PRR LEVEL

Changes pulse repetition rate. Normally, the highest rate (20) is used. When in shallow waters

second reflection echoes may appear between surface and actual bottom echo. In this case

lower the PRR level.

The choice “S” means the ship’s speed dependent mode, where the PRR changes

automatically with ship’s speed. (Requires ship’s speed input.) For further information about the

ship’s speed dependent mode, see page 1-20.

STC (High and Low Frequencies)

Adjusts STC level for the high and low frequencies, and is useful for suppressing surface noise.

The setting range is 0-10; the higher the setting the greater the extent of suppression. Setting

10 suppresses noise up to about 5 m. Turn off the STC when there is no noise on the screen,

otherwise weak echoes may be missed.

GAIN ADJ (High and Low Frequencies)

Adjusts gain (range: -50 to +50) of transceiver unit selected. Adjust the setting when the GAIN

control cannot effectively adjust the gain.
