Case Assembly Overview
In the following step-by-step procedures the following portable case
assembly tasks are described, and must be performed in order:

1. Attaching the control head

2. Installing the batteries

Attaching the Control Head
1. Remove the thumb knob bolt, gimbal

knob, and rubber washers
from the hardware bags.

Thank you for purchasing a Smartcast wireless fishfinder
from Humminbird, America’s #1 Manufacturer of quality 
consumer marine electronics.

With this purchase you should have:
❏ Remote Sonar Sensor ❏ Smartcast Control Head ❏ Hardware
❑ Smartcast Portable base ❑ Smartcast Operation Guide

If any of these components are missing or are not included, please
contact our Customer Resource Center at 1-334-687-0503.

WARNING! The RSS (Remote Sonar Sensor) is not intended for use by children less
than 6 years old without adult supervision as the RSS may represent a choking hazard
to small children. 

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 recommend using this sensor in water 1 foot and deeper. 

Do not lay the RSS in a wet area when not in use as this will turn on the RSS and 
shorten its usable life.

The bottom of the RSS should not be handled during sonar operation.

2. Place the rubber washers between the control head’s pivot

knuckle and the arms from the portable case. Make sure that
the control head screen is facing the case cavity and away
from the battery compartment.

3. Slide the pivot bolt through the side with the smaller hole (

¹⁄₄

”)

and screw the gimbal knob onto it using only 2-3 turns. The
gimbal knob may have two alignment pins that will seat into
holes in the case arm holding the Smartcast control head.
Make sure these pins are seated and then tighten the assem-
bly to a snug tension.

Installing the Batteries in the Smartcast
1. With a #2 Phillips screwdriver, remove both screws located

on either side of the battery door.

2. Insert the 8 “AA” batteries (not included) into the case as

shown on the diagram inside the battery compartment.

3. Before reattaching the battery door, make sure the silicon

gasket is still in place. It should be just above the plastic, and
completely in the gasket channel. Make sure that the gasket
is clean of debris.

4. Reattach the battery door to the case using a #2 Phillips

screwdriver. Partially insert one screw and then the other.
Fully seat the screws. Hand tighten only; please do not use
power tools. Finally, plug in the power cable to the RF10.

5. Under normal use you should expect the life of the batteries

to last from 30 hours with the LCD backlight(s) on, to 80
hours with the backlight(s) off.

The line coming from your reel can be tied off to the front hole in
the RSS. If you wish to also 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 
factor for loss of 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.

The Remote Sonar Sensor (RSS) has a non-replaceable battery
that have a shelf life of three years and will last for approximately
400 hours of continuous use. Discard the used RSS in compli-
ance with local laws as you would any electronic components
and or batteries. The RSS uses a Lithium battery.

The Smartcast is a first-of-its-kind wireless fishfinder that is incred-
ibly easy to use. Simply attach the Remote Sonar Sensor (RSS) to the
end of your fishing line (see detailed attachment instructions) and
cast it into the water as you would with a normal float or lure. Then
power on the Smartcast Base display 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 display unit and plotted on the LCD
screen. New information appears on the right. As this information
moves to the left a very accurate picture of the underwater world is
created including depth of underwater objects such as the 
bottom, fish, and structures.

The RSS can be used in two distinct ways:

1. The RSS can be used to graph the bottom creating a sonar

graph. Cast the RSS into the water beyond an area of inter-
est. A slow and steady speed of reeling in the RSS will pro-
duce a screen detailing structure, fish and bottom detail.
Wave motion and rocking may have some effect, causing an
undulating bottom from the rhythmic wave action.

2. The RSS floats in a stationary location and monitors the area

below, giving you a live update as fish aprroach your bait.

To turn on the display, Press and release POWER-MENU. Press and
hold POWER-MENU until the display unit shuts down to power off.

The RSS has contacts that sense being in water. These contacts
turn on the Sonar Transmitter/Receiver and begin transmitting that
sonar information via radio to the display. The RSS automatically
stops using power when pulled out of the water.

At startup a intro screen will display followed by either
"Waiting for Sonar" or "Received Sonar". The Smartcast dis-
plays received underwater sonar 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. Reeling in the RSS at a slow
and steady rate will allow you to graph the bottom for structure,
detail and fish. Digital readouts provide precise information for
bottom contour, depth and fish locations below the RSS.

If you are using Smartcast to graph an area, terrain and bottom
composition variations are displayed on-screen. Fish and bait
fish are displayed when detected. Underwater conditions vary
greatly, so some experience and interpretation is needed to 
realize all the benefits of the Smartcast – use the picture below
as a guide to the most common conditions and practice using
the Smartcast over known bottom types.

Accessing Menu Features
A simple menu system accesses Smartcast base station’s
adjustable features. To activate the menu system, press the
POWER-MENU button and a menu appears. Press POWER-
MENU repeatedly to access other Smartcast menus one at a
time. When a menu is on the display, use the right and left arrow

keys to adjust the menu. Menus are automatically removed from
the screen after several seconds.

(Defaults to OFF)

Press POWER-MENU until the LIGHT
menu appears. Select either OFF or ON to activate the backlight .

(Defaults to 3)

Press POWER-MENU until the
SENSITIVITY menu appears.
Select a higher number to show smaller sonar returns on-screen,
or a lower number to remove clutter from the screen. Adjusting
Sensitivity also affects how sonar returns not attached to the bot-
tom are identified as Fish ID Symbols. Only large returns will be
shown as fish at a lower setting. Increasing Sensitivity selects
smaller returns to be identified as fish. Sensitivity settings range
from 1 at the extreme left to 5 on the right. Center is 3 and is the
Factory Setting.

(Defaults to AUTO)

Press POWER-MENU until the Depth
Range menu appears. Select AUTO to have the Smartcast auto-
matically set the Depth Range. Select 10,15, 20, 30, 60 or 100ft.
to set a manual depth range. This locks the depth range to a
specific setting.

5. The screen jumps and the bottom has an abrupt
change; sometimes a vertical line is missing or a
black line from top to bottom is displayed.

This screen image jump 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.

Replacement Battery Power Cables

You will not have to install the battery power cable before first use, but
may need to replace it should it become corroded after prolonged
usage in a marine environment. Order replacement cables at
www.humminbird.com.

Replacement / Optional RSS Units

There are two versions of the RSS that are available at your local tack-
le dealer, major outdoor retailers, or at www.humminbird.com.

The Channel A RSS (RF40A) comes standard with your Smartcast
product. The Channel B RSS (RF40B) is an optional RSS that will work
with your Smartcast unit (simply select Channel B in the Channel Menu
on the display unit) and will minimize RF Interference with Channel A
RSS units. If a Channel A and B are very close together, they could
experience sonar interference.

ensure there is no corrosion. Confirm that your batteries are good and
properly installed.

2. When in very shallow water, I get gaps in the bottom
reading and inconsistent digital depth indication.

The Smartcast will work reliably in water 2’ (.6m) or deeper. The
depth is measured from the RSS. A transmitter (RSS) to receiver
(Smartcast) distance of greater than 100' may cause intermittent
screen display. Overly rough water may cause the RSS to submerge,
again losing contact.

3. The screen begins to fade out. Images are not as
sharp as normal.

Check the battery voltage. The Smartcast will not operate on voltages
below 8 VDC. Use 1.5 volt alkaline “AA” batteries.

4. The display shows many black dots at high 
sensitivity settings.

You are seeing noise or interference caused by one of several sources.
Noise can be caused by other electronic devices. Turn off any nearby
electronics and see if the problem goes away. Other sonar devices or
any electronic device operating in the 915 mHz range could cause
interference with your Smartcast. Additionally, the Smartcast system
comes with the capability to receive separate signals from an A-type
RSS or a B-type RSS. Two A or B type RSS units used simultaneously
can cause RF interference between each other.

Do not attempt to repair the Smartcast or RSS yourself.There are no user
serviceable parts inside, and special tools and techniques are required
for assembly to ensure the waterproof integrity of the housings. Repairs
should be performed only by authorized Humminbird technicians.

Many requests for repair received by Humminbird involve units that do
not actually need repair. These units are returned “no problem found.” If
you have a problem with your Smartcast, use the following trou-
bleshooting guide before calling the Customer Resource Center or send-
ing your unit in for repair.

1. Nothing happens when I turn the Smartcast on.

Check the power cable connection at both ends. Check the power con-
nection to the Smartcast. It is possible to force the power cable con-
nector into the cable holder incorrectly. If the connector is reversed, the
unit will not work. Examine the contacts on the back of the unit to

(Defaults to A) 

Press POWER-MENU until the Channel menu appears. Select
either A or B to match your RSS. See Replacement / Optional
RSS Units.

Your Smartcast base is designed to provide years of trouble-free oper-
ation with virtually no maintenance. Follow these simple procedures to
ensure your Smartcast continues to deliver top performance.

If the unit comes into contact with salt spray, wipe the affected 
surfaces with a cloth dampened in fresh water. The RSS wet switch
pins must be rinsed with fresh water after exposure to salt water to
prevent corrosion. Do not use a chemical glass cleaner on the lens --
this may cause cracking in the lens.

When cleaning the LCD protective lens, use a chamois and 
non-abrasive, mild cleaner. Do not wipe while dirt or grease is on the
lens. Be careful to avoid scratching the lens.

If your RSS remains out of the water for a long period of time, it may
take some time to wet it when returned to the water. Small air bubbles
can cling to the surface of the RSS and interfere with proper operation.
These bubbles dissipate with time, or you can wipe the face of the RSS
with a gathered wet cloth.

Never leave the unit in a closed car or trunk - the extremely high tem-
peratures generated in hot weather can damage the electronics.

(Defaults to OFF) requires Fish ID ON.

Press POWER-MENU until the FISH ALARM menu appears. Select
OFF for no fish alarm, or one of the following symbols to set the
alarm point and turn it on.

• Alarms on big fish only.

• Alarms on big and medium fish only.

• Alarms on all fish.

(Defaults to ON)

Press POWER-MENU until the FISH ID menu appears. Select either
OFF to view “raw” sonar returns, or ON to take advantage of
Smartcast’s ability to identify sonar returns that are determined to
be a fish. The sensitivity setting also affects the definition of sonar
returns as fish (see Sensitivity). Some fish symbols will show the
depth of the fish above the fish symbol. Fish Alarm does not sound
if Fish ID+ is turned off.

(Defaults to ON)

Press POWER-MENU until the Bottom
Black menu appears. Select OFF to gain bottom hardness infor-
mation by viewing second returns. Leave your view setting on
Bottom Black for a high contrast, easy to view from a distance,

contact, causing gapped signal input. A low rod tip
or heavy line may cause signal loss if the RSS 
submerges.

Use a heavier test line for the RSS and your 
standard knots and tackle such as a swivel.

Handle the RSS by the antenna tower
when it has been in water.

*The second leader hole is for using the RSS as a 
float. Connect a lighter weigh hook line to this hole.
Do not over-weight the hook line as this will 
submerge the RSS, causing signal loss.
