User manual HUMMINBIRD RF20 Operations Manual

[. . . ] Your Humminbird® is designed for trouble-free use in even the harshest marine environment. In the unlikely event that your Humminbird® does require repairs, we offer an exclusive Service Policy-free of charge during the first six months after purchase, and available at a reasonable rate after the six month period. For complete details, see the warranty information at the end of this manual. We encourage you to read this operations manual carefully in order to get the full benefit from all the features and applications of your Humminbird® product. [. . . ] NOTE: Menu settings are not saved in memory. All settings return to factory defaults when the SmartCast is turned off. Select a higher number to show weaker sonar returns on the display, or a lower number to remove clutter from the display. Adjusting Sensitivity also affects how sonar returns are identified as Fish ID Symbols - more fish will be detected at the highest setting of 5, fewer at the lowest setting of 1. When in automatic, the lower range will be adjusted by the unit to follow the bottom. NOTE: In manual operation, if the water depth is greater than the depth range setting, the bottom will not be visible on the display. Depth scale changes or signal loss will cause lines with missing detail and/or abrupt changes in the graphed bottom. When the Depth Range is set to Auto, the depth is set to keep the bottom in the lower third of the screen. The screen image jump shown here is due to an automatic change in depth. New returns graphed at a different scale will not match up with the historic data already graphed at a higher or lower scale. Vertical lines can also occur as the radio signal from the RSS is lost and then regained in rough water conditions. Select Off for no fish alarm, or On for fish alarm. Fish ID must be set to On for Fish Alarm to work. Select either Off to view "raw" sonar returns, or On to view fish symbols. Fish ID uses advanced signal processing to interpret sonar returns and will display a Fish Symbol when very selective requirements are met. Fish Alarm does not sound if Fish ID is turned off. There are two versions of the RSS that are available at your local tackle dealer, major outdoor retailers, or at the site www. The Channel A RSS unit comes standard with the RF20. you also have the option to purchase additional Channel A or Channel B RSS units. When using the A or B version of the RSS, make sure to select the appropriate channel using the CHANNEL menu choice. This gives you the flexibility to use a different type of RSS than the one you are currently using if another angler is using a SmartCast product within 100 feet (30 meters) of your Rod Mounted Display. If you have a Channel B RSS, you will need to set the channel to B each time you power up the RF20. [. . . ] After the original warranty period, a standard flat rate service charge will be assessed for each repair (physical damage and missing parts are not included). Any repairs made after the original warranty will be warranted for an additional 90 days after service has been performed by our factory technicians.
