The Mode Display
This display will depend on the current laser lock mode. The bottom right displays the lock status (OFF,
Locking, Locked). The bottom left remains clear or displays an error message if present (see Section
5.4 for error details).
Press ENTER to either enable or disable the laser. Enabling the laser changes the locking status from
OFF to Locking (then Locked). Disabling the laser changes the locking status from Locked (or Locking)
to OFF. Additionally, a green LED illuminates when the laser is enabled. The LED is underneath the
connector for output fiber.
Pressing MENU brings user to the Mode Settings display EXCEPT when laser is in Channel Frequency
Lock Mode and locked. In this case, the user is able to update the offset without forcing a new calibration
sequence. See Section 5.2.3.4 for more information.
