Humminbird rf25 Guida Al Funzionamento

When you first use the RF25 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.

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.

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.

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.

Use a heavy test line, standard
knots, and tackle such as a swivel.

Handle the 

RSS

TM

by the antenna tower

when it has been in water.

The second leader hole is for using the RSS

TM

as a

float. Connect a lighter weight hook line to this hole.
Do not over-weight the hook line as this will
submerge the RSS

TM

, causing signal loss.

Rod Mounted Display

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.

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

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.

See the procedures that follow for specific instructions
on turning the light on or off or changing the channel
from A to B.

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).

Temperature of 40
Means LED is OFF

Temperature Setting of 45

Means LED is On

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 Rod Mounted
Display. The RSS™ automatically stops using power a few
seconds after being pulled out of the water.

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.

If you have just

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. (0 -10, Default = 5)

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)  

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.

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)

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)

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)

Press the POWER-MENU button
until  CONTRAST appears. Select a setting from 
1 through 10. (1 to 10, Default = 5)

Your SmartCast

The SmartCast

®

is a first-

of-its-kind wireless fish-
finder that is incredibly
easy to use. Simply attach
the Rod Mounted Display
to your rod, then 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

®

RF25 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 RF25 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.

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.

To scan an area,

cast and then reel

in at a slow, steady

rate with your rod

tip up.
