INSTRUCTION MANUA
z [GAIN] Control
Turning the [GAIN] control clockwise increases receiving sensitivity and extends the
radar observation range. If the sensitivity is too high, the receiver noise increases
reducing the contrast between the targets and the background video. As a result, the
targets become obscure on the radar display. To observe densely crowded targets or
short-range targets, turn the [GAIN] control counterclockwise to reduce the sensitivity so
that the targets are easy to observe. However, be careful not to overlook important small
targets.
Switching to Manual/Automatic Mode
1 Hold down the [GAIN] control.
The sensitivity can be switched between manual and automatic modes.
The mode is indicated as shown below.
