TCU/TXU Front Panel Control Settings 
The front panel control switch is used to select a limited number of front panel control functions. Rotating 
the switch counterclockwise allows access to mode selection choices, while rotating the switch clockwise 
allows access to monitoring the current mode of operation. The plunger action of the switch is used to 
select the appropriate mode of operation. The TXU and associated HPU (High Power Unit), if equipped, 
is keyed ON or OFF by compressing and holding the front panel control switch for one second from any 
menu page. The Strata TX system is transmitting when the front panel blue “XMIT” LED is illuminated.  
When the menu display is inactive for more than 7 seconds, the display will revert back to the main menu.
