My new Relay G10 is being used with a Yamaha THR30ii. The relay plugged into the amplifier for charging goes from red to flashing green, but will not reach a steady green glow. Both units have the latest firmware. Is the relay faulty if it never reaches the steady green glow when charging? I’ve only had the relay since early November and it’s never reached solid green once. Please advise as to whether or not it is defective and needs to be replaced before warranty expires. Thanks.
