tected, the detection information will not be written to the
E2PROM.
• While in the test mode, even after an elapse of pre-set time,
the backup memory items will not be written to the E2PROM.
• Information Clear mode for Test Mode, backup/installer
memory, and CD mechanism error log.
In the DC offset error detection information clear mode,
DEMO mode operation will not be conducted.
Also, in the above mode, the menu of the STANDBY source
will not display DEMO ON/OFF switching items.
• While in the test mode, and at the same time, PM_DET of
