3.3.6 Adjusting the tuning Please refer to "3.1.2 Tuning operation". 3.3.7 Adjusting the sensitivity Attention • Please ensure that the sensitivity adjustment is made to an optimal level when undertaking monitoring. • If the sensitivity is too low, hazardous objects, ships and other floating objects may not be displayed. • If the sensitivity is too high, receiver noise at the PPI screen will increase and this may impair monitoring. (a) Turn the [Gain] control. ・When the control is turned in the counterclockwise direction, the sensitivity decreases and when the control is turned in the clockwise direction, the sensitivity increases. ・In general, optimal adjustment of sensitivity is as follows. The image size of the echo from the intended target is maximized. It does not come into contact with echoes from other targets. The image of the echo is small as the sensitivity is too low. The sensitivity has been adjusted to an optimal level. Images overlap as the sensitivity is too high. 171
