Maintenance
Charging the G10TII Transmitter
To maintain optimal performance, regularly charge your G10TII transmitter. Simply plug it into the G10S receiver's input jack. The receiver acts as a charging dock. A full charge typically takes 1-2 hours.
Storage
When not in use, it is recommended to unplug the G10TII transmitter from your instrument and store it in a safe place, ideally within its original case or a protective bag. This helps preserve battery life and protects the unit from damage.
Troubleshooting
Signal Drop or Interference
The Relay G10S operates on the 2.4GHz frequency band, which is also used by Wi-Fi networks and other wireless devices. If you experience signal drops or interference:
- Check Line of Sight: Ensure there are no major obstructions (e.g., walls, large metal objects, human bodies) between the transmitter and receiver.
- Minimize Interference: Try to operate the system away from active Wi-Fi routers, cordless phones, microwave ovens, or other 2.4GHz devices.
- Change Channel: While the system auto-selects, manual channel selection might help in congested environments. Refer to the G10S receiver controls for manual channel adjustment.
Charging Issues
If your G10TII transmitter is not charging:
- Ensure Proper Connection: Make sure the transmitter is fully seated in the receiver's input jack.
- Check Receiver Power: Verify that the G10S receiver is powered on.
- Firmware Update: In some cases, charging issues can be resolved by updating the firmware of both the G10TII and G10S units. Visit the Line 6 support website for the latest firmware and instructions.
