|Q||Are the Sena headsets going to be worn by experienced skippers and crew?|
|A||Yes, professionals especially will know the advantage and benefits of quick and clear communications between the helm and the crew. Anything that makes it easier to carry out efficiently the numerous tasks around a boat can only be considered to be an added advantage in terms of team work and safety to both the crew and to the vessel.
|Q||How do you pair two headsets?|
|A||Turn on the two headsets (A and B) that you would like to pair. Then hold down the jog dial button on the headset 'A' for 5 seconds until the red LED light flashes rapidly. Then press and hold down the jog dial of the headset B for 5 seconds until the red LED light flashes rapidly. Then tap either the jog dial button of either A or B headsets and wait until both headsets LED lights turns blue- the intercom pairing is then complete.
|Q||How many headsets can be paired?|
|A||The manufacturers suggest no more than four in total in order to preserve the quality of the sound distribution.
|Q||How does the intercom work?|
|A||Assuming that the headsets are switched on and are in standby mode; then if person 'A' wants to speak to person 'B' they tap the button on the side of their headset which opens up the intercom channel. The channel then remains open allowing full and free communication without pushing any other buttons until the channel is to be closed. For three or more connections please see the Sena manual for instructions.
|Q||Are there any wires connected to the headset and is there a separate battery pack?|
|A||No, there are no wires to get entangled with and no battery pack; the battery is contained within the headset.
|Q||Is the Sena intercom voice activated?|
|A||No, The Sena intercom has a dedicated channel that once opened allows the free flow of conversation. Voice activated systems are considered by some to be somewhat frustrating as the time delay for the persons voice each time to activate the channel can result in the first few words being lost.
|Q||Do I need to keep a note of the serial number?|
|A||Yes, you will need the serial number to register your headset with Firmware to obtain the free upgrades; we suggest you do this sooner rather than later. You may need the serial number again in the future so keep a note of the serial number with the headset.
|Q||Are they comfortable to wear?|
|A||Yes, we have personally worn them for over three hours just to check this point out. Other reports we have seen tell of people wearing them for a journey that lasted nearly 8 hours.
|Q||Can you hear what is going on around you when you are wearing the headphones?|
|A||Yes, when testing them we could still have conversations with people not wearing the headsets and although the noise cancellation system helps reduce constant back ground noise like engines or machinery etc. You can still hear other noises or if the background noise changes.
|Q||Is there an online manual?|
|A||Yes, you can download the quick start guide here, or a full version of the manual is downloadable at
|Q||Can I wear a hat while wearing the headsets?|
|A||Obviously it depends on the style and texture of the hat but most soft hats can be worn including most coat hoods.
|Q||Can I use the headset with my mobile phone?|
|A||As long as your mobile phone has Bluethooth connectivity. For full details and instructions please see the manual.
|Q||Can I use the headsets to listen to audio?|
|A||Yes, there is an audio cable provided which fits into a socket on the headset.
Also if your Audio equipment is Bluetooth compatible then see the manual for linking it to the headset.
|Q||Are the headsets waterproof?|
|A||No they are water resistant. When testing them in adverse weather conditions we tended to wear our hoods to keep both ourselves and the headsets dry.
|Q||How much do the headsets weigh and are they comfortable to wear?|
|A||They are comfortable to wear and are difficult to dislodge. The approximate weight according to the manufacturer is 112 gm or 0.25 lbs (4 oz)
|Q||Is there a volume control?|
|A||Yes, the volume control is easy to use and is located on the side of the headphones. It is possible to set up the volume for each of the different operations for which you might be using the headset.
|Q||How do you charge the headsets and how long does one charge last?|
Your headsets are fitted with lithium-polymer batteries and they take approximately 2½ hours to fully charge and this will provide up to 10 hours standby time and 7 hours talk time.
Like all modern electronic equipment it is important to look after the batteries and the following points may be of help.
When charging your headsets always use the cable provided with your headset and attach it to a suitable USB plug that has a maximum output of 5 Volts and between 500mA and 1000mA (0.5 and 1 amp). Mobile phone USB plugs were considered suitable but recent changes means that many such plugs have a much greater output and could damage your batteries. A 12 volt circuit can be used like a car cigarette lighter or USB terminal on a computer as long as they do not have an output greater than 1000mA (1 amp). If using a dual USB plug with an output of 5 volts and 1000/2000mA then charge two headsets at the same time. For example charging using a plug with an output greater than 2 amps will over heat the batteries and can cause damage and shorten the battery life.
When charging the batteries they will not always need to be charged for the full 2½ hours so when the blue light comes on it means that the batteries are fully charged and the headsets can then be removed from the power source.
The headsets are designed for regular daily use but avoid the temptation of too frequently recharging your headsets as this can also shorten the battery life. For example, a 10 day trip where the headsets were worn for going into and leaving 5 marinas was all done on a single charge; the total time the headsets were in use was just over 3 hours.
Occasionally let your headsets fully discharge before recharging; do not leave your headsets discharged for prolonged periods of time, especially over the winter, as the software requires a residual amount of power.
Avoid leaving your headsets in direct sunlight when not in use. Even in the UK an area for example behind a windscreen can exceed 112 degrees, enough to start cooking any electronic device.
|Q||Which microphone is the best one to use?|
|A||This is a matter of choice and depends where and when you are using the headset. We found the boom microphone suited us best. In noisy or windy conditions the boom microphone provides the best solution.
|Q||What are the rubber headset ear covers for?|
|A||They should be fitted to protect the headphone speakers from perspiration or moisture in adverse conditions. The headset is water resistant only.
