This is a question about my Dynamic Gain Controller GML 8900:
Sometimes , when I switch on, the gain control indicator is at the leftmost position (red), although there is no signal fed. Also the crest-factor is all red. After a while, (several hours) the indicator comes back to normal position, like when no signal is indicated. Where does this come from. Is this a sign of a damage?
BTW: is there a certain time when the device should get maintenance?
Thank you for your answers.
