COWON A3
Troubleshooting
Symptom Explanation
Power does not turn on or is 
not working properly.
• If the built-in battery is or has been discharged, use the adapter to fully recharge it before use.
• If the player does not turn on after it is charged, press the “RESET” button on the bottom side of the player
 and then turn on.
• If the System folder is deleted, upgrade the firmware before use.
• Check to see if the switch on the bottom side of the player is placed to “HOLD”. If it is on “HOLD”, the 
 power button will not function.
Screen does not turn on even
after the player is powered on.
Check to see if the switch on the bottom side of the player is placed to “AV OUT”. If it is on “AV OUT”, move the switch 
to“LCD”.
System crashes during 
playback.
Perform a HDD check (chkdsk) before using. If HDD error is occurred, system may malfunction. Connect A3 to a 
PC. Type chkdsk e: /f at the cmd prompts. (Replace e: with the disk letter assigned to your A3 on your PC). For further

“X” displayed on the screen,  
and unit does not start after  
formatting.
You must format the unit in FAT32 format; otherwise system will not operate properly. Visit our website (www.CO-
WON.com) for the latest version of Firmware.
System doesn’t respond 
because system folder was 
deleted. 
If system folder was deleted, please visit our website (http://www.COWON.com) and download the latest firmware and 
upgrade before use.
Buttons don’t respond.
Make sure “HOLD” switch is set to off. “HOLD” switch is located in the bottom of the player.
Speaker does not work 
properly.
• Go to Setup - Sound - Speaker and check to see if it is set to Auto-Off or On. If it is set to Off, no sound is 
 heard from the speaker.
• Check to see if the volume is set to “0”, then adjust the volume.
Button operation does not 
respond quickly during movie 
or music playback.
This is because the player was set to Power Save mode to save battery power. Buttons will operate normally after 3 
to 4 seconds.
Nothing is heard from FM 
radio.
• FM radio reception may be poor or static may be heard depending where the player is used, such as inside  
 buildings, subways or moving vehicles. Listening to FM radio may be impossible in areas shaded from radio 
 transmissions.
• Check to see if the earphone is connected to the player. This player does not have a separate antenna, 
 therefore uses earphones as antennas to receive radio reception.
Noisy recordings
Noise from the HDD may be picked up by built-in microphone during recordings.  Also, due to limitation of digital 
devices, recorded audio may not sound normalized.
