What to do if my Standart Horizon HX40 cannot output sound?

If your Standard Horizon Transceiver isn't outputting sound when you press and hold the [SQL/VOL] key, there could be a couple of reasons. First, check if the battery is low and charge it if needed. Also, the audio volume level might be too low. Try pressing the [?] key until you hear background noise.
