÷ When servicing this model, some service procedures may reset the customer settings

to the factory default settings. Make sure to explain this to the customer.

An HDD (Hard Disc Drive) is mounted in this product.
The HDD is a precision instrument very vulnerable to shock and electrostatic charges. Please read
"7.3 Cautions on Handling the HDD" in this manual and exercise sufficient caution when handling the
HDD itself, as well as the product with the HDD built in.
When an HDD becomes defective and inoperable, restoration of the user's data recorded on the HDD,
or copying of the user's recorded data to other media (such as a new HDD) is totally impossible.
Before servicing, OBTAIN THE USER'S PRIOR CONSENT to that effect.
The user must be made aware that all recorded data are deleted if the HDD is intialized.

Additional Laser Caution

1. The ON/OFF(ON:low level,OFF:high level) status of the
CLAMP signals for detecting the loading state are detected
by the drive CPUs, and the design prevents laser diode
oscillation when the CLAMP signal turns OFF.
In normal operation, if no disc is clamped, the laser diode
oscillation is disabled.
However, the interlock does not always operate in the test
mode.

2. When the cover is opened, close viewing of the objective

D

lens with the naked eye will cause exposure to a Class 3A
laser beam.
