Comment:

1) This radio allows for a choice of a modular power supply:  115/230 VAC, 26/36 VDC, or 13.6 VDC.
2) Alternately , the operator can configure 10 semi-duplex channels.

Semi-duplex communication connection

A radio remote control with a semi-duplex connection can send and receive signals to or from the radiographic receiver. However, at the moment that the signals are sent the remote control cannot receive any return signals from the receiver. As soon as the signal is sent, the “ears” of the remote control are open and listening for incoming signals from the specific receiver. With semi-duplex these signals are a “yes” or “no” which can be translated in a led light that goes on or off.
