Front Panel Key Lockout Options
Perform the procedure in Figure 2-24 to lockout the front panel key functions. There are
three lockout features:
• Monitor Mode Lockout
• Review Mode Lockout
A third lockout can be enabled only from the computer interface (see the LOCK 3
command in Chapter 4).
The Monitor Mode lockout is entered when the instrument is in the Monitor Mode; the
Review Mode Lockout is entered when the instrument is in the Review Mode. When
lockout is enabled, the instrument becomes "locked" in a selected mode preventing any
unauthorized instrument operations. A repeat of the lockout keystrokes releases the
lockout and the instrument resumes normal operation. When in the locked condition, the
front panel REM indicator is on (dim). This feature allows inexperienced operators to
use the instrument without having to change the mode of operation. The keystrokes used
to enable or disable the lockout option is normally not revealed to unauthorized
personnel.
