5. Use the channel buttons to ensure the correct channel is selected.
6. When receiving a valid signal, the LED will illuminate steady green, and audio will be emitted from the speaker or connected accessory.
7. To switch off, press and hold the on/off button (1) until the radio beeps and the LED/LCD extinguishes.

Transmitting

1. Perform steps 1 through 5 of "Switching On, Reception, and Switching Off".
