sonnel observing the regulations for electrostatic sensitive devices.
4.3 Functional Check
If the green LED above the toggle switch does not light up when you activate the LNA,
there is a potential problem with the connection to the R&S

In order to verify the connection:
●
check the control cable connector
●
check the settings of the R&S FSH4/8.

The R&S HL300 should only be stored and transported in the supplied transport bag.
Make sure that the RF and control cable is bent towards the front of the antenna. Attach
the R&S

allowed bending radius of the cable (see
​
figure 4-1 and
​
