INTRODUCTION Congratulations on your choice of the ONW A KF-667 Color Video Sounder . We are confident that you will enjoy many years of operation with this fine piece of equipment. The KF-667 is just one of the many ONW A developments in the field of echo sounding.
Alarms: fish, bottom, water temperature (requires appropriate sensor). Six pulse lengths for excellent performance on both shallow and deep ranges. Universal 12-24 VDC power supply drawing 30 W of power at maximum. Water temperature sensor optionally available.
PRINCIPLE OF OPERA TION This Color V ideo Sounder determines the distance between its transducer a nd underwater objects such as fish, lake bottom or seabed and displays the results on a 5.

2.BASIC OPERA TION 2.1 T urning the Power On/Off Tu rn the [MODE] switch clockwise to turn the power on. The unit starts with the settings used before it was turned off last time. T o turn the power off, turn the switch fully counterclockwise. 2.2 Adjusti ng Brilliance Use the [BRILL] key to adjust the brilli ance.
2.3.2 Display mode description 200K, 50K (high frequency , low frequency) mode The sounder uses ultrasonic pulses to detect bottom conditions. The lower the frequency of the pulse the wider the detection area.
ZOOM mode (high or low frequency) Three types of zoom displays are available: marker zoom, bottom-lock expansion, bottom zoom. The zoom mode to be used can be selected on the main menu with ZOOM MODE.
2.4 Adjust ing Gain The [GAIN] control adjusts the sensitivity of the receiver. A djust it so that a slight amount of noise remains on the screen. Generally , use a higher gain setting for greater depths and a lower setting for shallower waters. Note: The [GAIN] control is inoperative when the automatic mode is active.
2.6 Selecting Picture Advance Speed The picture advance speed determines how quickly the vertical scan lines run across the screen. When selecting a picture advance speed, keep in mind that a fast advance speed will expand the size of the fish school h orizontally on the screen and a slow advance speed will contract it.
Operate the [RANGE] switch and the display shown below appears. A djust the [RANGE] control again to select a basic range. RANGE: 30 Note: The [R ANGE] switch is ino perative when the a uto fu nction is act ive. 2.7.2 Range shifting The basic range may be shifted up or down with the [SHIFT] k eys ([+],[-]).
2.9 Measuring Depth to a Fish School The VRM (V ariable Range Marker) functions to measure the depth to fish schools or other echo. 1.Press[ ]or[ ]to place the VRM on an echo.
2.1 1 Menu Operation The menu, consisting of the main menu a nd system menus, contains less often used functions which d o n ot require frequent adjustment. 2.1 1.1 Menu selection 1.Set the [MODE] switch i n t he MENU1 position. *A shown when auto mode in active.
4.Press[ ]or[ ]to select menu item. 5.Press[+]or[-] to set conditio n. 6.Set the [MODE] switch in any other position to register s election and close the menu. 2.1 1.2 Main menu description Menu item description NOISE LIMITER Eliminates noise from other echo sounders and electrical interference.
2.1 1.3 System menu description Menu item Description System Menu DEPTH Selects unit of depth measurement; meters, feet, fathoms, passi/braza. SPEED Selects unit of speed measurement; knots, miles per hour, kilometers per hour. TEMP Sel ects unit of temperature measurement; Celsius and Fahrenheit.
2.12 Suppressing Interference Interference from other acoustic equipment operating nearby or other electronic equipment on your boat m ay show itself on the display as shown below . T o suppress interference, do the following: 1.Select MENU1 with the [MODE ]switch.
2.14 Selecting Background and Echo Colors 1.Select MENU1 with the [MODE] switch. 2.Select HUE SELECTION. 3.Press [+] or [-] to select h ue arrangement desired, referring to the table below. Hue options Hue Ho. Background color Echo color Blue Blue Black Black White White Black 2.
2.15.2 Activating/deactivating an alarm 1.Prees the [ALARM] k ey to display the alarm menu. 2.Press [ ] or [ ] to select an a larm . 3.Press [+]to select ON, IN o r OU T .
2.16 White Marker The white marker functions to display a particular echo color i n white. For example, you may want t o display the bottom echo (reddish-brown) in white to discriminate fish echoes near t he bottom. Note that t he bottom must be display ed in reddish-brown for the white marker to function.
3. INTERPRETING THE DISPLA Y 3.1 Zero Line The zero line (sometimes referred to as the transmission line) represents the transducer`s position, and moves off the screen when a deep phased range is used. 3.2 Fish School Echoes Fish school echoes will g enerally be plotted between the zero line and the bottom.
3.4 Surface Noise/Aeration When the waters are rough or the boat passes over a wake, surface noise may appear near the zero line. A s surface turbulence is acoustically equivalent to running into a brick wall, the bottom echo will be displayed intermittently .
4. MAINTENANCE,TROUBLESHOOTING WARNING ELECTRICAL SHOCK HAZARD Do not open the equipment. Only qualified personnel should work inside the equipment. 4.1 Maintenance Regular maintenance is important for good performance. Following the recommended maintenance procedures will help keep your s et in good working condition.
4.1.3 Cleaning Keep the equipment clean and dry at all times. Dust or loose dirt should be wiped off with a soft, dry cloth. Do not use chemical c leaners to clean the displa y unit-they can remove paint or markings. 4.1.4 Maintenance of the transduc er Marine life on the transducer face will r esult in gradual d ecrease in the sensitivity .
4.2 Basic T roubleshooting The troubleshooting table below presents common problems and the means to restore normal operation. If normal o peration cannot be restored do not attempt to check inside the equipment. Basic trou bleshooting If Then Neither echo nor fixed range scale appears check battery voltage.
4.3 T ransducer Check A simple and reliable check of the transducer i s to temporarily replace the transducer with a ne w one. I f the sensitivity is considerably improved through this change, the transducer i s probably faulty . This method is especially useful for inside-hull or through-hull installation.
