WARNING! Disassembly and repair of this electronic unit should
only be performed by authorized service personnel.
Any
modification of the serial number or attempt to repair the original
equipment or accessories by unauthorized individuals will void the
warranty.
Handling and/or opening this unit may result in
exposure to lead, in the form of solder.
WARNING! This product contains lead, a chemical known to the
state of California to cause cancer, birth defects and other
reproductive harm.
WARNING! The bottom of the RSS™ should not be handled
during sonar operation, as this may cause physical discomfort
and may result in personal injury in the form of tissue damage.
Handle the RSS™ only by the antenna tower when it has been
in the water.
WARNING! The RSS™ (Remote Sonar Sensor) is not intended
for use by children younger than 6 years old without adult
supervision as the RSS™ may represent a choking hazard to
small children.
Using the SmartCast ®
The SmartCast ® is a first-
of-its-kind wireless fish-
finder that is incredibly
easy to use. Simply
attach the Remote Sonar
Sensor (RSS™) to the
end of your fishing line
and cast it into the water
as you would a normal
float or lure. Then power
on the SmartCast ® RF35 and you are ready to fish. The
SmartCast ® system uses sonar technology to send sound
waves from the RSS™ into the water. The returned
“echoes” are transmitted with wireless technology to the
RF35 and plotted on the display. New information appears
on the right. As this information moves to the left a very
accurate picture of the underwater world is created,
including objects such as the bottom, fish, and structures,
as well as the depth of the bottom.
NOTE: The RF35 display is designed to be used with polarized
sunglasses only when the user is looking straight at the screen.
You may not be able to read the display from other angles when
wearing polarized sunglasses.
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 contour, 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 Wrist Mounted Display
Battery
When you first use the RF35 SmartCast ® Wrist Mounted
Display you will need to activate the display battery. Use a
coin to remove the battery door on the back of the Wrist
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 Wrist 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.
NOTE: Your RF35 will start up in Watch mode after the battery is
installed initially. See Powering the Display ON and OFF and
Watch Mode for more information.
Attaching the RSS™
The line coming from your reel can be tied off to the front
hole in the Remote Sonar Sensor (RSS™). If you also wish
to use the RSS™ as a conventional float, use the second
hole to attach your hook using a lighter weight line. A snag
will break the lighter line if you have to break free. Slip line
techniques are not recommended because of the higher
risk of losing the RSS™. If you do use the slip line
method, use a lighter weight line after the lower stop,
enabling retrieval of the RSS™ if the lower line with hook
breaks away.
CAUTION: You will increase the possibility of breaking your line if
you use light test pound line on your reel. The RSS™ is positively
buoyant (is buoyant under its own weight plus 0.2 ounces or 5.7
g of bait and lead weight.) The maximum amount of weight for
any attachment to the RSS™ is approximately
¹²₆₄ to ¹³₆₄ ounces
(5.3 g to 5.8 g), and includes the combined weight of any hook,
line, weight, swivel/snap swivel and bait that is attached to the
RSS™. The RSS™ itself weighs 1 ounce (28 g), and therefore
light test line might break.
NOTE: Store the RSS™ in a dry, non-metallic container, such as
a tackle box, in a separate compartment, and isolated from any
metallic devices.
RSS Power
The Remote Sonar Sensor (RSS™) has a separate, non-
replaceable lithium battery that has a shelf life of three
years and will last for approximately 500 hours of in-water
use (when the nighttime LED is turned off). Discard the
used RSS in compliance with local laws as you would any
electronic component or battery.
The RSS™ will turn on its Sonar Transmitter/Receiver
automatically when it is immersed in the water. Once
immersed, the RSS™ will begin transmitting the sonar
information via radio frequency (RF) to the Wrist Mounted
Display. The RSS™ automatically stops using power a few
seconds after being pulled out of the water.
WARNING! Do not place the RSS™ in a wet area when not in
use as this will turn on the RSS™ and shorten its usable life. Store
the RSS™ in a dry area when not in use to conserve power.
Never place the RSS™ in a wet area of a boat or on a metal
surface that could accidentally power it on.
NOTE: If the RSS™ was used in salt water, rinse it with fresh
water before storing it.
What’s On the
Display
The SmartCast ® displays
underwater information in an
easy-to-understand format.
The top of the display
corresponds to the water
surface, and the bottom of
the display corresponds to
the selected Depth Range (see Depth Range). The display
varies as the area under the RSS™ changes.
Underwater conditions vary greatly, so some experience
and interpretation is needed to realize all the benefits of the
SmartCast
® – use the diagram as a guide to the most
common conditions and practice using the SmartCast ®
over known bottom types.
The SmartCast ® can also display the time and date.
Press the RIGHT Cursor button to momentarily view the
time and date.

automatically removed from the display after several
seconds.
Sensitivity
Press the POWER-MENU button
until SENSITIVITY appears. 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 10,
fewer at the lowest setting of 0. (1 - 10, Default = 5)
Depth Range
Press the POWER-MENU button
until DEPTH RANGE appears. Auto is the default setting.
When in automatic, the lower range will be adjusted by the
unit to follow the bottom. Selecting a manual depth range
locks it to the setting you select. (Auto, 10, 15, 20, 30, 60
or 120 feet [3, 5, 6, 10, 20, or 40 meters], Default = Auto)
NOTE: In manual operation, if the water depth is greater than the
depth range setting, the bottom will not be visible on the display.
Select Auto to return to automatic operation.
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.
Fish Alarm
Press the POWER-MENU button
until FISH ALARM appears. Select Off for no fish alarm, or
On for fish alarm. Fish ID must be set to On for Fish Alarm
to work. (Off,On, Default = Off)
Fish ID
Press the POWER-MENU button
until FISH ID appears. 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. (On, Off, Default = On)
Channel
Press the POWER-MENU
button until CHANNEL appears. Select either A or B to
match your RSS™. See Channel A and B RSS™
Units. (A, B, Default = A)
Contrast
Press the POWER-MENU button
until CONTRAST appears. Select a setting from 1 through
10. (1 to 10, Default = 5)
Channel A and B RSS Units
Your SmartCast ® unit comes with an Advanced RSS. This
Advanced RSS may be programmed to either Channel A or
Channel B. This A/B Channel option gives you the flexibility
to switch to a different channel if another angler is using a
SmartCast
® unit within 150 feet of your RSS to reduce
possible interference. See Changing the Channel on
the Advanced RSS for details on selecting either Channel
A or Channel B.
NOTE: RSS units, regardless of channel, may generate erratic
depth readings as a result of sonar interference when used in
close proximity (closer than 40 feet) to each other or to other
sonar devices.
Understanding the Advanced RSS
The Advanced RSS provides the following functionality:
• Water Surface Temperature
• Blinking Light for nighttime use
• A/B Channel Select.
Water temperature will be displayed automatically on the
screen.
You must manually program the Advanced RSS in order to
turn the light on or off or to change the RSS channel
setting to A or B.
Default settings on new products are Light = OFF and
Channel = A.
RSS Programming Mode
You may change the light setting or the channel type on
the Advanced RSS using a programming mode that is
accessed by touching the wet switch contacts on the
bottom of the RSS.
NOTE: Please read this and the next section BEFORE you try to
program the Advanced RSS using the wet switch contacts.
Specific step-by-step procedures to turn on the light and to
change the channel follow this section. You will find it easier to
perform these steps once you have grasped the way the
programming mode works.
The programming mode allows you to:
• turn on the blinking light
• switch the Advanced RSS Channel from A to B.
The SmartCast ® Control Head temperature readout provides
user feedback to help you make the correct selections. The
temperature readout will change on the Control Head to
40°F (4°C), 45°F (7°C), 50°F (9°C) or 55°F (12°C) to
signify the following settings.
NOTE: If the temperature readout is set for degrees Celsius then
the temperature readout will change on the Control Head to
4,7,9 or 12 to signify the following settings.:
Light setting:
Temp changes to… Means that…
40°F (4°C) Blinking light is OFF (factory default)
45°F (7°C) Blinking light is ON (but only blinks
when the Advanced RSS is in the
water)
Channel setting:
Temp changes to… Means that…
50°F (9°C) RSS is set to CHANNEL A (factory
default)
55°F (12°C) RSS is set to CHANNEL B
IMPORTANT: The SmartCast ® Control Head must be turned on
and the CHANNEL SELECT SetUp menu on the Control Head
must be set to Channel A (even if the RSS is set to Channel B)
before you can see the feedback on the Control Head
temperature readout.
NOTE: The Advanced RSS programming mode will time out
after 20 seconds of no user activity, display the Start-Up screen,
and return the RSS to normal operation.
NOTE: If the temperature display returns to a normal reading, or
the Start-Up screen appears on the display, you are no longer in
programming mode.
How the Wet Switch™ Works
In the following sections, you will use the wet switch
contacts on the bottom of the Advanced RSS to enter
programming mode and to change the Light and Channel
settings. Before you try these procedures for the first time,
please read through this section to familiarize yourself with
the way the Wet Switch™ works.
Your finger should be moist, but not dripping, before you
touch the Wet Switch™. You can achieve the correct
dampness by dipping your finger in water, then dabbing
your finger twice on a towel.
A “touch” means touching both wet switch contacts at the
same time with your moistened finger, using medium
pressure. The time between touches needs to be one
second or less.
NOTE: Your finger must make contact with both of the wet switch
pins simultaneously in order to tap them successfully.
See the procedures that follow for specific instructions
on turning the light on or off or changing the channel
from A to B.
Turning on the Advanced RSS
Blinking Light
To turn on the blinking nighttime fishing light:
1. Wet your finger and tap the wet switch on the
Advanced RSS three times (the time between
touches needs to be one second or less) to enter
the Light programming mode. The temperature
reading on the Control Head will change to show
a temperature reading of 40°F (4°C) (blinking
light OFF).
