Definition of Mechanical Mode

	No	MODE	DEFINITION & STATUS
	1	STOP MODE	- Disc haven’t been inserted or disc have been ejected. When disc shall be transported
			into the unit
			Mechanism shall be fixed at this mode.
			- Loading device can insert disc thru the slot.
			- Floating device being locked.
	2	LOADING	- Disc have been inserted thru the slot in front of unit. It is transient state between STOP
			mode and PLAY mode.
		MODE

-If disc should be inserted at the state of POWER ON, disc shall be loaded by a series of operation of specified device.

3 PLAY MODE - After disc have being clamped on the turn-table, disc shall be rotated.

-Disc shall be played.

-Floating device being unlocked.

4EJECT - Disc is to be ejected at this mode. It is transient state between PLAY mode and STOP MODE mode.

-If disc should be mounted at the state of POWER ON and commanded by EJECT key, disc shall be ejected thru the slot by a series of operation of specified device.
