Power

Apply power by connecting the power cord to an AC source. The switcher

performs a self-test that ﬂashes the front panel button indicators green, red, and

amber and then turns them off. (The order in which the colors are displayed

dependsonthemodel.)Anerror-freepowerupself-testsequenceleavesallI/O

status of the RGBHV or Video button and the Audio button is deﬁned by the

system conﬁguration as follows:

• Audio models —RGBHV/VideoandAudiobothlit

• Models without audio —RGBHV/VideolitandAudiounlit

The current conﬁguration and all presets are saved in non-volatile memory. When

power is applied, the most recent conﬁguration is retrieved. The previous presets

remain intact.
