Scanning is stopped at each signal worth receiving and you can listen in to the conversation.
If you leave the set alone it will re-start a) after the communication on the channels has stopped or
b) after about 5 seconds observation time, if the communication should last longer.

between receiving and transmitting:
•
Press
PTT
button to transmit.
Your radio is equipped with a TX control LED, this will light when You are transmitting
on an allowed channel in an allowed mode.
•
Release
PTT
button again to switch back to receiving.
When the transmission
PTT
button is depressed, you can speak from a distance of about 5-10 cm
into the microphone. After pressing the
PTT
button, please wait about ½ second before You start
speaking. Please remember- that different from GSM phones- You share one channel common for
transmit and receive, and your transmitter and the receiver(s) on the distant side need a certain
time to switch on. The modulation amplifier of your AE 6690 is sensitive enough and enables you
in most cases to speak with even more distance, depending on how loud your voice is. An
automatic regulator ensures that your partner always hears your signal at the same volume.
It is best to test the best distance from the microphone for yourself with the help of another station.
