CB audio routing: CB audio can be routed to the speakers or the rider/passenger headsets. See System Settings → Speaker.

Adjusting CB volume (while on CB screen): Use rider volume controls to adjust speaker or rider headset volume. Use passenger volume controls to adjust passenger headset volume.

Adjusting CB volume (while not on CB screen): See Figure 1. While CB audio is being received, use the rider or passenger volume controls. If necessary, first reduce the squelch until CB audio breaks squelch, then adjust the volume. Raise the squelch to its original level.
