Charging the Device
Before first use, fully charge your Coby MP620. Connect the included USB cable to the player's USB port and the other end to a powered USB port on your computer or a compatible USB wall adapter (not included). The integrated rechargeable Li-Poly battery provides up to eight hours of music playback on a single charge. Charging typically takes approximately 1 hour via a wall outlet (if using a compatible adapter).
Connecting to a Computer and Media Syncing
The Coby MP620 uses USB 2.0 for fast file transfers. To transfer media, connect the player to your computer using the supplied USB cable. You have two primary methods for syncing media:
- Using Coby Media Manager Software: The included Coby Media Manager software allows you to convert existing audio and video clips to the correct formats for optimal playback on your device. Install the software from the provided disc or download it from the official Coby website. Follow the on-screen instructions within the software to manage and transfer your files.
- Drag-and-Drop: Alternatively, you can treat the device as a standard storage drive. Once connected, the player will appear as a removable disk drive on your computer. You can then drag and drop compatible audio, video, photo, and text files directly into the appropriate folders on the device. Ensure files are in supported formats (MP3/WMA for audio, MTV for video, JPEG/BMP for images, TXT for text).

Maintenance
To ensure the longevity and optimal performance of your Coby MP620, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the device. For stubborn smudges on the screen, a slightly damp, lint-free cloth can be used. Avoid using harsh chemicals or abrasive cleaners.
- Storage: Store the player in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Handle the device with care to prevent drops or impacts, which can damage internal components or the screen.
- Battery Care: To maintain battery health, avoid completely draining the battery frequently. Charge the device regularly, especially if it will be stored for an extended period.
Troubleshooting
If you encounter issues with your Coby MP620, refer to the following common troubleshooting steps:
- Device Not Turning On: Ensure the battery is sufficiently charged. Connect the player to a power source and allow it to charge for at least 15 minutes before attempting to power it on again.
- No Sound: Check that the volume is not set to minimum or muted. Ensure the earphones are securely plugged into the headphone jack. Test with a different pair of earphones to rule out faulty earphones.
- Cannot Transfer Files: Verify that the USB cable is properly connected to both the player and the computer. Ensure the computer recognizes the device as a removable disk. Try a different USB port on your computer. If using Coby Media Manager, ensure the software is installed correctly and up to date.
- Screen is Blank or Frozen: Try performing a soft reset by holding down the power button for several seconds until the device powers off, then power it back on. If the issue persists, allow the battery to fully drain and then recharge it.
- FM Radio Static: Ensure your earphones are fully plugged in, as they function as the antenna. Try repositioning the device or moving to an area with better signal reception.
