Chapter 2 OPERATIONS 2.3 POWER ON/OFF 2.3 POWER ON/OFF 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. Note: z Wait for about 2 seconds before turning on the power again.
Chapter 2 OPERATIONS 2.3 POWER ON/OFF Starting transmission 1 Press the [TX/PRF] key. The radar starts transmission and the antenna starts rotating. Reference: The radar cannot start transmission if you press the [TX/PRF] key while the preheating time is displayed. Stopping transmission 1 Press the [STBY] key on the display unit. The radar stops transmission and the antenna stops rotating. Maintain the standby state if radar observation is restarted in a relatively short time.
Chapter 2 OPERATIONS 2.4 SENSITIVITY ADJUSTMENT 2.4 SENSITIVITY ADJUSTMENT Sensitivity can be adjusted. Adjust the noise on the display unit to achieve better observation state. CAUTION If sensitivity is set too high, unnecessary signals such as noises in the receiver and false echoes increase to lower target visibility. At the same time, if sensitivity is set too low, detection of targets such as ships and dangerous objects may be hindered. Therefore, sensitivity must always be set to an optimal level.
Chapter 2 OPERATIONS 2.4 SENSITIVITY ADJUSTMENT z [GAIN] Control Turning the [GAIN] control clockwise increases receiving sensitivity and extends the radar observation range. If the sensitivity is too high, the receiver noise increases reducing the contrast between the targets and the background video. As a result, the targets become obscure on the radar display.
Chapter 2 OPERATIONS 2.5 SEA CLUTTER SUPPRESSION 2.5 SEA CLUTTER SUPPRESSION The sea clutter suppression function suppresses sea clutter returns. 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.
Chapter 2 OPERATIONS 2.5 SEA CLUTTER SUPPRESSION z [SEA] Control The sea clutter suppression function suppresses sea clutter returns by decreasing the receiving sensitivity on a short range. Turn the [SEA] control clockwise to heighten 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.
Chapter 2 OPERATIONS 2.5 SEA CLUTTER SUPPRESSION Canceling Automatic Sea Clutter Suppression Function 1 Hold down the [SEA] control. Automatic function is canceled. The mode is indicated as shown below. Reference: When the automatic mode is selected for the sea clutter suppression function, the rain/snow clutter suppression function is switched to the manual mode.
Chapter 2 OPERATIONS 2.6 RAIN/SNOW CLUTTER SUPPRESSION 2.6 RAIN/SNOW CLUTTER SUPPRESSION This function suppresses rain/snow clutter returns. CAUTION When using the sea clutter suppression function, never set the suppression level too high canceling out all image noises from the rain or snow at 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.
Chapter 2 OPERATIONS 2.6 RAIN/SNOW CLUTTER SUPPRESSION z [RAIN] Control When the [RAIN] control is turned clockwise, targets hidden by rain/snow clutter returns appear on the radar 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 using with the [SEA] control. In general, set the value to "0".
Chapter 2 OPERATIONS 2.6 RAIN/SNOW CLUTTER SUPPRESSION Switching to Manual/Automatic Mode 1 Hold down the [RAIN] control. Automatic function is canceled. The mode is indicated as shown below. Reference: When the automatic mode is selected for the rain/snow clutter suppression function, the sea clutter suppression function is switched to the manual mode.
