Resumen del manual
Tighten the knobs securely. CAUTION If the hanger vibrates too much from side to side, use the supplied rubber cushions to absorb the vibrations. CABLE CONNECTIONS Cable connections to the FE-4300 recorder unit are made at the connectors located at the rear of the unit. Fig. 11 shows the wiring instructions. 12 Transducer Cable Connection to Recorder Unit In order to minimize the chance of picking up electrical interference, avoid where possible routing the transducer cable near other on-board electrical equipment. Also avoid running the cable in parallel with power cables. Power Cable Connection The FE-4300 is designed to operate normally at any voltage between 11 and 15Vdc. The power should be directly taken from the distribution board or breaker panel. Connect the red lead of the cable to the positive (+) terminal of the battery and the black lead to the negative (-) terminal. CAUTION REVERSING THE POLARITY WILL RESULT IN BLOWING THE FUSE AND MAY VERY WELL DAMAGE INTERNAL COMPONENTS. GROUNDING The FE-4300 is designed to operate normally without grounding the recorder unit, provided that the cable routing precautions stated before are taken. However in some cases, interference may show up at high gain settings, and it may become necessary to ground the unit to the boat's grounding bus to eliminate the problem. In such cases, run a heavy duty ground wire from the grounding terminal on the rear bottom of the recorder unit to the nearest grounding point on the boat. On a fiberglass boat, it is best to install a ground plate that measures about 20 cm by 30 cm (0.8 feet by 1.0 feet) on the outside of the hull bottom to provide a ground point. If this is not practical, the engine block can be used. 13 LOADING OF RECORDING PAPER Prior to operating the FE-4300, it is necessary to load the recording paper into the unit. Loading is made easy by means of a cassette-type paper holder. The procedure for paper loading is shown in fig.12 below. Open the front panel. Press the clamper, and the cassette for paper loading will pop-out. Take it out from the main unit. Feed the recording paper referring to the illustration at left, and wind the paper to correct a sag. Insert the loading cassette into its compartment, making sure the pin and hook are mated. You should hear a click sound indicating that the cassette is engaged correctly. When a red arrow appears on the roll this indicates 1.5 meters of paper remains. (The mark appears when 10% of the total length of the roll remains.) Fig. 12 Loading the Recording Paper 14 OPERATIONAL OVERVIEW The FE-4300 is very easy to operate. For most operations, each time a control touchpad is pressed an audible "beep" is produced to signal the operator that the unit has received his command. Furthermore, if you hold down any of the upper-four control touchpads, the appropriate on-LCD indications will automatically increment, either upwards or downwards. The lower-four touchpads are on-off switches and their status appears on both the recording paper and the LCD window. The Recorder Unit is separated into two sections; controls on the right-hand side with a small LCD window, and the recording part on the left-hand side. Most of the touchpad controls have associated with them an indication on the recording paper using the same label found on the touchpad. Changing a touchpad setting will cause a corresponding change in the indication on the LCD window for a few seconds and the recording paper, as well as a change in the appearance of the echoes being viewed. To familiarize yourself with the controls of your unit, turn it on (presuming that it has already been installed) and try pushing some of the keys as you review this section. CONTROLS Power Switch Key: Power is supplied to the unit by pressing the power switch key. Every time power is applied, the internal settings will default to the following: LCD Window O I Power Switch Key Fig. 13 Front Panel Controls Phased Range: Basic Range: "0" Shadow Line : Range Marker: Paper Illumination : "OFF" "ON" "OFF" Paper Advance Speed: "2"(M) 15 Noise Limiter: Alarm: Bottom Lock: "OFF" "OFF" "OFF" Stand-by: Gain Control: "OFF" "5" To turn off the unit, press the power switch again. Range Selection: The *| Basic Range and Phased Range keys used together give the operator the means to seloct the depth he can observe directly under the boat. The Basic Range can be thought of as providing a "window" into the water column. The start of this window is determined by the setting of the Phased Range selection. For example, if you select Basic Range 5, you will have a 240-foot deep viewing area, which may be moved anywhere in the water column by using the Phased Range key. To continue our example, if the Phased Range selector is set to 60 feet, the top of the range window would be at 60 feet, and the bottom of the range window would be at 240 plus 60 feet, or 300 feet.
