• 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 Lockmode2.
See “Setting the front panel locks (Executivemodes)”onpage3-46foradetailedlist
of basic and advanced functions and the procedure to set the various front panel
locks.
Power
Apply power by connecting the power cord between the switcher and an AC
source. The switcher performs a self-test that flashes the front panel button
indicators red, green, and amber and then turns them off. An error-free power-up
self-test sequence leaves all input, output, and control buttons either unlit or
showing background illumination and the Video button and the Audio button lit.
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
