Horizontal Scan and manual determination

Direction Finding (Horizontal Scan: On)

Once the bearing is displayed on the polar diagram, you can also specify 

the bearing manually. This may be necessary if the calculated result does 

not appear to be sensible due to interference.

To set the bearing manually:

You have made a Horizontal Scan.

The red (lower) arrow indicates the calculated bearing. The green 

(upper) arrow indicates the direction in which the antenna is pointing.

1.

Point the antenna in the desired direction and press the 

Manual Correct. of Direction

 softkey.

The red arrow moves to the manually specified direction (green 

arrow) when you press the softkey. 

2.

Press the 

SAVE

 key on the Basic Unit to save the measurement results.

A window shows the save process.
