Turning on the Unit
Before turning on the FLS-2600B, please read the Safety Information on
page 7.
To turn the unit on and off, use the red button in the lower left-hand corner
of the front panel. The source is not active upon startup. To activate it, see
Activating/Deactivating Light Emission on page 42.
Upon startup, the unit beeps twice, performs a self-test, and then enters the
main menu with the same settings that were active when it was shut
down. When the unit is turned off, the following items remain in a storage
device called non-volatile memory:
 current power setting
 current wavelength setting
 current mode (normal/high resolution)
 current display mode (wavelength/power)
 current Setup menu settings
 shortlisted wavelengths (up to 100)
 sweep parameters
 saved sweep configurations (up to five)
Note: The power cord is the most effective disconnecting device. To ensure that
the unit is completely turned off, disconnect the power cord.
