Advanced Thermal Control
In this section, you can tailor the fan speed to specific applications. You have the choice of the following modes:
The fan mode can be changed using the front panel buttons at start-up or in the software. The default mode is normal and
should work fine for most applications. Early mode turns the fan on sooner at a "lower" temperature, and Full-speed mode
turns the fan on full-speed full-time. Full-speed mode is not recommended for "dirty" environments.

Advanced Monitoring

This feature allows you to have software visibility of both the Power Supply Temperature and AC Line voltage. AC Line
voltage is "derived" from the amplifier rail voltage and is an approximation of the AC line voltage. This allows you to monitor
the health of your amplifiers and provides for troubleshooting.

Front Panel Lock-Out

To disable or lock the buttons from the front panel, hold the Prev and Next at the same time until the screen says "locked".
The rotary knobs (attenuators) will still operate. To unlock, hold Prev and Next until the screen says "unlocked".
The front panel can also be locked out from the software as well from the main panel. However once it is locked in
the software, it can only be unlocked from the software. You cannot unlock from the front panel. The rotary knobs
(attenuators) will still operate.
