How does the Lightspeed Link™ system work?
Lightspeed Link is comprised of two wireless technologies: an analog signal carries the pilot's voice to the intercom while a digital signal carries communication to the headset. This patent-pending blend of technologies avoids the drawbacks of other wireless platforms to deliver the clearest, most reliable wireless communication available in an aviation headset.

What makes this better than Bluetooth or WiFi?
Bluetooth and WiFi signals travel too slowly and would produce an unacceptable echo effect in sidetone, negatively affecting clarity and the enjoyment of flight.

Do I need to do anything to "pair" my headset to the panel interface?
The Tango headset and panel interface are paired at the factory, so all you need to do is turn them on.

Does the LEMO / panel-powered version of Tango auto on with the master switch?
Yes, the LEMO / panel-powered version of the Tango panel interface does automatically turn on when aircraft power is sensed. The Tango headset, however, still operates on a battery and must be turned on manually.

Why do I hear odd noises when I have more than one Tango headset operating in the same aircraft?
The most likely cause is two or more headset/panel interface pairs set to the same channel. Make sure all headset/panel interface pairs are set to their own unique channel. See page 14 of the Tango User Guide to learn about using multiple Tango headsets.

Why does the ANR turn off when I plug in the backup cable?
When you use the backup cable, all circuitry not essential to communication is disabled and the headset operates in passive noise reduction mode. Lightspeed engineers assumed the backup cable would only be used when wireless communication was unavailable. This is almost always due to a dead battery, but in case there is another cause, this feature prevents any additional anomalies that might distract the pilot.

Is it better if the battery goes to zero before charging or should it be topped off after each use?
Lithium ion batteries don't exhibit the memory effects that Ni-Cad batteries used in older technology do. We recommend charging your battery before each flight, regardless of its state of depletion (just as you charge your phone at night).

What is the best charge state if the battery will be stored for an extended period?
It is best to store your battery in a partially discharged state. Storing in a fully charged state could slightly decrease the useful life of the battery.

Could I leave the battery plugged into the charger when not in use?
Leaving the battery charging for extended periods of time (several weeks or months) could result in a slight reduction in its useful life. Leaving it charging for a few days will not likely have any negative effects.

How does the ANR in this headset compare to your other models?
The noise reduction capability of Tango is equal to or better than any competitive headset on the market. See our Reviews & Testimonials page for first hand accounts.

What causes a warbling noise in the ear cup when the headset is turned on?
If your ear is not entirely inside the cup, with a tight seal, air can seep in and cause the ANR to compensate for uneven internal cup pressure, creating a rapid oscillation in pressure that we experience as a warbling noise or rapid "thumping." Make sure you have a proper fit and the ear seals are in good condition.

My Bluetooth audio is dropping out, how can I fix this?
Try moving the Bluetooth source (phone or other device) to a location closer to the panel interface. Also, if your panel interface is inside a pocket or box, try placing it on the outside. We have included a steel mounting hook and multiple MOLLE loops to make it easy to find a convenient location.

Where is my product serial number?
The serial number can be found on the outside of the outer box and on the headset behind the battery access door, in the battery compartment. Look for a small, white, bar-coded sticker.

Why is there a "Euro" version?
This is because the Euro Zone regulations allow for different available wireless frequencies than U.S. regulations. Find which version of the headset that is right for you here.
What happens if I fly with the Euro version in a non-Euro Zone country?
Nothing. It will perform normally.
