Frequently Asked Questions

When powering 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 SRL 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 SRL. 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.

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.

Volume Adjustment

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 handsfree, 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.

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 SRL by following the simple procedures in section 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. When you do this, the SRL thinks the
GPS is a mobile phone so you can no longer pair your mobile phone
to the SRL directly. Please refer to the user’s guide of your GPS for
details.

Start Multi-way Intercom

You can have multi-way intercom with up to seven other SRL 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.

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.

 

You may make a four-way Universal Intercom connection with a couple of different configurations, 1) three SRLs and one non-Sena Bluetooth headset or 2) two SRLs and two non-Sena Bluetooth headsets.

You may have a couple of other four-way Universal Intercom configurations, 1) your headset (A), a non-Sena Bluetooth headset (B), another SRL (C), and a non-Sena Bluetooth headset (D), 2) your headset (A), a non-Sena Bluetooth headset (B), and two other SRL headsets (C and D). You may make the four-way Universal Intercom call the same way as a normal four-way intercom call.

1. You (A) may start an intercom conversation with the non-Sena Bluetooth headset (B).

2. The other SRL (C) may join the intercom by making an intercom call to you (A).

3. The non-Sena Bluetooth headset (D) may join the three-way intercom by making an intercom call to the SRL (C).

4. Now two SRL headsets (A & C) and two non-Sena Bluetooth headsets (B & D) are connected with the four-way Universal Intercom.

You may disconnect a four-way Universal Intercom using the same
way as you do in a normal four-way intercom.
