Noise filter
noise filter is used to filter the noise from the air or water
environment to get a clear sonar image on the screen.
In many situations, your fish finder display will be
affected by undesired signal which may be caused by
your boat engine, turbulence, wiring, or other electrical
and mechanical sources. Such undesired signal will
produce unwanted mark on the screen, which may cause
a misunderstanding of the underwater condition.
In such situations when you see too much clutter on the
screen, increasing the noise filter will play an effect. The
larger the value is the more unexpected sonar returns
will not be displayed.
• Trouble shooting
In the event of problem during product use, we invite you to read the following trouble shooting part carefully
before you send the product for maintenance.
No signal screen
In the fish finder fails to receive signals from the sen-
sor, it will stop updating the screen (which will then
remain unchanged).
under any circumstances, if the sonar unit cannot re-
ceive signals transmitted by the ReS sensor the screen
will seem the same until signals are restored.
- ALF100 is a product depending upon line of sight.
obstacles between the handheld and the sensor can
contribute to signal loss.
- ALF100 has a detection depth ranging from 0.6 to
30 meters. Incorrect readings may appear in water
areas with depth less than 0.6m. Additionally, consi-
dering the sonar physical characters, we suggest you
avoid using the product in shallow or small-sized en-
closed water areas.
note: The depth is calculated from the bottom of sen-
sor, which is fixed on your bait boat.
- The maximum remote-control distance for sensor
reaches 1000 feet (300). If the sensor with the bait
boat moves out of the range, inconsistent signal will
happen or even no signals will be transmitted to the
sonar unit.
Nothing is displayed after the fish finder is
powered.
Be sure the battery's positive and negative poles are
correctly oriented in the holder. Also, check if the bat-
tery has enough capacity.
When using the device in shallow water areas, the
screen does not display things normally and depths
are not indicated with consistency.
ALF100 has a depth capability from 0.6 to 30m, howe-
ver due to the sonar character, the sensor cannot
achieve the best performance in shallow water.
Generally speaking, please use ALF100 in water area
not shallow than 1m.
If the noise filter is increased too high, most sonar returns
(which maybe fish) will not be displayed.
In situation while water is clear, try decreasing the noise
filter, however in situation while water is turbid, try
increasing the noise filter will be helpful.
When the water is deep enough, the high value setting
may greatly affect or even hinder your fish finder's
performance to find the bottom. So, in deep water,
decreasing the noise filter value will be helpful.
note: In some situations while you have big trouble
with noise, try finding and fixing the interference source,
rather than operating your fish finder with a very high
noise filter value.
The picture displayed on the screen vibrates.
The picture vibrates because the sea bottom depth
being scanned is changing. Since the depth range
used by the current test signal and by the previous
test signal differs, plus the varying height of water
bottom, pictures displayed on the screen will occupy
different heights, causing the vibrating phenomenon.
Nothing appears on the display even you can see
fish under the sensor.
- oil, dirt and fuel might cause a film to form on the
sensor and reduce its effectiveness. cleaning the
surface of the transducer might help.
- electrical noise nearby can interfere with the sonar,
which will cause some weaker signals being elimina-
ted.
The display become so cluttered that you even
could not achieve a clear bottom.
Such cluttered display maybe caused because:
- The water is too low
- The water is too turbid
- There is so much debris in the water
The sonar unit cannot reach 300m. There is a abnor-
mal display on the display, and when the bait boat is
about 60/70m faraway, the sonar unit stop working.
- Please confirm the sensor is mounted at the proper
location on your bait boat. An improper mounting
location will cause abnormal display.
- Please, check the ReS sensor installation, and confirm
the antenna mounted on your bait boat is correctly
connected to the control box through the antenna-
extended cable.
- The radio performance is easily affected by cloudy
or rainy day, which will cause the remote control dis-
tance decreasing greatly.
