(2) Service clearance
Figure 3.7 shows locations which must be accessed for installation and maintenance. Be sure to
leave sufficient service clearance.

(3) External magnetic fields
Mount the optical disk drive away from powerful magnetic materials (e.g., a speaker) to avoid
influence from the front side of magnetic fields.
(4) Leak magnetic field
The VCM drive magnetic circuit may leak the magnetic field (Maximum 25 Gauss at distance of
4 mm from the drive).
Do not place a device sensitive to a magnetic field near the optical
disk drive.
(5) External light source
Mount the optical disk drive away from strong light sources (e.g., camera flash).
(6) System ground
The optical disk drive should be grounded to the signal ground (SG) of the power supply of the
system. This SG line should be supplied with the system.
