Marine radar images appear fuzzy how to deal with

After using Marine radar for a certain period of time, the image may become blurred and dim. In this case, we need to carry out the following operations:

1. Use YAR27's self-test function to check whether the high voltage (HV) is normal (about 330V), and replace the high pressure plate if it is abnormal;

2. Under the same self-check function, check whether the tune voltage is normal (32V); if not, replace the rf power board;

3. If there is a PM (performance monitor), check whether the transmitting power of the magnetron decreases under the PM function, and replace the magnetron if there is a decrease.

After a period of use, the Marine radar will have a certain degree of image blurring and dimming, which will affect the normal use in the process of running. Therefore, it is necessary to check the Marine radar regularly in accordance with the above methods, so as to minimize the occurrence of such conditions and improve the utilization rate of the Marine radar.
