    E-Compact Medium Power 5. Protections 5.1. Reflected Power If the incidence of reflected power at the transmitter due to any external or internal factor occurs, refer to the measurement screen (MEASUREMENTS [2000]) by browsing the software’s navigation Menu, according to instructions given in the Operation Section of the Digital Control System. If the value of the reflected power exceeds the value of 2%* of rated power, the control will immediately signal Through the Current Alarm LED, and this will trigger the routine protection against reflected power.

    E-Compact Medium Power 5.4. Transmitter Operating Temperature Configuration The transmitter’s operating temperature is measured on the power modules’ transistors, and is configurable between 50°C e 60°C. Configuration is done through the front panel Menu: Setup Menu “PA Temperature Control” (Setup Menu [1M00]). This configuration varies according to room temperature and the transmitter’s efficiency, and it is necessary to optimize operating temperature and equipment’s lifespan.
