rear panel, it is in standby mode and the yellow LED [2] comes on. If you
press the ON/STANDBY switch [1], the instrument is switched on and the
green LED [2] comes on.
STANDBY operating state

Only properly qualified technicians are allowed to repair the R&S FS300. The
instrument does not contain any parts the operator can repair.
After the R&S FS300 has been switched on (Ê 3-36), the green LED ON [2]
on the instrument's front panel comes on. During booting, the "R&S SmartIn-
struments" symbol appears on a blue screen background [13]. Booting the
R&S FS300 takes approx. 1.5 minute and is completed when the measure-
ment mask (Ê 5-44) and the trace appear.
If the measurement mask (Ê 5-44) does not appear and the red or the red or
green LED flash alternately, switch the R&S FS300 off and on. In case the
error continues, return the instrument to our service center for checking.
If the instrument shows an error message after booting, then follow the
instructions in the chapter "Error messages" (Ê 9-167).
If the measurement trace does not appear on the screen shortly after booting,
the sweep time may have been too long. In this case, reset the R&S FS300 by
means of PRESET (Ê 6-140). If the trace still fails to appear, an error oc-
curred and our service center must check the instrument.
