GMRS Standby Mode

The GMRS (General Mobile Radio Service) Standby feature is a land-mobile service available for short-distance, two- way communications in the USA. You must have a valid FCC license to communicate on these channels (see page 28).

While in GMRS Standby mode, the user will be able to Transmit (Tx) by pressing the Push to Talk (Talk) button. Signals in Receive (Rx) mode will be received on the selected channel(s).

When in GMRS Standby mode, the radio has the ability to receive calls as well as transmit calls.

NOTE

As GMRS channels are scrolled, you will see CTCSS or DCS icons displayed on the LCD screen if the codes have been previously programmed. You will only hear transmissions from other radios with the equivalent subcodes programmed.

When a transmission is received, the following icons will be displayed.

Transmit (Tx) and Receive (Rx) Modes

Transmit (Tx) and Receive (Rx) modes gives you the ability to interact with other GMRS radios. When you use this capability, be sure to follow the procedures and to observe the courtesies that govern its use so everyone benefits. (See pages 18 through 27) to help you select the proper channels.

When a talk transmission occurs, the following icons will be displayed.

To Transmit a Message:

1.Check to see that your radio is set to a proper channel for the type of message you plan to send.

2.Toggle to the Low Power setting.

3.With the microphone about 2 in. [5 cm] from your mouth, press and hold the Talk button and speak into the microphone. The Tx icon will appear on the LCD.

4.Release the Talk button when you are finished speaking. Your radio can only operate in either Transmit (Tx) or Receive (Rx) mode at any given time. You will not hear the response to your message unless the Talk button is released. If the Battery Power icon begins blinking on the LCD when the Talk button is pressed, the radio will NOT transmit.

NOTE

If the Talk button is held down for five (5) minutes, the radio will automatically sound a series of beeps and cease transmitting to prevent unwanted signal generation and battery drain. As soon as the Talk button is released, it can be pressed again to resume transmission.
