2. Setup
2.1 Charging the Battery
Before initial use, fully charge the iGP-100's internal lithium-ion battery. Connect the device to a power source using the provided USB cable and a compatible USB power adapter (not always included) or a computer's USB port. The battery indicator on the LCD will show charging status. A full charge provides up to 12 hours of continuous playback.
2.2 Connecting to a Computer
To transfer music files, connect the iGP-100 to your computer using the supplied USB 2.0 cable. The device will be recognized as a removable storage drive, similar to a hard drive. No special driver software is typically required for Windows ME/2000/XP or later operating systems. For older operating systems like Windows 98, specific drivers might be necessary.
2.3 Transferring Music Files
Once connected, simply drag and drop your music files (MP3, WMA, ASF, Ogg Vorbis) from your computer's folders directly into the iGP-100's music folder. Organize your music into folders as desired for easier navigation on the device. After transferring, safely eject the device from your computer before disconnecting the USB cable.

4. Maintenance
4.1 Cleaning Your Device
Wipe the exterior of the iGP-100 with a soft, dry, lint-free cloth. Do not use liquid cleaners, aerosols, or solvents. Avoid getting moisture into any openings.
4.2 Battery Care
To prolong battery life, avoid exposing the device to extreme temperatures. If the device will not be used for an extended period, charge it to about 50% before storing. Recharge periodically if stored for very long durations.
4.3 Firmware Upgrades
iRiver may release firmware upgrades to enhance features or improve performance. Check the official iRiver support website periodically for available updates and follow the provided instructions carefully for installation.
5. Troubleshooting
- Device does not power on: Ensure the battery is charged. Connect to a power source and try again. Check if the Hold switch is engaged.
- No sound: Check the volume level. Ensure headphones are properly connected. Test with different headphones if possible.
- Computer does not recognize the device: Ensure the USB cable is securely connected to both the device and the computer. Try a different USB port or cable. Restart your computer and the iGP-100.
- Music files not playing: Verify that the files are in a supported format (MP3, WMA, ASF, Ogg Vorbis). Ensure the files are not corrupted.
- Short battery life: Ensure the battery is fully charged. Reduce screen brightness if adjustable. Avoid extreme temperatures. Battery performance naturally degrades over time.
