Basic Transmit Operation; D Transmitting; D Microphone Gain Adjustment - Icom IC-i7410 Instruction Manual

■ Basic transmit operation

Before transmitting, monitor the operating fre-
quency to make sure transmitting won't cause
interference to other stations on the same fre-
quency. It's good amateur practice to listen
first, and then, even if nothing is heard, ask "Is
the frequency in use?" once or twice, before
you begin operating on that frequency.
