1 Drag the [Gain] (reception gain adjustment) slider dial in Radar signal information,
turn the trackball, and set up reception gain.
Moving the slider to the right increases gain.
Moving the slider to the left decreases gain.
The current reception gain level is indicated by the bar and a numeric value.
[Points on adjustments]
As reception gain is increased, the range in which radar images can be observed widens; however, if
gain is increased too high, receiver noise, false echoes and other undesired signals will increase on
the screen, lowering the visibility of targets.
Also, it gets easier to see the screen display if gain is decreased to observe cluttered targets and close
range, but be careful not to overlook small targets.
Memo
If the optimal setting value was lost, it is recommended to reset to
the initial value and tune up again.
The initial setting value is indicated as shown in the figure at right.
