In some cases when docking G10TII in a receiver for firmware update, the transmitter LED may briefly indicate green before changing to flashing red. This is normal. If the transmitter is docked in the receiver device, and the receiver is powered off or power is disconnected (e.g., connected power strip is turned off), the transmitter will enter sleep mode after 4 minutes. When the receiver is powered on again, the transmitter must be un-docked and re-docked before charging will resume. Powering a G10 receiver or G10S receiver from the USB port of a Mac or PC is not supported (this may or may not work, but cannot be guaranteed as it depends on the amount of current available from the computer). If POD Go Wireless is connected to a Mac or PC with the Line 6 Updater app open, and a G10T or G10TII transmitter is docked in the POD Go Wireless, it may take several seconds before the transmitter appears within the Line 6 Updater window. For users of the original G10T transmitter only, the G10S receiver’s battery LED segment will now indicate a solid red LED for the low battery state, without flashing. Each time the G10TII transmitter on the 2.05.0 firmware is docked in a receiver device, the G10TII LED will flash red for 3 minutes while the device’s battery data is read. This will occur even if the G10TII is already at or near a full charge (after that 3 minutes, a transmitter that is at or near a full charge would change to flashing green and eventually to solid green, depending on its charge level).

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.

We have designed the G10T and G10TII transmitters to fit into almost any guitar. However, we anticipate that there will be some rare cases where the transmitter does not fit into a given guitar. If the G10T or G10TII transmitter is inserted into your guitar and the transmitter's actuator pin is not engaged, the transmitter will not turn on, the LED on the transmitter will not light up, and no signal is processed. In some rare cases, the guitars active electronics are wired with inverse polarity. In this scenario, the original G10T transmitter's electronics can go into a protection mode that keeps the system from being functional. This is evidenced by no output from the receiver, even though the transmitter's light is on. The new G10TII is designed to be electrically compatible with instruments using active pickups and preamps, without the need for an adapter. In some other cases, such as with the Line 6 Variax Acoustic 300, voltage can build up in the ring of the guitar's jack to the point of "tricking" the transmitter into thinking it is docked in the receiver and charging, also resulting in no audio output. Additionally, certain instruments may present a level of noise when their active circuitry is engaged and the transmitter is connected. We have found that a workaround to all of these issues is to use a mono-to-mono (TS-TS) Male to Female adapter, such as those shown below. The G10 transmitter is shown for scale. More details about the first two of these issues are included in the attached document. Troubleshooting procedure: Power the receiver with a USB power source. Insert the transmitter into the receiver (this will ensure that the transmitter and the receiver are set to the same channel). The LED on the transmitter should be Green or Green flashing. (If it is red flashing, the transmitter needs charging. Leave it in the receiver until the LED turns steady green. That indicates it is fully charged.) Insert the transmitter into the instrument's jack, turn up the volume control and play. If audio is not being transmitted to the receiver: A. The problem is mechanical if the LED on the transmitter is OFF when plugged into an instrument. B. The problem is electrical if the LED on the transmitter is ON, or FLASHING when plugged into an instrument Relay G10 Guitar Compatibility.pdf
