5. Operating Instructions
5.1 Powering On/Off and Volume Adjustment
Rotate the power/volume knob (located on the top of the radio, see Image 3.3) clockwise to power on the radio. Continue rotating clockwise to increase the volume. Rotate counter-clockwise to decrease volume and fully counter-clockwise to power off the radio.
5.2 Selecting a Channel
Rotate the channel selector knob (located on the top of the radio, see Image 3.3) to choose one of the 16 available channels. The selected channel number is indicated on the knob.
5.3 Transmitting and Receiving
- Receiving: When the radio receives a signal, the LED indicator will illuminate, and you will hear the audio through the speaker.
- Transmitting: To transmit, press and hold the Push-To-Talk (PTT) button on the side of the radio (see Image 3.2). Speak clearly into the microphone, holding the radio approximately 2.5 to 5 cm (1 to 2 inches) from your mouth. Release the PTT button to stop transmitting and return to receive mode.
5.4 High/Low Power Switch
The TC-320U-1 allows you to switch between high and low power output. Refer to your radio's specific controls for the location of this switch, typically a dedicated button or a programmable function. Using low power conserves battery life when communicating over short distances.
