Caution: When the other transducer than broadband type (TDM-052,

TDM-062) is connected, the transducer cannot perform the designated specification if frequency setting exceeds the fixed range of the transducer.

CVS-FX1 Chapter 2 Basic operation

Setting up of frequency:

1. Relation between a transceiver and display screen

For CVS-FX1, there are two types of transceiver for high frequency and low frequency, and each transceiver has two channels of channel 1 and channel 2.

High frequency 1 is the channel 1 for high frequency.

High frequency 2 is the channel 2 for high frequency.

Low frequency 1 is the channel 1 for low frequency.

Low frequency 2 is the channel 2 for low frequency.

2. Limitation in setting of high and low frequencies:

In the case of a broadband transducer, the cable at high frequency side of the transducer shall be connected to the high frequency terminal and the cable at low frequency side of transducer shall be connected to low frequency terminal.

The frequency range to be set has the following limitations per transducer.

Name of transducer

TDM-052

TDM-062

Frequency range of low frequency

38 to 75 kHz

Frequency range of high frequency

130 to 210 kHz

85 to 135 kHz

Caution: If the frequency setting exceeds the ranges above, gain will not be enough to let the transducer perform to the designated specification.

When the other transducer than broadband type is connected, please connect the cable for low frequency of the transducer to the low frequency terminal and the cable for high frequency of the transducer to the high frequency terminal, and set the designated frequency of the transducer.

3. Simultaneous transmission and reception* 1 and alternate transmission and reception* 2

Two transceivers for high frequency and low frequency transmit and receive simultaneously, and the channel 1 and channel 2 of each transceiver operate in alternate transmission and reception.

4. When the same frequency is set for high frequencies 1 and 2 or low frequencies 1 and 2, alternate transmission and reception do not operate. Transmission and reception are performed by only channel 1 and the image is displayed using the channel 1 data by the channel 2 gain setting.

5. The conditions when alternate transmission and reception can operate even when the same frequency is set for channels 1 and 2:

 If pulse width is different

 If frequency bandwidth is different

 If range is different.

 If shift is different.

 If the types of display zoom is different.

*1 Simultaneous transmission and reception: Each transmitter and receiver for high frequency and low frequency operates simultaneously.

*2 Alternate transmission and reception: Channels 1 and 2 of high frequency and channels 1 and 2 of low frequency transmit and receive alternately by each channel. The image scroll speed will drop to a half of that of simultaneous transmission and reception

2.1.4 Display of mixed images

Mixed images are combination of high and low frequency images by signal processing. The main purpose is to identify small fish, such as whitebait, from other fish school. There are 5 types for mixing methods and they are switchable in application.

Types of mixed images:

1. Mix type A

Images in high frequency and low frequency are compared. The red level signal indicates high frequency images. For the signal at lower level than that, the high frequency signal is displayed in gray color.

As fish schools with strong high frequency signal are highlighted, this is helpful for identification of fish schools near own boat’s position.

2. Mix type B

Only when high frequency signal is stronger than low frequency signal, the low frequency signal is subtracted from the high frequency signal, and the difference is displayed with color gradation.

The images existing only in high frequency are highlighted.

Small fish such as whitebait can be displayed in high frequency, but not in low frequency.

This is helpful, therefore, for identification of schools of small fish.

3. Mix type C

Images in high frequency and low frequency are compared. The red level signal indicates high frequency images. For the signal at lower level than that, only when the high frequency signal is stronger than the low frequency signal, the low frequency is subtracted from the high frequency and the difference is displayed with color gradation.

Strong signal with high frequency and images only in high frequency are highlighted.

This is helpful, therefore, for identification of fish school near own boat and school of small fish such as whitebait.

4. Mix type D

Signals of images of high and low frequencies are compared, and the stronger signal is displayed with color gradation.

This is completely combined image of high and low frequencies. Without viewing of each of high and low frequencies images, only this one image can tell the conditions in water.

5. Fish size in fish school size

Comparing signals of high and low frequencies, only signal with higher level of high frequency is displayed as difference in the order of strength, from red (strongest) to greenish yellow with color gradation. Low frequency images are indicated in greenish yellow to light blue with color gradation and the mixed image of them is displayed.

For example, when high frequency is 200 kHz, the wavelength of underwater acoustic wave is 0.75 cm, and when low frequency is 50 kHz, the wavelength of underwater acoustic wave is 3.0 cm. In the image of low frequency 50 kHz, fish smaller than 3 cm is hardly detected.

As school of small fish such as whitebait is clearly displayed in high frequency signal with short wavelength, only school of small size fish is displayed in warm color from red to greenish yellow in fish school mode.

By this, it is easy to identify smaller size than 3.0 cm.

2.1.5 Selection of pulse length

Pulse length can be switched to 4 steps: of Short, Medium, Long and Fixed.

This change of pulse length causes changes in resolution of images from the echo sounder and the signal to be displayed changes. Shorter pulse length increases resolution, but its power decreases. Other way around, longer width decreases resolution but increases power.

By this nature, the pulse length is switched depending on the range : to Short (narrow) at shallow range and to Long (wide) at deep range, except for the case of setting at [Fixed].

When pulse length is switched:

1. For the setup up of pulse length, based on the setup at [Medium] as reference, at [short], the pulse length is switched to the same pulse length as [Medium] pulse length with 1/2 of the range used, and at [Long], to the same pulse length as [Medium] pulse length with 1.5 times of the range used.

When signals in images of fish are not visible at the range used, setup at [Short] increases small response, and setup at [Long] highlights larger response while decreasing small responses.

2. When pulse length is set at [Fixed], the width is constant regardless of switching of range.

Please set at [Fixed], to avoid change of response from fish by switching of range.

To select pulse length:

1. Press [CM] key (lights red) used.

When CM1 is lit red, press [CM1] key .

2.1.6 Selection of frequency bandwidth

Frequency bandwidth can be switched to 4 steps: Narrow, Medium, Wide and Fixed. The change of frequency bandwidth results in change of the resolution of echo sounder and change of signals in the displayed images. If the frequency bandwidth is wide, the resolution becomes high. Other way around, if it is narrow, resolution becomes low.

By this nature, the frequency bandwidth is switched depending on the range: to wide at shallow range and to narrow at deep range, except for the case of setting at [Fixed].

When frequency bandwidth is switched:

1. For the setup up of frequency bandwidth, based on the setup at [Wide] as reference, at

[Medium], the bandwidth is switched over to the same bandwidth of [Wide] bandwidth that is 1.5 times of the range used, and at [Narrow], to the minimum bandwidth.

When size of target fish matches the frequency wavelength in use, setup up at [Medium] or

[Narrow] highlights the images and increase visibility. When pulse length is set at [Short] and frequency bandwidth at [Narrow], response smaller than wavelength is reduced and noise reduction effect is expected.

2. When frequency bandwidth is setup at [Fixed], the bandwidth is constant regardless of switching of range.

To select frequency bandwidth:

1. Press [CM] key (lights red) used.

When CM1 is lit red, press [CM1] key .

When Range Mode is set at manual, shift can be changed manually.

In the manual shift, there are two ways: one is to change shift positions of 4-frequency images with [All Screens Same] and another is to change images per frequency with [Scr. Individual].

The manual shift can be switched over among 4 types of shift types, [Numeric Value], [Range

Dependant], [Preset Value] and [Range Ratio].

In [Numeric Value], the shift value is changed directly.

In [Range Dependant], the shift value is changed to the most appropriate shift value specified per range.

In [Preset Value], each time shift key is pressed, 8 registered shift values switch in sequence.

In [Range Ratio], the shift value changes at every 1/5 of a range.

In addition, if [Shift digit input] is set at [F1] key or [F2] key , shift operation with a specified digit of shift value can be performed regardless of the operation mode above.

To set Range Mode at [Manual]:

1. Keep [SHIFT/M OFF] key pressed until [Range Mode] menu is displayed.

2. Move the cursor with [ ▲ ] or [ ▼ ] keys of to select [Manual].

3. Press [ENT] key . The mode is set at [Manual] and turns in manual shift.

Details of shift type:

1. Numeric Value

Each time shift key is pressed, the numeric value of shift changes.

When [ ▲ ] of [Shift] key is pressed, it shifts to the shallower direction.

When [ ▼ ] of [Shift] key is pressed, it shifts to the deeper direction.

With one press of the shift key, the digit of 1 of shift changes.

When shift key [ ▼ ] is kept pressed, the digit of 1 increases in sequence and after 9 it shifts up to the digit of 10. If it is kept pressed further, the digit of 10 increases up to 90 in sequence and then shifts up to the digit of 100. If the key is kept pressed, the digit of 100 increases in sequence. After that, even in case of beyond the digit of 1000, the digit of 100 increases.

When shift key [ ▲ ] is kept pressed, the digit of 1 decreases in sequence and after 0 it shifts up to the digit of 10. If it is kept pressed further, the value decreases down to 00 and shifts up to the digit of 100. If the key is kept pressed, the digit decreases. After this, only the digit of 100 decreases even in case of beyond the digit of 1000. When a digit shifts, the value decreases in sequence in one lower digit.

Keep pressing the key up to a just before the intended shift value, release once from the key and press it again. Repeat this operation until it can shift to the intended depth.

2.2.5 Adjustment of image gain

On CVS-FX1,gain of 4-frequency images can be adjusted individually.

For gain adjustment, there are two modes: individual mode and synchronized mode. In the individual mode, the gain is adjusted individually on a selected operation screen. In synchronized mode, the gain on all screens are adjusted all together by one gain adjustment knob after gain adjustment is optimized individually for each screens.

In the synchronized gain, the gain of all screens change keeping the gain difference between screens.

On CVS-FX1, the gain of all screens including images in the past changes by operation of the gain knobs. Also, it can be switched to a mode in which only the gain of the current image changes, to watch changes by the gain operation.

If the gain is increased too much, there is too much noise to make distinctions with signs of fish.

If the gain is decreased too much, images and fish signs become too faint to distinguish.

Adjust the gain to your preference while watching the image.

2.2.6 Adjustment of TVG

The reflected signals of echo sounder have less sensitivity due to attenuation, as depth is deeper.

This means that the same fish schools at shallower positions are displayed stronger and those at deeper positions are displayed weaker.

TVG is the function, according to the characteristics of ultrasonic sound, to correct the reflected signals attenuated according to their depth and to equalize the gain of the images along the change of depth.

In the range of depth where TVG function is effective, fish schools of the same size can be displayed with the same sensitivity even when their depth is different.

Method of TVG can be switched over between [Optimized] and [Manual].

[Optimized] is the mode with gain correction depending on the depth, based on the correction curve optimized by diffusional attenuation and absorption attenuation depending on frequency of ultrasonic.

[Manual] is the mode to adjust the setting of [Strength], [Depth] and [Adjust] to fit the images to preference.

To switch between [Optimized ] and [Manual ]:

1. Press [MENU] key .

2. The menu is displayed. Move the cursor to [TVG] with [ ▲ ] or [ ▼ ] keys of .

3. Press [ ] key of .

7. Press [MENU] key , and the menu disappears and the selected TVG is set.

CVS-FX1 Chapter 2 Basic operation

To use of optimized TVG:

 Optimized TVG corrects the reflected signal from shallower than the [Depth] where color is produced with maximum level. This is done by having room for gain adjustment, in reference to the diffusional attenuation and absorption attenuation of ultrasonic sound.

 By optimized TVG, unnecessary reflection such as noise is eliminated, and necessary reflection from single fish and fish schools is clearly displayed at the same sensitivity regardless of their depth.

 As optimized TVG always corrects optimized TVG, no adjustment is basically needed. Only fitting to a desired gain with a gain knob is required.

However, when it is felt that the gain is short due to the excess correction of TVG for shallower range, please adjust to a desired gain by changing the [Adjust].

Without TVG Optimized TVG

When adjustment is needed due to excess TVG correction for shallower range:

There are two ways of TVG adjustment: to adjust in the main menu and to assign [F1]/[F2] keys to adjust by the function keys.

CVS-FX1 Chapter 2 Basic operation

To manually correct TVG:

The reflected signals of echo sounder have less sensitivity due to attenuation, as depth is deeper.

In the TVG correction for CVS-FX1, a reference point of depth for correction is to be determined. This reference point is [TVG Depth].

Reflected signals from a shallower depth than this reference point are corrected to have the same sensitivity as that of the reference point.

In [Strength], the amount of change in this correction is set. The larger the value of [Strength] becomes, the larger the amount of change becomes. (See the figure below)

For reflected signals from shallower positions, amount of correction becomes larger. When

[Strength] is set large, the correction amount for shallow depth may seem too much. In such cases, if the [Adjust] is set at the depth at which correction seems too much, the correction amount at shallower depth than the depth becomes the same as the correction amount at the starting position, and can set off the over correction.

Setting should be performed in combination of the items above.

Adjustment of TVG strength of manual TVG:

[TVG Strength] decides the amount of change for TVG correction. The larger the value of

[TVG Strength] is, the bigger the amount of change is.

2.3 Changing of the image scroll speed

The image scroll speed can be changed at 10 steps of [Speed 1], [Stop], [Speed 2], • • •

[Speed 9]. The larger the speed number is, the slower the image scroll speed becomes.

The image scroll speed of echo sounders is faster for shallow ranges and slower for deeper ranges depending on the display ranges.

When the image speed at shallow ranges seems too fast, [Image Speed] is used to make the speed slower.

When sea bottom is bedrock and has strong reflection strength, the multipath reflection between seawater surfaces remains as reverb and may display false image* 1 .

To eliminate the false images , the image scroll speed may be slowed down to wait the next transmission and reception until the reverb disappears.

The scroll of images can be stopped.

It is possible to enlarge images by 2 times and double speed of scroll.

To change image scroll speed:

1. Press [Image Speed] key .

[Image Speed] adjustment box is displayed.

To speed up image scroll speed:

1. While [Image Speed] adjustment box is displayed, press [Image Speed] key .

Move upward the cursor, and [Image Speed] is set to a faster speed.

* 1

False image: When sea bottom material is bedrock with high reflection ratio of ultrasonic sound, the reflected signals at the sea bottom are reflected by the seawater surface and again by the sea bottom. This may be repeated many times. This repeat of reflection remains as reverb. If the reverb remains at the next transmission and reception, the image is a mixture with normal reflection and the reverb. This reverb is called as false images.

2.4 Finding out depth of targets in images (VRM operation)

VRM (Variable Range Marker) is a mobile marker to measure the depth of targets such as fish schools, and indicates lines and depth values of the lines.

This can be also used as an indication of depth for casting net, etc.

VRM can display the second VRM set at a certain interval under the first VRM. This second

VRM follows the movement of the first one with the interval. This can be used as a measure for depth of casting net.

There are two modes: to display on only one screen of the 4 frequencies and to display across the all 4 screens.

In the display on the whole screen mode, the same depth is indicated on all screens at synchronized range/shift. Display and operation can be done on each screen at individual range/shift.

2.5 Reduction of noise on images

Images of echo sounders display noise due to various causes.

The causes of noise are:

1. Interference caused by reception of signals transmitted by other echo sounders

2. Blur due to micro animate beings such as plankton

3. Noise caused by electric signal synchronized with transceiver

CVS-FX1 is equipped with functions to weaken the effect by each cause.

2.5.1 To reject interference

Interference is generated by the reception of signals transmitted by other echo sounders.

CVS-FX1 can eliminate interference by the following two methods:

1. To shift your own frequency from the frequency used by other echo sounders, to avoid reception of interference wave.

2. To reject interference by setting [IR (Interference Rejection) ] function.

2.5.2 To erase the weak response from dust and plankton, etc.

To erase the weak response from dust and microbes such as plankton in seawater, there are following 4 methods:

1. Setting TVG

2. Shortening pulse length and narrowing frequency bandwidth

3. Setting [Color Erase] function

4. Setting [IR] (Interference rejection) function

When TVG is effective:

In order to erase the response from dust and plankton at shallow depth of the displayed screen, setting TVG is effective.

TVG can be set in two ways, [Optimized TVG] and [Manual TVG].

In the case of setting in [Optimized TVG], the images are clear with less interference noise down to water depth of approximately 100 m.

As for the setting of [Optimized TVG], see “To use of optimized TVG”, p 2 - 57.

By setting [Manual TVG], noise reduction setting is possible to preference.

As for the setup of [Manual TVG], see “To adjust with manual TVG”, p 2 - 60.

When shortenin g pulse length and narrowing frequency bandwidth are effective:

When the range used is less than 100 m and the response from dust and plankton on whole screen is to be erased, it would be effective to set the pulse length at [Short] and the frequency bandwidth at [Narrow].

By this setting, fine images such as dust and plankton are erased.

It can be used for highlighting of images of aimed fish and erasing of response smaller than those.

As for the setup of [Pulse Length], see “2.1.5 Selection of pulse length”, p 2 - 19.

As for the setup of [Frequency Bandwidth], see “2.1.6 Selection of frequency bandwidth”, p 2 - 22.

When [Color Erase] is effective:

When the response from dust and plankton displayed in light bluish color is to be erased, it is effective to use [Color Erase] function.

The response of dust and plankton displayed in stronger color than green could not be erased.

The color of aimed fish images and appearance of expanding response are displayed as it is and unnecessary response from dust and plankton is erased.
