Lockout.
The Lockout button is used to disable the keypad. While locked out,
pressing any key (except Lock Out or ON) produces the message press Lock Out
on the LCD display and has no other effect. While in Lock Out mode, a lock
symbol (padlock icon) appears in the lower right corner of the LCD display.
Bars and Other Signals.
The Bars and Other Signals buttons are used, along with
the alphanumeric keys, for selecting test signals. This occurs in the Signal Select
mode; the default operating mode for the PATHFINDER. The PATHFINDER
powers-up in this mode, and returns to it after exiting any of the other modes.
While in the Signal Select mode, the Bars button selects SMPTE Bars and 75%
Bars, and the Other Signals button scrolls through the remaining test signals. The
arrow keys will also scroll forward and backward through the signal list. In
addition, the alphanumeric keys may be used to select signals directly, eliminat-
ing the need to scroll through all the signals to get to the one you want:
