Fig. 9-9. Operation Information
According to the above example, the optical system operation time
is 12 hours, 30 minutes, and 47 seconds.
The received SIRCS is counted separately for [key] and [remote
control]. For example, STOP, the number of times received for [key]
is 3Dh=61 times and that of [remote control] is 22h=34 times.

3. SERVICE MODE
3-1. Setting the Service Mode
To set the service mode, perform the following process.
With the power off, press the following three keys of the unit simul-
taneously and start up the power.
[STOP]+[10] + [POWER]
If the microprocessor version is displayed on the screen, it indi-
cates that the service mode is set.
If it is not displayed, it indicates that the mode is not set.
When the service mode is set, the debug mode will also be set at the
"
same time from the beginning.
"
"
3-2. Exiting the Service Mode
"
To exit, press POWER and turn off the power.
"
If it cannot be turned off (when the mechanism has not been com-
"
pleted, etc.), press the [STOP] key and [POWER] key of the unit
"
simultaneously and turn off the power forcibly.
3-3. Using Special Operations
For safety, the special operations in the service mode can only be
performed in the [NO DISC] and [STOP] state. Check that the above
message is not blinking but displayed on the screen. So as to valid
the debugging commands at the debugging mode, press the [10/0]
key and then the [8] key of the remote control while pressing the
[STOP] key of the unit. And the Fluorescent tube will be off while
debug commands are effective, and after the Fluorescent tube goes
off, keys of the unit such as [PLAY] and [PAUSE] are pressed, the
special functions in Table 9-10 can be performed.
Operations by other keys are continuously performed once the keys
are pressed until the [STOP] key is pressed.
Several special operations cannot be performed at the same time
even by pressing more than two keys together.
As some keys will not function while the Fluorescent tube is off, to
stop special operations from being performed. So as to invalid the
debugging commands at the debugging mode, press the [10/0] key
and then [9] key of the remote control while pressing the [STOP]
key of the unit. The Fluorescent tube will be on while debugging
commands are not effective.
