• Do not insert the CD disc when checking the search mode.
• Press the REPEAT key to release each mode.
* NOTE 1 : There is a case that the CD cannot be operated owing to the protection circuit being operated when heat builds up in the driver IC if
the focus search is opereated continually for more than 10 minutes.
In this case, the power supply should be switched off for 10 minutes until the heat has been reduced and then re-start.
