Front Panel Display
The power supply has a front panel screen saver that significantly increases the life of the LCD display
by dimming it during periods of inactivity. The delay can be set from 30 to 999 minutes in 1 minute
increments. As shipped, the screen saver comes on one hour after activity on the front panel or
interface has ceased.
When the screen saver is active, the front panel display turns off, and the LED next to the Line switch
turns from green to amber. To restore the front panel display, simply press one of the front panel keys.
The first action of the key turns the display on. Subsequently, the key will revert to its normal function.
If the Wake on I/O function is selected, the display is restored whenever there is activity on the remote
interface. This also resets the timer on the screen saver. As shipped, Wake on I/O is active.

Front Panel Lock-Out
You can lock the front panel keys to prevent unwanted control of the instrument from the front panel.
This is the most secure way of locking the front panel keys because you need a password to unlock the
front panel. This parameter is saved in non-volatile memory. Therefore, the front panel remains locked
even after AC power is cycled.

panel. Then select Lock.
