
ude af funktion. Undgå udsættelse for stråling.
This Compact Disc player is classified as a CLASS 1
LASER product.

Precaution to replace Optical block
(VED0375-TN)
Body or clothes electrostatic potential could
ruin laser diode in the optical block. Be sure
ground body and workbench, and use care the
clothes do not touch the diode.
1) After the connection, remove solder shown in
right figure.

NOTES
• PCMD is a MSB first, two's complement output.
• GTOP is used to monitor the frame sync protection status. (High: sync protection window released.)
• XUGF is the frame sync obtained from the EFM signal, and is negative pulse. It is the signal before sync
protection.
• XPCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge and the EFM
signal transition point coincide.
• The GFS signal goes high when the frame sync and the insertion timing match.
• RFCK is derived from the crystal accuracy, and has a cycle of 136µs.
• C2PO reqresents the data error status.
• XROF is generated when the 16K RAM exceeds the ±4F jitter margin.
