Adjustment Mode

A power source is put with pushing     and    .

ROM renewal mode

It is put with pushing a playback key and a still key.

When a power source is put with pushing a key.

When there is a disc Error rate display mode (There are a DVD and CD mode of it, and a disc is put, and a key manipulates.)
When there is

Test mode (Version display mode, color bar pattern display mode, mecha test mode.)

A power source is put.

[The flow of the test mode]

A power source is put, and closing, a playback key and a stop key are pushed for about two seconds at the same time

without a disk the disk cover. It goes into the (test mode.
