COWON J3
+ Troubleshooting
+ Video won’t play.
Movie files that do not play properly on the product may
need to be converted by COWON MediaCenter - JetAudio.
+ FM Radio does not work.
The product’s earphones work as the FM Radio antenna.
Straightening the earphone cable will result in better radio
reception. FM Radio reception may be poor at locations
where FM Radio transmissions are shielded. If FM Radio
does not work where reception should be possible, please
contact our service center.
+ There is too much noise in my recordings.
The product uses ultra-small internal microphone, so it
may be more susceptible to noise during recordings. The
microphone should not be covered with anything during
recording.
+ Characters on the display are corrupted.
Set your preferred language again in Settings > Display >
Language. If the problem persists, set the current font to
the system font. COWON products are developed based
on the Korean Windows OS, and this may cause corruption
of some special fonts or languages on the display.
+ Computer cannot recognize the player when connected.
Try the RESET button in the back. If you experience a frequent
disconnection or unstable connectivity, connect the player
directly to the USB port of the PC, rather than a separate USB
hub. As COWON products use the USB connection for the main
power system, unstable power supply can cause a connection
failure.
+ Memory capacity of the player is different or smaller
than specified.
The memory capacity indicated by Windows may be different
from that indicated by the memory manufacturer. The actual
capacity will be reduced from the original size because some
space of the memory should be used as the system area for
normal operation.
+ The player does not play properly when memory is full.
For the player to function properly, it requires at least 5 MB of
space for saving settings and other system files.
