Understanding the Screen

This chart shows all the information that your FC500 fish finder displays during the operatton. The
sonar information will firstly appear on the right hand side and then will scroll across the screen
from right to left. So what you see on the screen (fish symbols, fish arches, bottom shape etc) is
formed by the sonar history.

Keybard Instruction

The FC500 fish finder will make a noise when you press the key to indicate the unit has accepted a
command.

Power and Exit Key

The Power and Exit key is used to turn the FC500 fish finder on or off. It is also used to exit a
menu setting.

Menu Key

The Menu Key is used to enter into a menu setting and switch between the menus.

Ent Key

The Ent key is used to confirm a setting.

Up Arrow Key

The Up key is used to select a certain option on a menu.

In some menu options the Up arrow key is mostly used to increase the value, such as:
Sensitivity value, noise reject value, depth, alarm value etc.

Down arrow key

The Down arrow key is used to select a certain option on a menu. In some menu options, the
Down arrow key is mostly used to decrease the value, such as:
Sensitivity value, noise reject value, depth alarm value, etc.

Sonar

Sensitive

Sensitive determines how echoes will be displayed on the screen.
Increasing the sensitivity will enable you to see more details on the screen.
In deep water, increase the sensitivity and in shallow water, decrease the sensitivity.
In most situations, just setting sensitivity to “Auto” will work well.

To set the Sensitivity:

Press Menu to enter into menu setting.
Repeatedly press Menu to switch to Sonar menu.
Use the Up/Down arrow to select Sensitive option.
Press Ent to enter into setting.
Use the Up/Down Arrow to change the value.
Press Ent to confirm and exit the setting.

Note: The menu display will change from figure A to B as soon as entering menu setting.

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 FC500 fish finder display will be effected by undesired signal which may
be caused by your boat engine, turbulence, wiring, or other electrical and mechanical sources. Such
an undesired signal will produce an 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, inncreasing the noise filter will have
an effect. The larger the value is, the more unexpected sonar returns will not be displayed. If the
Noise Filter is increased too high, most sonar returns (which may be fish) will not be displayed.

In a situation where the water is clear, try decreasing the Noise Filter, however in situations where
the water is 'cloudy', then increasing the Noise Filter should be helpful.

When the water is deep enough, the high value setting may greatly affect or even hinder your
FC500 Fish finder's performance to find the bottom. So, in deep water, decreasing the Noise Filter
value will be helpful.

Note:

In some situations you may 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.

To set the Noise Filter:

Press Menu to enter into menu setting.
Repeatedly press Menu to switch to Sonar menu
Use the Up/Down Arrow to select Noise Filter option.
Press Ent to enter into setting.
Use the Up/Down arrow to change the value
Press Ent to confirm and exit the setting.

Grayline (Magic Grayline for FC500)

Grayline is used to let you see both strong and weak signals on the display.

If Grayline is “inversed”, weak returns will be shown with dark pixels and strong returns with
lighter pxels. This is very helpful or ensuring that weak signals will be clearly visible on the
display.

Note:

The magic grayline on the FC500 fish finder is featured by claculation of the sonar program.

To set the Grayline:

Press Menu to enter into menu setting.
Repeatedly press Menu to switch to Sonar menu.
Use the Up/Down Arrow to select Grayline option.

Press Ent to enter into setting
Use the Up/Down Arrow to select the option
Press Ent to confirm the setting
Press Exit to exit the setting.

Fish ID Sens.

Fish ID Sens is used to adjust the threshold of fish size detection.

If you select a higher setting, then some weaker returns can be detected and displayed as small fish
on screen, which will be very helpful when you are intending to identify small fish species.

If you select a lower setting, then only strong returns can be detected and displayed as big fish on
screen, which will be very helpful when you are intending to catch larger fish species.

To set the Fish ID Sens.

Press Menu to enter into menu setting.
Repeatedly press Menu to switch to Sonar menu.
use the Up/Down arrow to select Fish ID. Sens. option
Press Ent to enter into setting.

Press Ent to confirm the setting.
Press Exit to exit the setting.

Display

Depth Range

Depth Range determines in whichbh portion the botttom will display in the screen. (For example, if
the actual depth is 10m and the current Depth Range is 20m, then the bottom will display on 50%
portion of the screen).

There are a total of 10 levels for the depth range setting:

a) With feet unit: 10, 15, 25, 35, 50, 70, 85, 100, 131, Auto
b) With meter unit: 3, 5, 8, 10, 15, 20, 25, 30, 40, Auto

The default setting is Auto, which will keep the bottom always displayed in a proper portion on the
screen. However in some certain situations you could also manually select a depth range:

from A to B, then just press Down Arrow key to change the levels.

Zoom Range

Zoom Range is used to enlarge some certain depth segment, which is helpful for you to see small
details, fish signals and bottom structure.

Your FC500 fish finder allows you to see any depth segment with any scale.

For example, if the current depth range is 0 – 40m, by setting Zoom Range to 20-25m, you can see
the sonar image of the 20-25m depth segment with an 8x scale. And by setting it to 20-30m, you
can see the sonar image of the 30-30m depth segment with a 4x
scale.

Trouble Shooting:

You should not attempt to fix the handheld unit or the sensor. The product contains no
customizable parts. On the other hand, the waterproof performance is enabled by unique
techniques, functions of which may be disabled by unauthorized disassembly. On this account, only
professional maintenance personnel properly authorized by the Company are entitled to any repair
necessary.

In the event of problems during product use, we suggest you read the following troubleshooting
points carefully before you return the product for maintenance.

No Signal on Screen:

If the Fish finder fails to receive signals from the sensor, it will stop updating the screen (which will
then remain unchanged).

If the sonar unit cannot receive signals transmitted by the RTS sensor the screen will appear the
same until signals are restored.

The FC500 is a product which depends upon the line of sight. Obstacles between the handheld unit
and the senor can contribute to signal loss.

The FC500 has a detection depth ranging from 0.6 to 30 metres. Incorrect readings may appear in
water areas with depths less then 0.6mm. Additionally, considering the sonar physical characters,
we suggest you avoid using the product in shallow or small sized enclosed water areas.

Note: The depth is calculated from the bottom of sensor, which is fixed on your bait boat.

The maximum remote control distance for the sensor reaches 1000 feet (300m). If the sensor with
the bait boat moves out of the range, inconsistent signals may occur, or may lead to loss of signal to
the sonar unit.

Nothing is displayed after the fish finder is powered.

Be sure that the battery's positive and negative poles are correctly orientated in the holder. Also,
check that the battery has enough capacity.

When using the device in shallow water areas, the screen does not display things normally and
depths are not indiated with consistency.

The FC500 fish finder has a depth capability from 0.3 to 30m, however due to the sonar character,
the RTS sensor can only achieve the best performance in water ranging from 1.2 – 30m deep.

So, to get the best performance, we suggest you should use the fish finder in deep water rather than
shallow.

The Picture displayed on the screen vibrates.

The picture vibrates because the water 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 to be
eliminated.

The display becomes so cluttered that you cannot achieve a clear bottom:

Such cluttered display may be caused because:

The water is too shallow
The water is too cloudy
There is a lot of debris in the water.

The Sonar unit cannot reach 300m. There is an abnormal display showing on the screen and
when the bait boat is about 60 – 70m away the sonar unit stops working.

Please ensure the sensor is mounted in the proper location in your bait boat. An improper mounting
location will cause abnormal display.

Please check the RTS 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 conditions which will cause the Remote
control distance to decrease greatly.

Maintenance

With a view to getting maximum use out of your fish finder we recommend you follow the steps
below and carry out maintenance.

For the Case

Clean the sonar unit's outer case (except for the screen) with a cloth dipped in mild detergent
soluation and then wipe it dry.

For the Screen

Use a piece of soft cloth or felt to clean the screen (fresh water or eyeglass cleaner can be used if
needed). Stubborn dirt or oil stains remaining on the screen must not be wiped with force,
otherwise the surface may become scratched or damaged.

Also give daily attention to ensure the screen is kept away from any chemicals.
