We recently saw a few cases where after updating a G10TII transmitter, it became non-operational. We believe the root cause is this: Line 6 Updater 1.19 unexpectedly identifies G10TII devices as G10T devices. Due to this, it is possible that one could load G10T firmware 1.06 on a G10TII product. If one ever gets into a state where they incorrectly load G10T firmware onto a G10TII, as described above, the issue can be remedied by downloading and installing the latest Line 6 Updater (version 1.20 or later – the latest version is now 1.23) and using it to re-update the G10TII back to the G10TII firmware. As of this writing, the only G10TII firmware release is the initial public firmware (2.00.0). NOTE: If the G10TII does not appear in Line 6 Updater after a few seconds, try un-docking/re-docking the unit a few times to see if it might then be recognized.

Relay G10TII Information Important Information About the G10TII Transmitter · The recommended charging temperature range of the G10TII transmitter is specified as 50° F to 86° F (10° C to 30° C). · The recommended operating temperature range of the G10TII transmitter is specified as 32° F to 122° F (0° C to 50° C). · Line 6 recommends charging the G10TII transmitter at least every 6 months, based on best practices for lithium-ion batteries. · G10TII LED behavior is as follows: G10TII Transmitter (Docked in G10/G10S Receiver, POD Go Wireless, Spider V amp or THR10II/THR30II/THR30IIA Wireless amp)* LED State Condition Red (slow flash) Charging, less than 30 minutes battery time remaining † Green (slow flash) Charging, more than 30 minutes battery time remaining Green (solid) Fully charged ‡ Dim Red/Pink, may turn off G10TII is not docked properly – Try un-docking and re-docking 5-10 times Red (three quick flashes, repeating) G10T charging has stopped due to exceeding supported temperature. Charging will resume after 5 minutes at 50° F to 86° F (10° C to 30° C) § Orange (solid) Docked and connected to Mac or PC, firmware update in progress Off Receiver not powered (transmitter enters sleep mode after 4 minutes if receiver power is disconnected) G10TII Transmitter (Connected to Instrument) LED State Condition Green (solid) Transmitting, more than 30 minutes battery time remaining Red (slow flash) Transmitting, less than 30 minutes battery time remaining Off Connected to an instrument but not enough battery to transmit ‖ or Removed from instrument *When the G10TII is docked in a receiver or Relay-Ready device, the G10TII LED initially indicates amber, red, or green, depending on its current battery state. This is followed by four flashes (red) as the device initializes. Once this completes, the G10TII LED proceeds to indicate its remaining battery time. † All values stated for amount of battery time remaining are approximate, and the exact amount of battery time remaining when an LED state is indicated may vary slightly between charges. When the G10TII flashes red, it may have up to 60 minutes of battery time remaining. ‡ If the G10TII reaches a full charge (solid green) and remains docked, the G10TII LED may eventually flash green again. This is expected behavior as the G10TII may discharge slightly after reaching a full charge, and its LED may then flash green until it again reaches a full charge. § If the charging lockout indication continues for over 10 minutes, please stop charging and try again in a cooler environment condition. ‖ When the G10TII has insufficient power to transmit, its LED may indicate a pattern of five quick red flashes when connected to an instrument and audio is detected. This is the expected behavior.
