Front panel security lockouts
In the procedural descriptions that follow, it is assumed that the switcher is in Lock
mode 0 (fully unlocked). The following two Lock modes are also available:
• Lock mode 1 — All changes are locked from the front panel (except for setting
Lock mode 2). Some functions can be viewed.
• Lock mode 2 — Advanced features are locked and can be viewed only. Basic
functions are unlocked.

The switcher is shipped from the factory in Lock mode 2.
See “Setting the front panel locks (Executive modes)” on page 3-52 for a detailed list
of basic and advanced functions and the procedure to set the various front panel
locks.
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
and control buttons either unlit or showing background illumination. The lit/unlit
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.
If an error occurs during the self-test, the switcher locks up and does not operate.
If your switcher locks up on power-up, call the Extron S
