AGC suppresses the echo tail of strong targets, e.g., the
seabed, for easy recognition of fish schools adjacent to the sea
bottom. Position "1" or "2" is the normal setting.
NOISE LIM is used to reject noise which is displayed over the
screen in light blue. Position "3" is the normal setting.
VP (Video Processor) adjusts the after-image of the echoes for
proper period; echoes are stretched in the radial direction. Set
at "1" for ordinary use.
IR (Interference Rejector) rejects random noise and
interference caused by other echo sounders or sonars.
BRILL adjusts brightness of the screen in eleven steps.
CONTRAST adjusts the range of brightness between
highlights and shadows on the produced image.
DIMMER adjusts panel (main panel and control box panel)
illumination.
AUDIO controls the volume of the built-in loudspeaker for
monitoring a target echo appearing the bearing mark.
POWER switches on and off the entire system.
