Then you will hear voice prompt indicating the battery level. However, if you release the buttons as soon as the headset turns on, you will not hear the voice prompt for the battery level indication. 4.
20S 5 PAIRING THE 20S WITH BLUETOOTH DEVICES Before using the 20S Bluetooth headset with any of Bluetooth devices for the first time, you will need to pair them together. It can be paired with Bluetooth mobile phones, Bluetooth stereo devices such as MP3 players, or motorcycle specific Bluetooth GPS navigation, and with other Sena Bluetooth headsets. This pairing operation is only required once for each Bluetooth device.
20S 5.2 Second Mobile phone Pairing 5.3 Bluetooth Stereo Device Pairing 1. If the Bluetooth stereo device is integrated with the mobile phone such as smartphones, you don’t need to pair the 20S with it separately. When the 20S is paired with the mobile phone, it is also paired as a stereo music device. 2. If you have a stand alone Bluetooth stereo device, follow the pairing procedure separately. The procedure is the same as the procedure in section 5.1, “Mobile Phone Pairing”. Note: 1.
20S 5.4 Bluetooth GPS Navigation Pairing 5.4.1 GPS Pairing 1. Turn on the headset and press the Jog Dial for 6 seconds until the red LED is rapidly flashing and you hear multiple beeps. 2. Within 2 seconds, tap the Phone Button and hear the voice prompt, “Second mobile phone pairing”. Again within 2 seconds, tap the Phone Button and the LED turns to green flashing and the beeps turn to multiple mid-toned beeps. You will hear the voice prompt, “GPS pairing”. 3.
20S HFP GPS HFP + (A2DP) Mobile Phone Mobile Phone Pairing 20S GPS Pairing as Mobile Phone Note: English 5.4.2 GPS Pairing as Mobile Phone If a GPS is not only used for turn-by-turn voice instructions but also is your preferred Bluetooth stereo music source, you can pair the GPS to the 20S by following the simple procedures in “5.1 Mobile Phone Pairing”. However, since some GPS systems support mobile phone bridging over Bluetooth, you can pair the mobile phone to the GPS to use your mobile phone.
20S 5. If the pairing process is not completed within three minutes, the 20S will return to stand-by mode. The incoming audio from the two-way radio via SR10 is heard in the background while having an intercom conversation or a mobile phone call. You can listen to music, answer a mobile call, have an intercom conversation and use a two-way radio via the SR10 for group communication as shown in the figure below.
20S If you have a MP3 stereo music phone such as a smartphone, sometimes you may need to selectively use the 20S for A2DP stereo music only or for mobile phone handsfree only. These instructions are for advanced users who want to pair the 20S to their smartphones only with one selective profile: A2DP stereo for music or HFP for phone calls. If you have previously paired a mobile phone to the 20S, you must clear the previous paring list on both devices; the mobile phone and 20S.
S 7 MOBILE PHONE CALL MAKING AND ANSWERING 7.1 Mobile Phone Call Making and Answering 1. When you have an incoming call, simply tap the Phone Button or the Jog Dial to answer the call. 2. You can also answer the incoming call by loudly speaking any word of your choice if Voice Activated Phone Answering (VOX Phone) is enabled, unless you are connected to intercom. 3.
20S (1) Last number redial (4) Speed dial 3 (2) Speed dial 1 (5) Cancel (3) Speed dial 2 4. After selecting the last number redial menu, you will hear a voice prompt saying “Last number redial”. Then, to redial the last phone call number, tap the Phone Button. 5. To call one of the speed dials, rotate the Jog Dial clockwise or counter-clockwise to navigate between the menus until you hear a voice prompt saying “Speed dial (#)”. Then, tap the Phone Button. 6.
20S a. To answer the phone call and stop the intercom conversation, tap the Jog Dial or the Phone Button. The VOX Phone feature does not work if you are connected to intercom. When you hang up the phone call, the intercom will automatically be recovered. b. To reject the phone call and stay on the intercom conversation, press the Jog Dial for 2 seconds until you hear a beep.
20S 3. To track forward or track back, rotate while pressing the Jog Dial clockwise or counter clockwise. Note: Bluetooth music is available only when the MP3 port remains open. Please make sure the audio cable is unplugged from the clamp unit to play music by Bluetooth. 2. To play or pause music, press and hold the Jog Dial for 1 second until you hear a double beep. 8.
20S 4. To track forward or track back, rotate while pressing down the Jog Dial clockwise or counter clockwise. 5. To terminate music sharing, press and hold the Jog Dial until you hear triple beeps and you will hear a voice prompt saying “Music sharing off”. Please refer to chapter 15 for more information on intercom connections. Note: 9 GPS NAVIGATION If you pair a Bluetooth GPS to the 20S as described in section 5.
20S As described in section 5.5, you can use a two-way radio and the 20S Bluetooth intercom simultaneously by using the Sena SR10, a Bluetooth Two-way Radio Adapter, along with the 20S. Incoming audio from the two-way radio will not interrupt an intercom conversation but is heard in background. This is useful when you have an intercom conversation with a passenger on the back seat and use a two-way radio for group communication with other motorcycle riders.
20S 11 FM RADIO 11.1 FM Radio On / Off To turn on the FM radio, press and hold the Phone Button for 2 seconds until you hear a mid-tone double beep sound. You will then hear a voice prompt saying “FM on”. In order to turn off the FM radio, press and hold the Phone Button for 2 seconds until you hear a voice prompt saying “FM off”. When you power off, the 20S will remember the last station frequency. When you power it on, the last station frequency will be playing. 11.
20S 11.6 Region Selection "Scan" is the function that automatically searches station frequencies, starting from the current frequency and up. To use the scan function, please follow the procedures below: 1. Double tap the Phone Button. Then the current station frequency moves upward to find other station frequencies. 2. If the tuner finds a station, it stays at the station frequency for 8 seconds, then scanning to the next station frequency. 3.
20S 12 AMBIENT MODE You can hear the ambient sound outside of your helmet by activating the Ambient Mode. To activate the Ambient Mode, press twice the Ambient Mode Button which is placed on the bottom of the clamp unit. To deactivate the Ambient Mode, press twice the Ambient Mode Button again. Ambient Mode Button Note: The ambient mode has higher priority than mobile phone, so you cannot make or answer phone call, listen to music, or have an intercom conversation if the Ambient Mode is activated.
