repetition rate Press the RANGEEchoose the range The range and range ring interval appear at the top left corner on the screen Range of range and range ring interval indications 17 Receiver Sensitivity The GAIof the receiver It works in precisely the same manner as the volume control of a broadcast receiver amplifying the signals received To set the sensitivity you first choose the automatic sensitivity setting which best matches current sea condition Then if necessary you may fine tune the sensitivity manually The proper setting is such that the background noise is just visible on the screen If you set up for too little sensitivity weak echoes may be missed On the other hand excessive sensitivity yields too much background noise weak targets may be missed because of the poor contrast between desired echoes and the background noise on the display 1 Press the GAIthe display shown below appears AUTO MODERATEGain adjustment window 1 OPERATION 2 Press or to choose AUTO or MANU as appropriate Automatic gain adjustment1 Press to open the automatic gain options window gain options 2 Press or to choose ROUGH MODERATE or CALM depending on sea conditions 3 Press to close the window Manual gain observing the screen and the gain tuning bar press or to adjust the gain The setting range is 0100 3 Press the MENUESC18 Suppressing Sea Clutter In rough weather returns from the sea surface called sea clutter are received over several miles around own ship and mask nearby targets This situation can be improved by properly suppressing the sea clutter with the AC SEA control To set the AC SEA you first choose the automatic AC SEA setting which best matches current sea conditions Then if necessary you may fine tune the AC SEA manually In most cases suppress the clutter until it has disappeared to leeward but a little is still visible windward If the setting is too low targets will be hidden in the clutter while if it is set too high both sea clutter and targets will disappear from the display A common mistake is too oversuppress sea clutter so that it is completely removed You can see how dangerous this can be by setting up for maximum AC SEA A dark zone will be created near the center of the screen causing a loss of closein targets This dark zone is even more dangerous if the sensitivity has not been properly adjusted Always leave a little sea clutter visible on the screen first adjusting automatically and then fine tuning with the manual control as necessary Sea clutter at screen center 1 Press the GAIthe display shown below appears AUTO
