5. Maagizo ya Uendeshaji
5.1 Kuwasha/Kuzima na Marekebisho ya Sauti
- To turn on: Rotate the Power/Volume knob clockwise until a click is heard and the display illuminates.
- To turn off: Rotate the Power/Volume knob counter-clockwise until a click is heard and the display turns off.
- To adjust volume: Rotate the Power/Volume knob while the unit is on. Clockwise increases volume, counter-clockwise decreases it.
5.2 Uchaguzi wa Chaneli
- Use the Up/Down arrow buttons to select your desired communication channel (1-47).
- Ensure all transceivers in your group are set to the same channel for communication.
5.3 Kutuma na Kupokea
- Ili Kusambaza: Press and hold the PTT button. Speak clearly into the microphone (located near the speaker grille). Release the PTT button when finished speaking.
- Ili Kupokea: Ensure the PTT button is not pressed. The transceiver will automatically receive signals on the selected channel.
