19.2.2.2 Tune adjustment
Note
•After replacement of the magnetron, perform rough tuning while the image is stable after setting
the radar to the Standby state for 20 to 30 minutes as the preheating time, operating the radar
from the short pulse range, and shifting the operation to the long pulse range sequentially.
•This operation is disabled when the Radar Interswitch is set to the Slave mode.
•Not displayed when the solid-state radar antenna is connected.
1 Click on the [Tune Adjustment] (rough tuning) input box.
A numeric value input keyboard is displayed. (0 to 127)
2 Enter an adjustment value (0 to 127) in the input box so that the tuning bar indicates
the maximum level (the tuning bar touches the right-most position).
For the method of using the numeric input keyboard, refer to "3.15.2 Name and function of each
section of the keyboard".
19.2.2.3 Adjusting the bearing
Adjust the bearing so that the bearing of the target measured by the compass on the ship and the
bearing of the image that is displayed on the radar match.
Note
This function is disabled when the radar interswitch is set to the Slave mode.
1 Set the bearing mode to [H UP] and set the image processing mode to [Process Off].
For the bearing mode setting method, refer to "5.4.5 Setting the azimuth mode" and for the
image processing mode setting method, refer to "5.4.4 Using video processing (Echo
Process)".
2 Measure a bearing in the ship's heading direction of a suitable target (for instance,
halted ship, breakwater, and buoy) by using the compass on the ship.
3 Click on the [Bearing Adjustment] input box.
A numeric value input keyboard is displayed.
4 Input an adjustment value in the input box so that the bearing of the target that was
measured in Step 2 indicates a correct bearing. (0 to 359.9°)
For the method of using the numeric input keyboard, refer to "3.15.2 Name and function of each
section of the keyboard".

Section 19 Adjusting and Setting up Equipment (for Services) 19-6
19.2.2.4 Adjusting a distance
Adjust the distance of the target on the screen so that the correct distance is displayed.
1 On the radar screen, specify a target whose distance is available in advance.
2 Click on the [Range Adjustment] input box.
A numeric value input keyboard is displayed.
3 Enter an adjustment value in the input box so that the distance of the target specified
in Step 1 indicates the correct distance. (128 to 1024)
For the method of using the numeric input keyboard, refer to "3.15.2 Name and function of each
section of the keyboard".
19.2.2.5 Radar operation modes
Click one of the radar operation mode buttons to select either the [Master] mode or the [Slave] mode.
