Frequently Asked Questions

To power on the headset, press the Center Button and the (+) Button at the same time for 1 second.

When powering off the headset, tap the Center Button and the (+) Button at the same time until the red LED appears briefly and the headset turns off completely while hearing descending beeps.

You can charge the SRL2 by connecting the supplied USB power & data cable into a computer’s USB port or USB wall charger. You can use any standard micro-USB cable to charge the SRL2. The 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.

WARNING
When charging the battery, use only the approved charger provided by the manufacturer. Use of a non-approved charger may cause fire, explosion, leakage, and other hazards which may also reduce the life time or performance of the battery.

CAUTION
Please make sure to take off your SRL2-installed helmet while charging.
The headset automatically turns off during charging.

Checking the Battery Level

You can check the battery level in two different ways when the headset is powering on.

LED Indicator

When the headset is powering on, the red LED flashes rapidly indicating the battery level.

4 flashes = High, 70~100%
3 flashes = Medium, 30~70%
2 flashes = Low, 0~30%

Voice Prompt Indicator

When you power on the headset, press and hold the Center Button and the (+) Button for more than 6 seconds until you hear three, high-toned beeps. 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 of battery level indication.

You can raise or lower the volume by tapping the (+) Button or the (-) Button. The volume is set and maintained independently at different levels for each audio source even when you turn off and on the headset. For example, once you set the volume for mobile phone hands free, it will not change even if you adjust the volume for your Bluetooth MP3 music. So you can always maintain the preferred optimum volume level for each audio source.

WARNING Use of the product at a high volume for a long period of time may damage your eardrums or hearing ability. Keep the volume at a modest level to prevent damage.

3. Search for Bluetooth devices on your mobile phone. Select the Sena SRL in the list of the devices detected on the mobile phone.

4. Enter 0000 for the PIN. Some mobile phones may not ask for the PIN.

5. The mobile phone confirms that pairing has been completed and the SRL is ready to use. You will hear a voice prompt from the SRL saying “Your headset is paired”.

6. If the pairing process is not completed within three minutes, the SRL will return to stand-by mode.

1. Turn on the headset and press the Center Button for 12 seconds until you hear high-toned double beeps. You will hear a voice prompt saying “Configuration menu”.

Note:

1. If you are using second mobile phone connection and you have an incoming call from the second phone during the call of the first phone, then you may still receive the call from second phone. In this case, the call from the first phone is on waiting mode. If you end a call, then it will automatically guide you to the first phone call.

2. If you are using second mobile phone connection of mobile phone and GPS, you may not be able to listen to the GPS voice instruction during the phone call.

The Bluetooth audio device must be paired with the SRL. The SRL supports the Audio/Video Remote Control Profile (AVRCP), so if your Bluetooth audio device also supports the AVRCP, you can use the SRL to remotely control music playback. Not only can you adjust the volume but you can also use functions such as play, pause, next track and previous track. If the Audio Multitasking feature is enabled, you can listen to music while having an intercom conversation.

The two SRL2 headsets A and B are paired with each other for intercom conversation. If the pairing process is not completed within one minute, the SRL2 will return to stand-by mode.

4. You can pair with up to nine other headsets. To pair with more headsets such as A and C, A and D, and more, simply follow the same procedure as above.

5. The intercom pairing queue is ‘Last-Come, First-Served’. If a headset has multiple paired headsets for intercom conversations, the last paired headset is set as first intercom friend. The previous intercom friend becomes second intercom friend, and third intercom friend.

 

Note:

1. For example, after the pairing procedures listed above, headset D is the first intercom friend of headset A. Headset C is the second intercom friend of headset A, and headset B is the third intercom friend of headset A.

Start Multi-way Intercom

You can have multi-way intercom with up to seven other SRL2 users by creating an intercom chain. Both the head and the tail of the chain can add new participants.

For example, if you have a three-way intercom set up, the new participant (D) can be added to either (B)-the head, or (C)-the tail. If (D) were added to (C), then (D) becomes the new tail of the chain. If (D) were added to (B), then (D) becomes the new head. In this way, an intercom chain can hold up to a total of eight people.

Please note that each participant’s intercom friends are the ones adjacent to each other.

Note:

To have multi-way intercom with more than four participants, you must enable Eight-way Intercom. 

End Multi-way Intercom

You can completely get out of the multi-way intercom or just disconnect a part of the chain.

1. Press the Center Button for 5 seconds until you hear double beeps to terminate multi-way intercom. It terminates the intercom connections between you (A), and all participants in the chain.

2. Single tap or double tap the Center Button to disconnect intercom connection between one of the two intercom friends. A single tap will disconnect the intercom connection between you (A) and (B). Rest of the connection of the chain will be preserved. Likewise, double tap will disconnect the intercom connection between you (A) and (C), while preserving rest of the connections.

Eight-Way Intercom (Default: Disable)

You can enable or disable Eight-way Intercom through the Sena Device Manager or the Sena Smartphone App. Disabling the Eightway 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.
