Whwn I power up my system, t button is flashing. Is that ok?
Does the rest of the module appear to work normally?
Then it’s normal, I’m not sure what you mean by “flashing”, but the slow fade-out indicates that DEJA VU is at 12 o’clock, and a fast blink indicates that the channel is “super-locked” ie locked in a constant loop independently of the DEJA VU knob.
The states of the t/X buttons are saved whenever you change any other of the other mode buttons.
t was always lit (or flashing if it was at 12 o’clock) regardless if it was off last time I powered off the system. It’s ok now, I think it was a matter of a saved state.
