Panel Lock
The panel lock feature prevents settings from being changed
accidentally. When activated, all keys and knobs except the
Lock/Unlock key and the Output key (if active) will be disabled.
If the instrument is remotely controlled via the USB/LAN/RS-
232/GPIB interface, the panel lock is automatically enabled. See
page 153 for remote control details.
Press the Lock key to active the
panel lock. “Keys locked” appears
on the display.
A lock icon will appear in the top
corner when the panel keys are
locked.
Hold the Lock key for ~3 seconds to
disable the panel lock. “Keys
unlocked” will appear on the
display and the padlock icon will
disappear.
