If you put anything hot on it, it may be deformed. z Do not give any impact to the operation panel, trackball, or controls. Otherwise, any failure or damage may result. Attention POWER ON AND START THE SYSTEM OBSERVE AND ADJUST VIDEO ACQUIRE AND MEASURE DATA END THE OPERATION AND STOP THE SYSTEM

3-2 3.1 Operation Flow yy y3 z Wait for about 2 seconds before turning on the power again. z Immediately after the radar is installed, at start of the system after it has not been used for a long time, or after the magnetron is replaced, preheat the equipment in the standby state for 20 to 30 minutes before setting it into the transmit state. z If the preheating time is short, the magnetron causes sparks, resulting in its unstable oscillation. Start transmission on a short-pulse range and change the range to the longer pulse ranges in turn. If the transmission is unstable in the meantime, immediately place the system back into the standby state and maintain it in the standby state for 5 to 10 minutes before restarting the operation. Repeat these steps until the operation is stabilized. 3.1.1 Power ON and Start the System CAUTION A malfunction may occur if the power in the ship is instantaneously interrupted during operation of the radar. In this case, the power should be turned on again. Attention

3-3 Procedures 1 Check that the ship’s mains are turned on. 2 Press the [STBY] key. The system is turned on, and the preheating time is displayed. Preheat is indicated upper left of the display. 3 Wait until the preheating time is over. When the preheating time is over, the preheating time screen disappears, and Preheat upper left of the display changes to Standby . 4 Press the [TX / PRF] key. The radar will start transmission and the antenna will start rotating. Standby upper left of the display changes to Transmit . Note: The radar does not start transmission if you Press the [TX / PRF] key while Preheat is indicated. 3.1.2 Observe and Adjust Video Procedures 1 Press the [RANGE+] key or [RANGE-] key to set the range to the scale required for target observation. 2 Turn the dials [GAIN / PL], [AUTO-SEA], and [AUTO-RAIN] to obtain the clearest targets. Refer to [GAIN/PL]→3-7P [AUTO-SEA]→3-8P [AUTO-RAIN]→3-10P for how to use each dial. For how to adjust video, see Chapter 3.2. 3.1.3 Acquire and Measure Data For details on how to acquire data and measure, see Section 4 "Measurement of range and bearing." 3.1.4 Display and Measure with Reference to CCRP The radar video, range, bearing, Target Tracking and AIS data display etc... are displayed with reference to CCRP (Consistent Common Reference Point). If scanner is switched, these data are measured from CCRP. If some kind of functions set scanner position to outside of the PPI range, these data except Target Tracking and AIS data are displayed with reference to scanner position. For how to setting CCRP, see the section 7.1.9.

3-4 3.1 Operation Flow yy y3 3.1.5 End the Operation and Stop the System Exit 1 Press the [STBY] key. The radar will stop transmission and the antenna will stop rotating. Transmit upper left of the display changes to Standby . Maintain the standby state if radar observation is restarted in a relatively short time. Only pressing the [TX / PRF] key starts observation. 2 Press the [STBY] key and the [TX / PRF] key together. The system will be turned off.

3-5 3.2 OBSERVE AND ADJUST VIDEO 3.2.1 Adjust Monitor Brilliance [BRILL] Procedures 1 Obtain the best-to-see display with optimum brilliance by turning the [BRILL] dial at the lower right of the LCD monitor. Turning the [BRILL] dial clockwise increases the brilliance of the entire display. Conversely, turning the [BRILL] dial counterclockwise decreases the brilliance of the entire display. In consideration of the ambient brightness, adjust display brilliance that is high enough to easily observe the radar display but does not glare. 3.2.2 Change Observation Range [RANGE + / - ] Procedures 1 When increasing the observation range, press the [RANGE+] key. Increasing the observation range will enable a wider range to be observed. However, a video image is small and the ability to detect targets near own ship decreases. Therefore, when observing the vicinity of own ship, use the smaller observation range. 2 When decreasing the observation range, press the [RANGE-] key. Decreasing the observation range will enable the vicinity of own ship to be enlarged. However, caution must be taken because video images of the area beyond the observation range cannot be displayed.

3-6 3.2 Observe and Adjust Video yy y3 3.2.3 Tune CAUTION Normally, use the automatic tune mode. Use the manual tune mode only when best tuning is not possible in the automatic tune mode due to deterioration of magnetron. This radar system provides the automatic tune mode and the manual tune mode. The automatic tune mode automatically adjusts the tuning of the transmitting frequency and the receiving frequency, and the manual tune mode enables tuning to be adjusted by using the dial located on the operation unit. The tune mode currently being used is displayed in the tune mode switching (lower left of the display ⑫ on page 2-18). When using the automatic tune mode Procedures 1 Put the cursor on the tune mode switching (lower left of the display ⑫ on page 2-18) and press the [ENT] key. The automatic tune mode is selected and AUTO is displayed in the tune mode field. Tune adjustment is automatically conducted. Tune is adjusted at the start of transmission, at the change of the range or pulse length. Tune adjustment is completed within several seconds. When using the manual tune mode Procedures 1 Put the cursor on the tune mode switching (lower left of the display ⑫ on page 2-18) and press the [ENT] key to set the manual tune mode. The automatic tune mode is cancelled, and MAN is displayed in the tune mode field. 2 Press the [MULTI] dial to set the ( Tune ) mode. Tune is displayed in the multi-dial mode (lower left of the display on page 2-3). 3 Turn the [MULTI] dial to adjust tune. Make adjustments so that the tuning indication (upper left of the display on page 2-2) indicates the maximum.

3-7 3.2.4 Adjust Gain [GAIN / PL] CAUTION If the gain is too high, unnecessary signals including receiver noise and false video increase resulting in reduction of visibility of targets. On the contrary, if the gain is too low, targets including ships and dangerous objects may not be clearly indicated. Procedures 1 Adjust noise of the display by turning the [GAIN / PL] dial until targets can be easily observed. Turning [GAIN / PL] dial clockwise increases gain. Turning [GAIN / PL] dial counterclockwise decreases gain. By increasing receiving gain, the range to observe radar video is widened. To observe densely crowded targets or short-range targets, reducing the receiving gain will enable the targets to be easily observed. It is recommended to restore the setting to the factory default, if you lost the appropriate settings. The factory default level is shown on the bar chart as a green line. The factory default level is assigned by every function mode. See the Section 3.9 “USE FUNCTION KEY [FUNC]”. Current PositionDefault Position

3-8 3.2 Observe and Adjust Video yy y3 3.2.5 Suppress Sea Clutter [AUTO-SEA] CAUTION When using the sea clutter suppression function, never set the suppression level too high canceling out all image noises from the sea surface at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited. When using the sea clutter suppression function, make sure to choose the most appropriate image noise suppression level. Using the manual sea clutter suppression mode Procedures 1 Adjust the sea clutter returns of the display by turning the [AUTO-SEA] dial until targets can be easily observed. Turning [AUTO-SEA] dial clockwise suppresses sea clutter returns. Turning [AUTO-SEA] dial counterclockwise intensifies sea clutter returns. The sea clutter suppression function suppresses sea clutter returns by decreasing the receiving gain on a short range. Turning the [AUTO-SEA] dial clockwise heightens the effect of sea clutter suppression. However, be careful that excessive suppression causes low signal-strength targets such as buoys and boats to disappear from the radar display. It is recommended to restore the setting to the factory default, if you lost the appropriate settings. The factory default level is shown on the bar chart as a green line. The factory default level is assigned by every function mode. See the Section 3.9 “USE FUNCTION KEY [FUNC]”. Current PositionDefault Position

3-9 Using the automatic sea clutter suppression mode The sea clutter suppression in accordance with the intensity of sea clutter is possible. Use this mode when the sea clutter's intensity differs according to directional orientation. Procedures 1 Press the [AUTO-SEA] dial. The automatic sea clutter suppression mode is selected, and AUTO is displayed in sea clutter suppression (Sea) mode switching (lower left of the display ⑩ on page 2-18). 2 Make adjustments by turning the [AUTO-SEA] dial. Even when the automatic sea clutter suppression mode is selected, turning the [AUTO-SEA] dial can make fine adjustments manually. Note: When the automatic sea clutter suppression mode is selected, the automatic rain/snow clutter suppression mode is switched to the manual mode. To select both the sea clutter suppression function and the rain/snow clutter suppression function in the automatic mode, use the automatic rain/snow clutter suppression mode. Cancellation 1 Press the [AUTO-SEA] dial. The automatic sea clutter suppression mode is cancelled, and MAN is displayed in the sea clutter suppression (Sea) mode field.

3-10 3.2 Observe and Adjust Video yy y3 3.2.6 Suppress Rain / Snow Clutter [AUTO-RAIN] CAUTION When using the rain / snow clutter suppression function, never set the suppression level too high canceling out all image noises from the rain or snow at the close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited. When using the rain / snow clutter suppression function, make sure to choose the most appropriate image noise suppression level. Using the manual rain / snow clutter suppression mode Procedures 1 Adjust the rain / snow clutter returns of the display by turning the [AUTO-RAIN] dial until targets can be easily observed. Turning [AUTO-RAIN] dial clockwise suppresses rain / snow clutter returns. Turning [AUTO-RAIN] dial counterclockwise intensifies rain / snow clutter returns. When the [AUTO-RAIN] dial is turned clockwise, the rain / snow clutter suppression function suppresses rain / snow clutter returns and gets targets hidden by rain / snow clutter returns to appear of the display. However, be careful that excessive suppression may cause small targets to be overlooked. Since the rain / snow clutter suppression function also has the effect of suppressing sea clutter, the suppression efficiency improves when the [AUTO-RAIN] dial is used with the [AUTO-SEA] dial. In general, turn the [AUTO-RAIN] dial fully to the left. It is recommended to restore the setting to the factory default, if you lost the appropriate settings. The factory default level is shown on the bar chart as a green line. The factory default level is assigned by every function mode. See the Section 3.9 “USE FUNCTION KEY [FUNC]”. Current PositionDefault Position

3-11 Using the automatic rain / snow clutter suppression mode The rain / snow clutter suppression in accordance with the intensity of rain / snow clutter is possible. Use this mode when the rain / snow clutter's intensity differs according to directional orientation. Procedures 1 Press the [AUTO-RAIN] dial. The automatic rain / snow clutter suppression mode is selected, and AUTO is displayed in the sea clutter suppression (Sea) mode switching and the rain / snow clutter suppression (Rain) mode switching ( lower left on the display ⑩ and ⑪ on page 2-18) 2 Make adjustments by turning the [AUTO-RAIN] dial and the [AUTO-SEA] dial. Even when the automatic rain / snow clutter suppression mode is selected, turning the [AUTO-RAIN] dial and the [AUTO-SEA] dial can make fine adjustments manually. Note: When the automatic rain / snow clutter suppression mode is selected, the automatic sea clutter suppression mode is also activated. It is not possible to set only the rain / snow clutter suppression function to the automatic mode. Cancellation 1 Press the [RAIN] dial. The automatic rain / snow clutter suppression mode is cancelled, and AUTO is changed to MAN in the sea clutter suppression (Sea) mode field and the rain / snow clutter suppression (Rain) mode field. 3.2.7 Reset Alarm Buzzer [ALARM ACK] When an audible alarm is issued, use [ALARM ACK] to acknowledge the alarm information, stop the alarm buzzing, and stop the alarm lamp flashing. (If more than one alarm has occurred, press the key for each alarm indication.) The alarm stops buzzing, but the alarm indication does not disappear. Procedures 1 Press the [ALARM ACK] key. The alarm will stop buzzing.

Procedures 1 Press the [FUNC] key for 2 seconds. The User Function Setting menu will appear. Specify the number for the function for which the settings are to be changed. The following are the operation overviews of each function setting item. [Page 1] [1] Mode • Selects the function name to be indicated at the lower left of the display when the function is selected. • When the setting is changed back to the factory setting, the initial value of the selected mode is called. • The following 11 modes are provided. Coast : Use this mode to monitor a relatively short range, for example, bays and coasts where many boats and ships are running. (Importance is attached to resolution.) Deepsea : Use this mode to monitor a relatively long range, for example, the open sea. (Importance is attached to long-range gain.) Fishnet : Use this mode to detect small targets such as fishnets of round haul netters hidden by sea clutter returns. (Importance is attached to sea clutter suppression, and gain to moving targets lowers.) Storm : Use this mode when many rain / snow clutter returns or sea clutter returns are detected in stormy weather. (Importance is attached to rain / snow clutter and sea clutter suppression, and gain slightly lowers.) Calm : Use this mode when only a few rain / snow clutter returns or sea clutter returns are detected. Rain : Use this mode when sea clutter is not strong but rain / snow clutter is strong. (Importance is attached to rain / snow clutter suppression, and gain slightly lowers.) Bird : Use this mode to detect flocks of sea birds. Long : Use this mode to monitor utmost distances in the broad ocean. Buoy : Use this mode to detect small targets like radio buoys in areas outside the sea clutter area. (This mode displays targets of which detection probability is low.) User1 : General mode used when the nine modes above are not applicable. User2 : General mode used when the nine modes above are not applicable. [Page 1] [2] IR (Interference Rejection) • Same function as IR described in Section 3.4.1.

[Page 1] [4] Target Enhance • Same function as Target Enhance described in Section 3.4.3. [Page 1] [5] Auto STC / FTC (Auto Sea / Rain) • Detects unwanted waves such as rain / snow clutter and sea clutter and automatically suppresses them. • When the sea state or weather changes, this function automatically performs suppression processing in accordance with the situation. • Suppression processing is not full automatic, and requires the operator to adjust the afterimages of unwanted waves. • To adjust the afterimage of sea clutter, use the [SEA] dial. • To adjust the afterimage of rain / snow clutter, use the [RAIN] dial. • In areas where the density of unwanted waves is low, unwanted waves may remain being judged as targets. Thus, use the automatic clutter suppression mode together with the video process mode. • Characteristics of the automatic clutter suppression function. Off : Disables the automatic clutter suppression function. Select off when rain / snow clutter and sea clutter are not strong or when the ship is in a bay. AUTO Sea : Automatically detects the strength of sea clutter, and performs the most suitable sea clutter suppression processing. Even when the strength of sea clutter varies depending on the wind direction, AUTO Sea performs the most suitable suppression processing. Land like islands can be displayed naturally. Since rain clouds outside sea clutter areas are recognized as land, there is no effect of suppressing rain / snow clutter. AUTO Sea/Rain : Along with AUTO Sea, AUTO Rain automatically detects the strength of rain / snow clutter, and performs the most suitable rain / snow clutter suppression processing. When rain clouds are scattered about, AUTO Rain performs rain / snow clutter suppression processing for only the rain-cloud areas. Since land is recognized as rain clouds, land videos become obscure. [Page 2] [1] - [7] Pulse Length • Sets the standard transmitter pulse length in each range. • When the range is called, the pulse range is used. [Page 3] [1] - [7] Process Setting • Operation is the same as that of the Process Setting menu described in Section 3.8.1.

3-99 [Page 4] [1] - [7] Trails Setting • Same functions as in the Trails Setting menu described in Section 3.8.2. [Page 5] [1] Gain Offset • Corrects gain while the function mode is called. • Since the displayed noise level varies depending on the combination of the video process mode and the interference rejection level, gain needs fine adjustment for always obtaining the highest level. • The gain correction function saves the correction value set by the gain adjust in each function mode, so it can obtain the highest gain without the gain adjust being operated when the function mode is changed. • To set high gain, set a value on the “+” side. • To set low gain, set a value on the “-” side. • When the radar interference rejection level is increased, the noise level is lowered. Thus, set a gain correction value to the “+” side. • When the video process mode 3Scan CORREL , 4Scan CORREL , or 5Scan CORREL is used, the noise level is lowered. Thus, set a gain correction value to the “+” side. • When the video process mode Remain or Peak Hold is used, noise is hard to disappear. Thus, set a gain correction value to the “-” side. [Page 5] [2] PRF • Same function as in the Pulse Repetition Frequency described in 3.8.3. [Page 5] [3] Small Buoy Detection • When the automatic sea clutter suppression function is used, this mode is used to process signals for detecting small targets. Off : Activates the general signal processing mode. On : The signal processing mode for detecting small targets.

Off : Activates the general signal processing mode. On : Activates the fishnet detection mode. [Page 5] [5] Antenna Height • Set the height of radar antenna above sea level. • The STC/FTC curve is changed. -5m : Set the antenna height under 5m. 5-10m : Set the antenna height 5m to 10m. 10-20m : Set the antenna height 10m to 20m. 20m- : Set the antenna height over 20m.
