Radar modes Use modes are available with preset control settings for different environments. Not all modes are available for all radar models. Custom mode All radar controls can be adjusted and will be retained after a mode change or radar power cycle. Radar defaults are set for general purpose use. Harbor mode The radar settings are optimized for areas such as busy waterways and large man-made structures where good target discrimination and rapid image updates are needed. Offshore mode The radar settings are optimized for offshore sea conditions and making isolated targets larger and easy to see. Weather mode The radar settings are optimized for best detection and presentation of rain clutter. Image update rate is slowed and color depth is increased. Bird mode The radar settings are optimized for best detection of birds. The radar is set up for maximum sensitivity. This mode is not recommended for use in congested harbor environments. Available controls for the various use modes Not all controls are adjustable in each mode. The following table shows preset controls and adjust-ability for each control.

Medium Off Off Off High High Off Off Modes in dual ranges When connected to a radar with dual range capability, it is possible to run the radar in Dual Range mode. Modes can be set independently for each range. For example, you can have Offshore mode for range A and Weather mode for range B. However, interaction between ranges occurs in some cases: • When using Bird mode for both ranges, maximum range is restricted to 24 NM and range resolution is reduced. • Fast scan - The antenna rotation speed is set to the slower of the two modes selected. For example, Fast Scan is disabled when using Harbor and Weather modes because Fast Scan is Off in Weather mode. • The Interference reject setting can affect the interference seen or removed on both ranges. Directional clutter rejection This mode is active when Sea clutter is set to Auto or Harbor/Offshore (options are dependent on the radar model). The gain of the radar receiver is adjusted dynamically during 6 ADDENDUM | Zeus Series
