Operating Procedures
Using the Electronic Security Lock
To invoke the secure (locked) mode, the operator enters the Lock sequence (Right Alt
key, Right Shift key, and Enter key). The control unit displays
on the status line and
the display adds a
3
to act as a prompt for a user-definable three-key password to “unlock”
the display. To unlock, type in the three-key password. Each key decrements the prompt
number. If the password does not match, the
3
redisplays on the status line. When the
password matches, the display is unlocked and the control unit removes the
symbol.
Powering off the display while locked means it will be locked when powered on next
time. Upon power-on
3
is displayed, requiring all three password keys to be entered
to unlock the display. To change the password, see “Changing the Keyless Password” on
Page 3-14.
If the Dim Timer is not “off,” and the keyless password is not “off” when the Dim Timer
expires, the display station locks. Pressing the space bar once and entering the password
“unlocks” the display.
