WARNING! The electronic parts in the Remote Sonar Sensor (RSS) are made to withstand use when casting into water. Because shock from
abrupt contact with rocks can damage your RSS, we do NOT recommend using your RSS in water that is less than one foot (0.3 m) deep.
Operational Modes
The RSS can be used in two distinct ways:
Sonar Graph: The RSS can be used to create a sonar graph of the bottom. Cast the RSS into the water beyond an area of
interest, then reel in the RSS at a slow and steady rate The digital display will provide precise information for bottom con-
tour, depth and structure below the RSS. Fish and bait fish will be displayed when detected.
Stationary Float: The RSS can be used as a float in a stationary location to monitor the area below, giving you a live
update as fish approach your bait.
Activating the Rod Mounted Display Battery
When you first use the RF20 SmartCast Rod Mounted Display you will
need to activate the display battery. Use a coin to remove the battery
door on the back of the Rod Mounted Display, then remove the plastic
strip located in the battery compartment.
Make sure that the O-ring in the battery compartment is present, positioned correctly in the grooves, and free of debris
before re-installing the battery door.
NOTE: Replace the Rod Mounted Display battery only with a 2450 CR-type battery. These batteries can be purchased from most electronics
retailers.
NOTE: Under normal use you should expect the life of the display battery to last up to 40 hours of operation. Operation in cold weather will
significantly reduce the life of the battery.
Attaching the Rod Mount Display
1. Determine which of the three Sleeves will fit onto your rod. Each
Sleeve will fit a variety of rod sizes, but Sleeve A fits rods closest to
¹₂
" diameter, B fits rods closest to
⁷₁₆
" diameter, while C fits rods
closest to
³₈
" diameter.
2. Once you have selected a specific Sleeve, attach it to the Rod Mounted Display, then slip the assembled unit onto
your rod and tighten the straps. Make sure that the letter on the Sleeve is visible once the unit is mounted on the
rod, so that the Rod Mounted Display and the Sleeve are both on the top side of the rod when you are fishing.
NOTE: You should remove the RF20 from your rod and store it when you are not actively using it. See Maintenance for important storage
information.
NOTE: Keep the unused Sleeves in case you get a rod of a different size. If you need a replacement Sleeve, you may order it from our
website, www.humminbird.com, or from participating retailers and dealers.
