Figure 1. The push to talk (PTT) and volume (VOL) switch on the right side of speaker box allows the passenger to talk over the intercom or transmit over the CB as well as to raise or lower the rear headset volume.

Figure 1. Passenger Controls
NOTE
The passenger VOL switch affects only the passenger headset. The hand grip mounted AUDIO switch is the master volume control, and used in conjunction with the FADER, affects both the rider and passenger speaker volume.
Rider and passenger headset volume cannot be adjusted at the same time. Whoever has first use of their respective volume control has priority. With regard to stereo receiver tuning, radio band selection, CD track selection or other functions, simultaneous use of front and rear MODE SEL switches may cause operation to be suspended until either rider or passenger controls are released.
