[Page 1] [1] MODE (Mode) 
 
・  Selects the function name to be indicated at the lower left of the radar display when the function is 
selected. 
・  When the setting is changed back to the factory setting, the initial value of the selected mode is called. 
・  The following 9 modes are provided: 
 
  Coast    : Use this mode to monitor a relatively short range, for example, bays and 
      coasts where many boats and ships are running. (Importance is attached to 
   resolution.) 
  Deepsea    : Use this mode to monitor a relatively long range, for example, the open sea. 
      (Importance is attached to long-range gain.) 
  Fishnet    : Use this mode to detect small targets such as fishnets of round haul netters 
      hidden by sea clutter returns. (Importance is attached to sea clutter 
      suppression, and gain to moving targets lowers.) 
  Storm    : Use this mode when many rain / snow clutter returns or sea clutter returns 
      are detected in stormy weather. (Importance is attached to rain / snow 
      clutter and sea clutter suppression, and gain slightly lowers.) 
  Calm    : Use this mode when only a few rain / snow clutter returns or sea clutter 
   returns are detected. 
  Rain     : Use this mode when sea clutter is not strong but rain / snow clutter is 
      strong. (Importance is attached to rain / snow clutter suppression, and 
      gain slightly lowers.) 
  Long    : Use this mode to monitor utmost distances in the broad ocean. 
  User1    : General mode used when the nine modes above are not applicable. 
  User2    : General mode used when the nine modes above are not applicable.
