Talking on Your Radio
To talk to others using the radio PTT button:
1) Press and hold the PTT button and speak in a clear, normal voice about
2-3 inches away from the microphone. While you are transmitting, the
transmit icon will be shown on the display. To avoid cutting off
the first part of your transmission, pause slightly after pressing the PTT
button before you start talking.
2) When you are finished speaking, release the PTT button. You can now
receive incoming calls. While receiving, the receive icon will be
shown on the display.
Transmitting a Call Alert Tone:
Your GMRS520 radio is equipped with a call tone that will be transmitted
when the Call button is pressed.
To transmit the call alert tone, press the Call button. The tone will
automatically be transmitted for a fixed length of time.
Channel Scan Feature
Your GMRS520 radio has a channel scan feature that allows you to easily
scan all 22 channels. When an active channel is detected, the unit will
pause on that channel until the channel is clear. Then after a 4 second
delay, the unit will continue scanning. Pressing PTT while the scan is
paused on a channel will allow you to transmit on that channel.
To turn on channel scanning:
Press and hold either the Up or Down button until the radio has moved
through 14 channels. The channel number on the display will be rapidly
cycling through the channels.
To turn off channel scanning:
Press and release either the Up or Down button.
