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. 

This configuration shall be made when the equipment is activated following the procedure 

below: 

 

1.  With the transmitter running at operational power for at least 30 minutes, access the web or the PA 

USB interface to verify fan rotation. 

2.  Check fan rotation for all fans in the PAs. 
3.  Temperature adjustment must be done in order to obtain fan rotations between 5500 rpm and 6000 

rpm. 

4.  If the highest rotation is below 5500 rpm, the temperature control has to be lowered. If it is above 6000 

rpm, temperature control shall be raised. 

5.  Configure  temperature  at  Setup  Menu  “PA  Temperature  Control”.  Lower  or  raise  the  temperature 

according to description in step 4 above. It is recommended that the procedure starts in steps of 2 °C. 

6.  Once configured, wait 5 (five) minutes until transistor temperature stabilizes. 
7.  Repeat steps 3 through 6 until fan rotation is within range (5500 rpm to 6000 rpm).
