While pressing the FUNCTION button, insert the AC plug to the power outlet.
When the test mode is started, the message [CD TEST] is displayed.

2. How to Exit the CD Test Mode

Press the POWER button or disconnect the AC plug.

* When any key other than PLAY is pressed during play mode, the machine exits the test mode.

3. Function Descriptions and Application of the CD Test Mode

*1: The driver IC heats up and the protection circuit starts working when the focus search is continued for 10 minutes or longer.

There can be a case that operations can not be performed correctly.
In such a case, turn off the main power. After cooling down the machine, restart the machine.

*2: Be careful not to damage the gear because the sled motor rotates while the FF or RWD button is being pressed even if the

pick-up is located in the innermost track or the outermost track.
