4. See Figure 6. Clean the clip mounting area with a mixture of 50 to 70% isopropyl alcohol and 30 to 50% distilled water. Allow to dry thoroughly. The adhesive clip will be secured to the lower portion of the fuel tank, so it will be covered by the seat.
a. Install the clip (4) on the wire harness. Do not remove the adhesive backer at this time.
b. Install the narrow end of the headset bracket (3) between the console molding strip and the console at the lower left corner of the console as shown.
c. Trim the adhesive patch (5) to the shape of the back of the headset plug (2), remove one side of backer and apply to the back of the connector plug to protect the tank from scuffing. Trim the adhesive patch to a 12 x 6 mm ( x  in) rectangle. Remove one side of the backer and apply to the underside of the bracket as shown.
d. Position the headset connector facing up and use the wider end of the bracket to secure the flat portion of the headset connector as shown.
e. Remove the backer from the other side of the patches to secure the bracket to the connector and connector to the fuel tank.
f. Install the adhesive back clip (4) as shown. Remove the adhesive backer from the clip and install the clip onto the fuel tank where it will be covered by the seat.
NOTE
Allow AT LEAST 24 hours after applying the clip before exposing the area to vigorous washing, strong water spray or extreme weather.
5. Install the weather cap assembly on the rider headset connector by installing the locking ring inside the flip cap.
6. Secure all wiring with cable straps as needed. Check the motorcycle to verify that the wire harness does not interfere with the steering, suspension travel or any other moving parts of the motorcycle.
7. Refer to the service manual to install all the components removed in REMOVAL Step 1.

FEATURES OF ADVANCED AUDIO RADIO
Understanding Speaker/Volume Features
A three-position speaker switch is:
  • Standard on FLHTCU, FLHTCUTG and FLHTK models.
  • Included in kits 77107-09 and 77108-09A.
Basic points to remember:
  • The speaker switch controls the location through which music and bike-to-bike communications are heard (speakers or headsets).
  • Rider-to-passenger communications ("Intercom") are ALWAYS heard through the headsets, regardless of switch position.
In the down position (nearest rider), audio and bike-to-bike communication will be heard through the vehicles speakers. Intercom will come through the rider and passenger headsets.
In the middle position, audio will be heard through the vehicle speakers. Bike-to-bike communication and intercom will come through the rider and passenger headsets.
In the up position (furthest from the rider), audio, bike-to-bike communication and intercom will come through the rider and passenger headsets.
Volume Settings
Basic points to remember:
  • There are separate volume settings for speaker and front and rear headsets.
  • There are separate volume settings for music, intercom, and bike-to-bike (CB).
  • Getting these volume settings out of proper adjustment is likely the second-most confusing/frustrating aspect a customer could encounter.
Volume settings for audio, communication, and intercom are all independent and all adjusted by using the AUDIO +/- switch on the rider left hand control or passenger PTT/VOL+/VOL- switch.
Audio (music) speaker volume can be adjusted by the RIDER ONLY while listening to music via speakers by pressing up or down on the audio button on the left hand control.
  • Note that a "Speaker" icon displays on screen.
Audio (music) headset volume can be adjusted by rider OR passenger independently while listening to music by pressing up or down on the audio button on the left hand control or passenger PTT switch.
  • Note "F" for front/rider and "R" for rear/passenger settings display on screen in headset mode.
Intercom volume can be found by pressing the INT button on the radio face. It can only be adjusted in INT mode.
  • Volume can be adjusted by rider OR passenger independently.
  • Note "F" for front/rider and "R" for rear/passenger volume settings displayed on screen .
  • Press the INT button again to return to normal music operation.
Bike-to-bike communication volume can be found by pressing the COM button on the radio face. It can only be adjusted in COM mode.
  • Volume can be adjusted by rider OR passenger independently.
  • Note "F" for front/rider and "R" for rear/passenger volume settings displayed on screen.
  • Press the COM button again to return to normal music operation.
  • The rider or passenger can press the PTT button to communicate with other motorcycles or vehicles equipped with a CB system.
Understanding Intercom Voice Activation
NOTE
This feature works with few problems when set up properly, but an be the biggest source of confusion and frustration for an inexperienced user.
VOX, Voice Operated eXchange, (a.k.a. "Voice Activation") is used to open and close the microphone when rider and passenger are using intercom to talk to each other while riding. When the microphone is "open", the music being played is muted slightly to become "background music" during conversation. Once the microphone closes, music volume returns to its previous setting.
This VOX sensitivity setting can be adjusted by pressing the intercom button on the radio face and utilizing the Mode +/- switch on the right hand control.
  • Turning the sensitivity down will require the rider and passenger to speak louder to start a conversation.
  • Turning the sensitivity up will open the microphone more easily, with lesser voice strength needed.
  • As road conditions change, highway vs. city streets, or as the wind changes, adjustments to VOX will likely be required, since the background noise is added to the spoken voice level to "break" the VOX setting and open the microphone.
NOTE
Music is muted (whether in speakers or headsets) whenever the VOX is opened for intercom use. Unexplained, intermittent music volume can often be due to VOX setting being set too sensitively for the current conditions, causing the microphone to open and "mute" the music intermittently.
