It has been found that some Relay® G10T wireless transmitters with v1.05 software may not be charged properly in hot environments.
The new update v1.06 ensures the correct charging behavior, as well as improving the LED response in a more accurate charging mode.
Update v1.06 also incorporates important security updates from version v1.05 released
in March of this year. We highly recommend updating v1.06 as soon as possible.

Dear customer,
It came to our attention that some Line 6 Relay G10 series products use lithium-ion batteries
may, in some very limited cases, overheat. See photos of the product below.

This overheating may result in a potential risk of fire or injury.
We carry out extensive tests in an external laboratory in order to determine the exact cause of this overheating. At this stage, we believe that you will only need a firmware upgrade for the product batteries to prevent them from overheating.
In the meantime, as a precautionary measure, if you own one of these models, stop using it immediately until you are provided with a firmware upgrade or other product instructions.
