1. How to Start the CD Test Mode
While pressing the FUNCTION button, insert the AC plug to the power outlet.
When the test mode is started, the message [TEST] is displayed.
2. How to Exit the CD Test Mode
Press the POWER button or disconnect the AC plug.
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.
