TRANSCEIVER PROGRAMMING Acknowledgment Delay - Delay time from 50-1550 ms before the scrambler responds to information received from a controller. System Delay - Delay time from 50-1550 ms between when the PTT switch is pressed and the scrambler transmits data over the air. Emergency Delay - The amount of time the scram- bler waits to send the emergency signal after the emergency switch is pressed.
TRANSCEIVER PROGRAMMING Silent Signaling - If selected, causes the scrambler to send a tone ahead of data packets that forces the receiving unit to mute its audio before the data burst is heard.
