Speaker check:
Turn the Ignition switch to the "ACC" or "ON" position and switch off the radio and CD player.
Press the following buttons in that order within sixty seconds from step above
(1) [CH1] button
(2) Fast-reverse/Track down button
(3) Fast-forward/Track up button
(4) [CH6] button
Check that the speaker, which is displayed on the center panel display, sounds (If the [CH6] button is pressed, the speaker will be changed).
The display of "FL", "FR", "RL", "RR" blinks. If no speakers sound, any of the speaker circuits is short-circuited.
If a button other than the [CH6] button is pressed, or the ignition switch is turned to "LOCK" (OFF) position, you will exit from the speaker connection check mode.
