Display Unit
The LCD display unit is waterproof to CFR46 and can be installed either
above or below deck.
The unit includes:
• 7" monochromeLCD display
• Trackpad
• Eleven dedicated (labeled) control keys
• Four soft keys (unlabeled) whose functionality changes
®
• The SL72RC PLUS includes two slots for the C-MAP NT chart cards
The display and keys can be illuminated for night-time use.
Full functionality of the radar or radar/chartplotter is achieved when it is part
of an integrated system, with other equipment connected via SeaTalk or
NMEA 0183. Data from this equipment including position and heading is
displayed on the display and is used in calculations. Details on connecting
other equipment are given in Chapter 8.
Scanner
The SL72 PLUS and SL72RC PLUS are supplied with an 18", 2 kW (2D)
scanner unit which illuminates targets with microwave energy and then
collects the returns from those targets. The scanner includes a sensitive low-
noise front end receiver, and a variety of clutter attenuation controls to
maintain target resolution.
The scanner is adjusted and operated from the display unit. It can be switched
between transmit and standby modes. The scanner also has a power-saving
timed transmit mode which pauses between bursts of transmissions.
