(PTT ID can be made only in analog operation.)COMPANDERIf programmed by your dealer for a channel, the compander will remove excessive noise from transmitted signals, providing higher clarity of signals. (The compander is used only in analog operation.)• Your dealer must set the compander for both the transmit side and the receive side in order for the compander to operate.TRANSMIT POWERYour dealer has programmed a transmit power level for each channel. Power levels can be high, medium (available only for NX-720H/ NX-720HG/ NX-820H/ NX-820HG), or low.](https://usermanual.wiki/JVCKENWOOD/458300/User-Guide-1993808-Page-24.png)
