Error 04 my jvc kd-s630 is displaying 'error 04' I cannot ejct the cd, I can't turn it off, I can adjust the volume and audio controls, but there is only static from the speakers. How do I solve error 04??

Is it KDG200 or KDG116?
In KDG200, press and hold SEL to display menu
Turn volume knob or press fwd or rev buttons to select CLOCK H and set.
Press Volume knob to save.

In KDG116, instead of turning the volume knob, use +/-. Instead of pressing the Volume knob use SEL

to set the clock on the JVC kdg230 you press and hold the display button till the hour digit blinks use the volume controller to adjust the hour to set the minutes , after setting the hour press the sel. button and repeat the same for adjusting the minutes i didn't see where am or pm was selectable

The cord you are using is an audio cable with a 3.5mm plug with two black bands on the plug. The JVC Source button has to be pressed until AUX shows in the display. The volume on the iPod AND the volume on the deck affect the sound - turn the iPod up to 70% volume for best results.

Hello hawk713, Like with many other JVC receivers, adjusting the bass is done from the "EQ" (equalizer) mode for one or all of 6 presets: ROCK, CLASSIC, JAZZ, HIP HOP, POPS, and USER. To adjust it, select the desired preset mode, use the left/right rocker (on volume control) to scroll to the desired frequency, 60, 150, 400, 1K, 2.4K, 6K, and 15K, and then turn the volume control up/down to set a level from -5 to +5. 60 and 150 adjusts the bass, 400, 1K, and 2.4K adjusts the midrange, and 6K and 15K adjusts the treble. Then you select whichever EQ setting sounds best with the particular music you're playing. Hope this helps.

Hello atesha23,

Below is the step-by-step procedure for setting the JVC clock. Please note that after you have entered the PSM mode, if you have not pressed a button for about 2 seconds, the radio will automatically exit the mode and return to normal operating mode. In that case, you must restart PSM by holding the "SEL" button until the display changes.

(1). Enter the PSM mode by pressing and holding the
SEL button until the display changes.
(2). Use the rocker switch left/right until "CLOCK
H" is displayed.
(3) Set the clock hours by turning the volume
control up/down.
(4) Press the rocker switch again until "CLOCK M"
is displayed.
(5) Set the clock minutes by turning the volume
control up/down.
(6) Press the SEL button to finish and EXIT.

Hope this helps.

Push the Sel button and hold for 3 seconds (usually displays Demo or Demo Off). Push the Station up and down button til it reads Clock H or Clock M. Turn the volume button to adjust time. Push the Sel button to quit.
