Intercom Pairing with Other Sena Devices
Establishing an intercom connection with another Sena device allows for rider-to-rider communication. To initiate pairing, both 20S units must be powered on and in intercom pairing mode – usually activated through a specific button combination (refer to the full user manual for details). The devices should be within close proximity, ideally within 10 meters.
Once in pairing mode, the devices will automatically search for each other. Upon successful connection, a confirmation tone will sound, and the intercom channel will be established.

Troubleshooting Common Issues
Resolve pairing problems, audio quality concerns, and battery life issues with our guide. Find solutions for a seamless Sena 20S experience, maximizing functionality.
Device Not Pairing
Experiencing difficulty pairing your Sena 20S? First, ensure Bluetooth is enabled on both your Sena device and the target device (smartphone, GPS, etc.). Confirm the 20S is in pairing mode – typically activated by pressing and holding the power/intercom button until the LED flashes blue.
If pairing fails, try clearing the pairing list on both devices. On your smartphone, “forget” or “unpair” the Sena 20S. Then, restart both devices and attempt the pairing process again. Refer to the SmartSena App for guided pairing instructions. macOS users may need to re-pair after updating their operating system. Check for firmware updates, as outdated firmware can sometimes cause pairing conflicts.
Finally, ensure the devices are within close proximity during pairing – ideally within 3 feet. If issues persist, consult the Sena support website for further assistance.
Poor Audio Quality
Experiencing muffled, distorted, or intermittent audio with your Sena 20S? Several factors can contribute to this. First, check the volume level on both the 20S and the connected device. Ensure it’s not set too low or maxed out, which can cause distortion.
Verify the speaker mesh is clean and unobstructed. Debris can significantly impact sound clarity. Also, confirm a stable Bluetooth connection; interference from other devices can degrade audio quality; Experiment with different audio multitasking settings within the SmartSena App to optimize sound prioritization.
If using intercom, distance and environmental factors (wind noise) can affect clarity. Consider updating the firmware to the latest version, as updates often include audio performance improvements.
Battery Life Concerns
Is your Sena 20S battery draining faster than expected? Several factors influence battery performance. Active use of multiple features simultaneously – intercom, music, GPS – significantly reduces runtime. Ensure you’ve fully charged the device before each ride; incomplete charging impacts capacity.
Disable unused features like FM radio when not in use. Lowering the volume also conserves power. Check for firmware updates via the SmartSena App, as manufacturers often optimize power management in newer versions.
Extreme temperatures can affect battery life; avoid prolonged exposure to heat or cold. If the battery continues to deplete rapidly, contact Sena support for assistance.
Safety and Maintenance
Prioritize safety while using your Sena 20S. Always ensure clear communication doesn’t distract you from riding conditions. Regularly inspect the unit for any physical damage to the speaker, microphone, or housing. Clean the device with a soft, dry cloth; avoid harsh chemicals or excessive moisture.
Proper storage is crucial. When not in use for extended periods, fully charge the battery and store the 20S in a cool, dry place. Avoid disassembling the unit yourself, as this voids the warranty and may cause damage.
Follow all local laws regarding the use of communication devices while operating a vehicle. Responsible use ensures both your safety and the safety of others on the road.
