    • An obstacle in the fore direction not only causes a shadow zone but also aer- ated water, resulting in poor sonar performance. Be sure to locate the trans- ducer well away from any obstacle in the fore direction.
  • Page 12 Mounting method A typical mounting method is shown in the outline drawing at the back of this manual. Consult ship’s owner, dockyard and user to determine appropriate mount- ing method. Pay attention to safety (strength, watertighness) first, followed by ease of maintenance and inspection.

    Transceiver Unit Mounting considerations • The mounting location should be well ventilated and dry. • The unit can be mounted on a bulkhead or the deck. The unit weighs 8.5 kg so reinforce the mounting location if necessary. • Secure the maintenance space shown in drawing below for ease of mainte- nance and service.

  • Page 24: Display Unit

    Display Unit Mounting considerations Select the mounting location considering the following conditions: • Select a location where the display unit can easily be operated while observing the fishing ground or area surrounding the vessel. • Locate the unit at least 1 meter away from equipment which contains mag- nets (radar magnetron, loudspeaker).

  • Page 25: Motion Sensor Ms-100 (Option)

    Motion Sensor MS-100 (Option) The MS-100 measures ship’s pitching and rolling angles with sensors using the principles of the gyroscope. The MS-100 is free from error caused by ship’s ver- tical and horizontal motion. Therefore, it can be installed at any convenient loca- tion.

  • Page 29: Clinometer Bs-704 (Option)

    1.8 Clinometer BS-704 (Option) The clinometer detects ship’s inclination caused by ship’s rolling and pitching and its output is used to stabilize the sonar beam against rolling and pitching. The clinometer is, in principle, a pendulum. It measures the inclination of the ship by sensing the direction of gravity acted on it and therefore when installed on a ship, it should be placed on or near the rotation axes of the ship’s rolling and...
  • Page 30 Cautions: (1) The vicinity of the hull unit (on the ship’s bottom) is too low and should be avoided, since the polarity of the measured value is reversed. (2) When it is impossible to install the clinometer on the intersecting point of both rolling and pitching rotational axes, a special effort should be made to install it at place where the vertical distance to the intersecting point is minimum.

    g i l Adjustment of Transceiver Unit Selecting audio frequency Select audio frequency of 1000 Hz or 900 Hz by jumper connector JP2 on pcb 06P0192 in the transceiver unit. The default setting is 1000 Hz. Refer to Figure 3-1 for the location of JP2. Signal offset adjustment When noise appears on the screen, adjust R61 (offset) on pcb 06P0192.

  • Page 39: Heading Alignment

    Horizontal beamwidth When the user wishes echoes to be displayed in high resolution, turn R40 on pcb 06P0192 clockwise to sharpen horizontal beamwidth. Do not turn it excessively clockwise, or an echo which should be displayed as a single solid mass may become hollow or split into smaller, fewer masses.

    2. When the heading alignment is incorrect, loosen four bolts on the shaft retainer and then rotate the main shaft to align head- ing. 3. Tighten bolts. Adjustment of Motion Sensor, Clinometer When the ship has a semi-permanent inclination, offset it as follows. Inclination of up to 10 can be corrected.
