Operating Instructions (cont'd)

Transmit

NOTE:

In the United States, FCC regulations require you to

monitor the channel before you transmit.

Press the PTT.

1 2

The active channel number glows red and the LED on

the microphone glows red while you are transmitting.

Hold the microphone 2-3 inches (5-8 cm) away

from your mouth while speaking clearly into it.

Time-Out Timer (T.O.T.) limits the amount of time you have to transmit.

When you reach the time limit, a continuous, low-pitched tone

sounds (until you release the PTT) and your transmission is cut off.

Busy Channel Lockout– Several groups of radio users may share a

channel. Busy channel lockout monitors channel activity for you (even

activity you cannot hear), preventing you from transmitting while other

groups are using a channel.

If the channel is busy when you try to transmit, a series of low-pitched

tones sounds until you release the PTT.
