Good day , our remote turned blank and when we tried opening the battery side and it keeps having this Rd con please help we want to load electricity

The results mention meters freezing in various contexts, such as:
RF power meters freezing while transmitting
Microwave ovens potentially causing freezing damage
Software programs like Fldigi freezing during transmit on PSK31
However, none of these relate to a Conlog RF Con meter freezing up. Without more details about the specific meter model and symptoms, I cannot provide a concise solution to your query. The most relevant information is that freezing can occur with various types of meters and electronic equipment during operation, but the cause and fix would depend on the particular device and issue. More targeted troubleshooting would be needed to determine why a Conlog RF Con meter is freezing and how to resolve it
