1 RADAR OPERATION雷达操作1.1 Turning on the Power开启雷达The [POWER] switch is located at the left corner of the control unit. Open the power switch cover and press the switch to turn on the radar system. To turn off the radar, press the switch again. The screen shows the bearing scale and digital timer approximately 30 seconds after power-on. The timer counts down three minutes of warm-up time. During this period the magnetron (transmitter tube) is warmed for transmission. When the timer has reached 0:00, the indication "ST-BY" appears at the screen center, meaning the radar is now ready to transmit pulses.电源键位于控制面板的左上角。
打开电源盖、按下打开电源。
再次按下关闭电源。
电源开启后30秒屏幕显示方位圈、电子计数器，计数器倒计时3分钟磁控管预热时间。
但计数器时间归零，屏幕中央显示“待机”，表示雷达已准备发射。
In the stand-by condition, markers, rings, map, charts, etc. are not shown. Further, ARP is cancelled and the AIS display is erased.在待机的情况下，标志、距标圈、海图等将不显示。
ARPA功能取消，AIS显示取消。
In warm-up and stand-by condition, ON TIME and TX TIME counts in hours and tenths of hour appear at the screen center.在预热和待机的情况下，使用时间和发射时间键显示在屏幕中间（*.*H）。
1.2 Transmitter ON启动发射机After the power is turned on and the magnetron has warmed up, ST-BY appears at the screen center, meaning the radar is ready to transmit radar pulses. You may transmit by pressing the [STBY/TX] key on the full keyboard or roll the trackball to choose the TX STBY box at the bottom left corner of the display and then push the left button (above the trackball). The label at the left-hand side of the guidance box at the bottom right corner of the screen changes from TX to STBY在电源打开、磁控管预热后，ST-BY显示在屏幕中间，表示已准备发射。
按准备键或用鼠标选择屏幕左下角的发射准备框打开雷达。
雷达显示The radar is initially set to previously used range and pulse length. Other settings such as brilliance levels, VRMs, EBLs and menu option selections are also set to previous settings.雷达的设定（量程、脉冲长度、亮度、活动距标圈、电子方位线、菜单选项等）为上次关机时的设定。
The [STBY/TX] key (orTX STBY box) toggles the radar between STBY and TRANSMIT status. The antenna stops in stand-by and rotates in transmit. The magnetron ages with time resulting in a reduction of output power. Therefore, it is highly recommended that the radar be set to stand-by when not used for an extended period of time.ST-BY/键联系雷达待机和发射两种状态。
待机状态下天线不转动、在发射状态下转动，磁控管的使用时间影响输出功率的大小，因此前来建议在雷达长时间不使用的情况下键雷达设于待机状态。
Quick start快速启动Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can turn the radar into TRANSMIT condition without three minutes of warm-up. If the [POWER] switch has been turned off by mistake or the like and you wish to restart the radar promptly, turn on the [POWER] switch not later than 10 seconds after power-off.如果雷达仍在使用，磁控管仍然预热，可以无需等待3分钟。
如果误关机，又马上要开机，请在10秒马上打开电源。
1.3 Control Unit控制单元Two types of control units are available: Control Unit RCU-014 (full keyboard) and Control Unit RCU-105 (palm control).本雷达提供两种控制单元，RCU-014型键盘式、RCU-105型手掌式。
