For Sub, the Video Initial Adjust is required (page 3-6). Antenna Height: Set the height of the antenna above the water surface among 5, 10, 15, 20, 30, 40 and 50 m. The default setting is 15 m. Antenna Rotation: Rotate, the default setting, stops transmission when the antenna is not rotating. Stop transmits radar pulses without rotating the antenna. Local Time Offset: To display local time on the screen, set the time difference from the UTC. Memory Clear: Restore the default settings. However, Purpose, Type, View Position and Input Source are not restored.

Heading Adjustment

You have mounted the antenna unit facing straight ahead in the direction of the bow. Therefore, a small but conspicuous target dead ahead visually should appear on the heading line (zero degrees). In practice, you will probably observe some small error on the display because of the difficulty in achieving accurate initial positioning of the antenna unit. The following adjustment will compensate for this error. 1. Set ships heading toward a suitable target (for example, ship or buoy) at a range between 0.125 and 0.25 nautical mile.
2. Transmit the radar at 0.25 nm range and measure the bearing of that target relative to ships heading with an EBL. 3. Open the Installation menu, and choose Heading Adjust. 4. Press the ENTER key to show the HEADING ADJUST window.

0 (0 359 )

5. Rotate the trackball upward or downward to set the value measured at the step 2 above. Confirm that the target shows dead ahead on the screen. 6. Press the ENTER key to conclude the setting.

Auto Installation Setup

When this item is executed, the tuning, timing, video and MSB are automatically adjusted. Note: Before executing this procedure, confirm that Sector Blank 1 and Sector Blank 2 are off. 1. Transmit the radar at 48 nm range. 2. Choose Auto Installation Setup from the installation menu and press the ENTER key. 3. Rotate the trackball to choose Yes, and then press the ENTER key. Automatically, the tune adjustment begins, indicating Tuning adjusting. Then, the timing adjustment, video adjustment and MSB adjustment are executed automatically, indicating Timing adjusting, Video adjusting, and MSB adjusting in that order. After the adjustment is completed, the window disappears. If you are not satisfied with the result of the Auto Installation Setup, execute Manual Timing Adjust, Tuning Initial Adjust, Manual MSB Adjust and Video Initial Adjust as follows.

Tuning Initial Adjust

1. 2. 3. 4. Transmit the radar at 48 nm range. Open the Installation menu, and choose Tuning Initial Adjust. Press the ENTER key to show the setting window. Rotate the trackball to choose Yes, and then press the ENTER key. The tune adjustment begins, indicating Tuning adjusting. After the adjustment is completed, the window disappears.

Manual Timing Adjust

This adjustment ensures proper radar performance, especially on short ranges. The radar measures the time required for a transmitted echo to travel to the target and return to the source. The received echo appears on the display based on this time. Thus, at the instant the transmitter is fired, the sweep should start from the center of the display (sometimes called sweep origin.) A trigger pulse generated in the display unit goes to the antenna unit through the signal cable to trigger the transmitter (magnetron). The time taken by the signal to travel up to the antenna unit varies, depending largely on the length of signal cable. During this period the display unit should wait before starting the sweep. When the display unit is not adjusted correctly, the echoes from a straight local object (for example, a harbor wall or straight pier) will not appear with straight edges namely, they will be seen as pushed out or pulled in near the picture center. The range of objects will also be incorrectly shown.

(1) Target pulled

(2) Correct
(3) Target pushed outward
Examples of improper and correct sweep timing
1. Transmit on the shortest range and confirm that gain and A/C SEA are properly adjusted. 2. Visually select a target which forms a straight line (harbor wall, straight piers). 3. Open the Installation menu and choose Manual Timing Adjust. 4. Press the ENTER key to show the setting window. 5. Rotate the trackball to straighten the target selected at step 2, and then press the ENTER key to finish.

Manual MBS Adjust

Main bang (black hole), which appears at the display center on short ranges, can be suppressed as follows. 1. 2. 3. 4. 5. Transmit the radar on the short range. Open the Installation menu and choose Manual MBS Adjust. Press the ENTER key to show the setting window. Rotate the trackball to suppress main bang (between 0 and 255). Press the ENTER key to finish.

Video Initial Adjust

After completing Auto Installation Setup, you can fine tune the video signal. 1. Transmit the radar and set as follows. Gain: one oclock A/C Sea: zero A/C Rain: zero Echo Average: Off Noise Rejecter: Off Interference Rejecter: Med. 2. Open the Installation menu and choose Video Initial Adjust. 3. Press the ENTER key to show the setting window. 4. Rotate the trackball to adjust the video so that the white noise slightly appears. The setting range is 0 to 31. The greater the value, the higher the gain. 5. Press the ENTER key to finish. Note: If the display unit is used as a Sub-display, set the Input Source to Sub and perform the Video Initial Adjust as mentioned above so that the echo presentation on the sub-display is the same as that on the main display.
