FLUORESCENT INDICATOR TUBE AND LED
CHECK MODE
This mode is set by pressing the I/u button while pressing the
[CHECK] and [PLUSONE] buttons in order in the power-off
(standby) state.
The whole fluorescent indicator tube lights up, and the
[STANDBY],
[MEGACONTROL], [GROUP1-5], [PLUSONE], · and
P LEDs light up.
This mode can be exited by pressing the I/u button.
SHIPMENT MODE
(Set to this mode when returning the unit to the
user.)
This mode is set by pressing the I/u button while pressing the
[PUSHENTER] and [PLUSONE] buttons in order in the power-
off (standby) state.
The power goes off automatically after the SRAM is all-erased
and the BD is opened (loading out state).
Test points and connecting points:
[MAIN BOARD] – CONDUCTOR SIDE –
AGING MODE
• Mode which repeatedly changes and plays back discs automati-
cally in the unit.
• It will repeat aging as long as no errors occur.
• If an error occurs during aging, it will stop all servos, motors,
etc. instantaneously, display the error number, and stop opera-
tions. However, the stopping conditions differ according to
whether the unit is equipped with the “self-protection function
during errors” described later.
The function serves to maintain the state of the unit when errors
occur.

Special Functions in Aging Mode
There are some useful function in the aging mode.
• Disc setting mode*1
• Switching of use/disuse of protection function in errors *2
• Aging cycle count function *3
*1 Disc setting mode:
5 discs are set before setting the aging mode. This mode makes
the setting of these discs more easy.
*2 Switching of use/disuse of protection function in errors:
Function which voluntarily corrects errors which occur dur-
ing normal operations by retries.
If this function is not provided, all operations will be stopped
without retiring. It is suitable for checking errors with low re-
producibility.
If this function is provided, and errors can be corrected by
retries, aging will be continued without stopping.
(The normal aging should be performed with “be”.)
