Storage: Store the R8 in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage.
SD Card Care: Always safely eject the SD card from the R8 before removing it. Regularly back up your data from the SD card to a computer.

Troubleshooting

Problem	Possible Cause	Solution
No power	Batteries drained or incorrectly inserted; USB power not connected or faulty.	Check battery polarity and charge/replace batteries. Ensure USB power adapter is working and connected securely.
No sound from outputs	Volume levels too low; incorrect input/output routing; headphones/monitors not connected or faulty.	Increase master volume and individual track faders. Verify input source selection and output connections. Test with different headphones/monitors.
Cannot record	Track not armed; SD card full or not inserted; input gain too low.	Press the REC button for the desired track. Insert/replace SD card. Adjust input gain.
Distorted audio	Input gain too high (clipping); incorrect input impedance (e.g., Hi-Z not selected for guitar).	Reduce input gain until PEAK indicator no longer lights. Ensure correct input type is selected (e.g., GUITAR/BASS for instruments).
