The HSBSeriesLCDdisplayunitiswaterprooftoCFR46andcanbeinstalled
eitherabove or belowdeck.
Theunitincludes:
• 7" color (L760) ormonochrome (L755) LCD display
• Trackpad
• Elevendedicated(labeled) controlkeys
• Foursoftkeys (unlabeled)whose functionality changes
• Two slots for the C-MAP NT

chartcards
Thedisplayand keyscanbe illuminatedfor night-time use.
TheHSB (High Speed Bus)connection enables transferofdata between two
compatible units. For example,thefishfinder data is transferred from the
fishfinder(the master display)via the HSB connection and can be displayed
and controlledon any other HSBSeriesLCDorCRTdisplay (therepeater
display).Inparticular,youcanconnectyourHSB Series Fishfinderto a
remoteHSB SeriesPathfinderRadar to provide fishfinder, chart, and radar
functionality onbothdisplays.
Note:Your HSB Series display mayrequire a software upgrade torepeat
Fishfinder data. Please contact your authorized Raytheon dealer for details.

directly below the transducer. TheA-scopewindow also displays the pat-
ented BottomCoveragewidth indication.
• Zoom–enlargesallorpartof thebottomgraphdisplay. You canselectx2,
x4 orx6 magnification and the zoom area can be automatically ormanu-
allyadjusted.
Youcan select Zoom,Bottom Lock or A-scope to bevertically split withthe

inplaceofthebottomgraphdisplay.
If you choose dual frequency, thescrolling bottom graph is displayed in both
frequencies,splithorizontally.Zoom, Bottom Lock orA-scopecan be
displayed with the dual frequency graph.
All ofthese options are availablewhen the fishfinder is displayed in ahalf-
screenwindow.
