Frequently Asked Questions - D20 COWON

How long does the battery take to charge?

USB charging takes about 6 hours (5V/500mA), while an approved AC adapter charges in about 3 hours (4.2V/750mA). Always use COWON-approved chargers.

Why won't the device turn on?

Ensure the battery is charged. If it’s completely discharged, charge it for a few minutes. If still not working, press the RESET button on the back. Reset only disconnects power and does not delete data.

How do I reset the device?

Press the RESET button on the back using a thin object. This only shuts off power in case of malfunction and does not affect performance or stored files.

Can I use a MicroSD card with the D20?

Yes, the D20 supports MicroSD, SDHC, and MMC cards. The maximum number of files per card is 12,000 folders and 12,000 files (8,000 music/video + 4,000 others).

The touchscreen or buttons are unresponsive.

Why are my video files not playing?

Ensure video format is AVI, WMV, or ASF with recommended resolution 320x240 and 30fps. If incompatible, use a conversion program like JetAudio. Also verify the file is not corrupted.

How do I update the firmware?

Download the latest firmware from www.COWON.com. Connect the D20 via USB, unzip the firmware file, and copy it to the root folder. Then safely eject and restart the device. The update will start automatically. Keep the battery fully charged and do not turn off during update.

+ Troubleshooting

+ I am still confused even after reading the manual.

COWON website (www.COWON.com) provides support for users of COWON products with FAQ (Frequently Asked Questions) Users are strongly encouraged to check out the website for further information regarding product usages and firmware upgrades. For individual inquiries, please contact us on-line as we will try to help you as best as we can.

+ I would like to set the device as factory default.

To reset all settings to factory default, go to SETTINGS ▶ System ▶ Load Defaults.

+ The player does not turn on.

Check if the battery is recharged or the device is connected to a power source. If the battery is completely discharged, charge the battery before you start the player. The charging time may vary depending on the battery's discharge status. If the player does not work at all, press the RESET button. For your information, RESET will just disconnect the power and does not damage the product or delete any files stored on the device.

+ The touch pad and buttons do not work properly.

The device does not respond to touch when the touch screen is on Hold. Press the Power / Hold button briefly to inactivate Hold mode.

Additional

+ Troubleshooting

+ I can't hear any sound.

Check if the volume is set to "0". Check if there is any file available in the player. If there is no file in the player, you will not hear any sound. Please note that corrupted files will result in a noise or discontinued playback. Make sure the earphones are connected properly. Impurities in the earphone jack can cause a static noise.

+ Files that I have stored do not appear in the list.

Each mode shows you a list of playable files only. To view all files that you have stored, select the Browser mode. Please note that System folder will not appear in the Browser.

+ Album image is not displayed in Music Mode.

To display an album image, the music file must have an image stored in its ID3 tag. Please save an image in the file using a program for editing ID3 tags. D20 supports Album Art 2.0 and you can store up to 6 album images.

+ Video won't play.

Make sure that your files are in a format that D20 supports (check the codecs/resolution/options). If you're unsure of a video's compatibility, use a video conversion program (e.g. JetAudio) and then play the converted version.

Additional

+ Troubleshooting

+ 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.

Additional

+ Troubleshooting

+ 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 10 MB of space for saving settings and other system files.

+

'EJECT' procedure must be performed before removing the device from the PC.

The device can malfunction with MAC OS 10.5 Leopard version or later. If the device shows a problem, format it as FAT and install the latest firmware.

+ Battery Replacement

Gray icon of a battery with lightning bolt inside a circular arrow, symbolizing energy or recycling (no text)

The rechargeable batteries have limited number of charge cycles, and it will require a replacement as capacity to hold power will eventually diminish.

The rechargeable batteries in COWON products should be replaced only by official COWON service centers. Please contact [e-mail] for more information on official COWON service centers.

+ Product Disposal

Symbol of a trash bin crossed with a diagonal line, representing waste or discharge (no text or numbers present)

COWON products contain built-in rechargeable batteries, and must be separately disposed from household waste.

Disposing the products with regular waste may cause pollution to the environment due to the waste batteries inside. Contact your local authorities for specified locations / guidance of E-waste and waste batteries, and dispose them in compliance with local regulation / guidance.
