Charge the wireless headset by connecting the supplied USB power & data cable into a computer USB port or USB wall charger. You can use any standard micro-USB cable to charge. The Light Emitting Diode (LED) turns red while the headset is charging and turns blue when it is fully charged. It takes about 2.5 hours to be completely charged.

Press the Jog Dial and the Phone Button at the same time to power the headset either on or off. When powering on the headset, press the Jog Dial and the Phone button at the same time until the blue LED appears while hearing the ascending beeps. When powering off the headset, press the Jog Dial and the Phone Button at the same time until the red LED appears briefly and the headset turns off completely while hearing descending beeps.

Before using the wireless headset with any Bluetooth® devices for the first time, you will need to pair them together. For example, it can be paired with Bluetooth mobile phones, Bluetooth stereo devices such as MP3 players, or motorcycle specific Bluetooth Global Positioning System (GPS) navigation, and with other Boom! Audio Bluetooth headsets. This pairing operation is only required once for any Bluetooth device. The headset remains paired with the devices and automatically reconnects to them when they are within range. You will hear a high tone single beep and a voice prompt when the headset connects to the paired device automatically:

When a headset is paired to the motorcycle, it will say Your Headset is Paired, Boom Audio Connected. After this initial pairing, every time the headset connects to the motorcycle you will hear Boom Audio Connected.

When a headset is paired to a phone, it will confirm the pairing by saying Your Headset is Paired.. After this initial pairing, every time the headset reconnects to the phone it will say Phone Connected.

Please read the Sena User’s Guide for information pertaining to the wireless headset to headset intercom set up and usage.

The 12 configuration modes can be accessed though the Boom! Box Infotainment system. Configuration options are only available for Harley 20S and 20S EVO headsets. They will not appear for non-Harley headsets or the SPH10.

Select Home > Setup > Wireless Headset > Manage Rider or Passenger Headset > Config to manage headset configurations.

Smart Vol. Control: Smart Volume Control automatically changes the level of the speaker volume based on the level of the environmental noise. When it is disabled, volume is controlled manually. You can enable it by setting the sensitivity to low, medium, or high. Smart Volume Control responds to smaller environmental noises as the sensitivity level becomes higher. This factory setting is disabled.

SideTone: Sidetone is the sound of your own voice as picked up by your headset’s microphone and reproduced in your own ear, by your own speaker. It helps you to naturally speak at the correct level according to varying helmet noise conditions. If this feature is enabled, you can hear what you are speaking during an intercom conversation or a phone call. This factory setting is disabled.

Voice Prompt: You can disable voice prompts, but the following voice prompts are always on:

Adv. Noise Control: When Advanced Noise Control is enabled, the background noise is reduced during an intercom conversation. When it is disabled, the background noise is mixed with your voice during intercom. This factory setting is enabled.

Motion Sensitivity: Motion Sensor Sensitivity determines the sensitivity when you double tap on the surface of the Boom! Audio 20S EVO to enter voice command mode. The factory setting is low, but you may change it to high, or disable the feature.

VOX Phone: If this feature is enabled, you can answer incoming calls by simply saying a word loudly enough, unless you are connected to intercom. For example, when you hear a series of beeps for an incoming call, you can answer the phone by saying Hello or any other word loudly. However, the VOX Phone feature does not work if you are connected to the intercom. This feature is enabled from the factory but can be disabled through the configuration menu, Device Manager, or the Sena Smartphone App. If this mode is disabled, you have to tap the Jog Dial or the Phone Button to answer an incoming call.

HD Intercom: HD Intercom enhances the two-way intercom audio from normal quality to HD quality. HD Intercom will become temporarily disabled when you enter into a multi-way intercom. If this feature is disabled, the two-way intercom audio will change to normal quality. This factory setting is enabled.

Audio Multitasking: Audio Multitasking allows you to have an intercom conversation while simultaneously listening to music, FM radio, or GPS instructions. The overlaid audio is played in the background with reduced volume whenever there is an intercom conversation and will return to normal volume once the conversation is finished. If this feature is disabled, any incoming or outgoing intercom will interrupt your audio channel. This factory setting is enabled.

INT-Audio Sensitivity: INT-Audio Sensitivity changes the sensitivity level at which the headset detects you are speaking and turns on sidetones. Level 1 is the lowest sensitivity and you will have to speak very loud. Level 10 is the most sensitive and will trigger with very little sound. Pending on riding conditions this may need to be adjusted due to ambient noise. The factory setting is 6.

Nav. App Support: When Audio Multitasking is enabled, your smartphone’s GPS application reduces in volume whenever there is an ongoing intercom conversation. To listen to your smartphone’s GPS navigation clearly without this volume reduction, enable Navigation App Support. This factory setting is disabled.

Eight-way Intercom: Disabling the Eight-way Intercom optimizes the intercom performance for a small group up to four participants. Enabling the Eight-way Intercom optimizes the intercom performance for a larger group up to eight participants. This factory setting is disabled.

FM Station Guide: When FM Station Guide is enabled, FM station frequencies are given by voice prompts as you select preset stations. When FM Station Guide is disabled, the voice prompts on FM station frequencies will not be given as you select preset stations. This factory setting is enabled.

See Figure 19. When the wireless headset is properly paired it will confirm:

When the Boom! Audio 20S EVO is not working properly or is in faulty status for any reason, you may reset by pushing the pin-hole reset button at the back of the headset main unit. Insert a paper clip into the reset pin-hole and press the reset button for a second with light pressure. The Boom! Audio 20S EVO will be switched off, and you have to turn the system back on and try again. However, this will not restore the headset to factory default settings.
