To access the main menu, press MENU|MENU. Gain This is used to adjust the sensitivity of the receiver. Setting Gain to a low level will clear up some of the clutter on the screen, but also could eliminate some desired echoes. A high level of the Gain, allows you to see greater detail around you, but will clutter the screen. NOTE: When adjusting Gain back to a useable level, increase the level until you see a light peppering of echoes on the display. Also remember, you will have to adjust gain every time you change ranges. To adjust Gain: 1. Press EXIT to remove the scrollbar from the screen. 19 Gain vertical scrollbar (left) with Anti-Sea Clutter scrollbar (right). Anti-Sea Clutter (STC): This lowers receiver sensitivity at shorter ranges to reduce or eliminate echoes that reflect back at the antenna due to wave action close to the vessel. Caution Increasing STC may reduce or eliminate weak echoes, like small vessels. Use only the minimum amount needed, then check back periodically to see if the STC level may be decreased. To adjust Anti-Sea Clutter: 1. Anti Rain Clutter (FTC) This is used to reduce or eliminate massive numbers of small echoes that clutter the display during rain or snow storms. To adjust Anti-Rain Clutter: 1. The Anti-Sea Clutter vertical scrollbar will appear. WARNING: Increasing FTC may reduce or eliminate weak echoes, like those from small vessels. Use only the minimum amount needed, then check back periodically to see if the FTC level may be decreased. 20 Anti-Rain Clutter vertical scrollbar (left) with Interference Rejection scrollbar (right). Interference Rejection This feature filters out signals from other radars close to your location. To adjust Interference Rejection: 1. Use to adjust the Interference Rejection setting to a desired level. Radar Range This feature allows you to expand the area shown on the display unit, which is helpful when you want to see targets a great distance from you. You also can decrease the range to focus on targets closing in on you. NOTE: When switching radar ranges, you likely will need to adjust Gain, STC and FTC settings to achieve optimum performance. To adjust radar range: 1. Select RADAR RANGE from the radar menu and press ENT, which will launch the radar range list. The range you chose is now in use on the radar display. Tip: Once you are comfortable with the various radar range options, you can more easily switch ranges by pressing the ZIN or ZOUT keys. Radar Echo Expansion This feature will make weak signals more visible on the display by lengthening radar echoes.
