Pilot System FAQ

Relai System FAQ

Where is the battery in a Micro System headset?

The battery is part of the headset headband. The reason that the battery is manufactured into the headband – rather than being in one of the ear-cups – is so that it does not interfere with the noise attenuation properties of the headset. (Top)

Is the battery rechargeable?

Yes, the battery is made from Nickel Metal Hydride cells and is rechargeable. (Top)

How many years does the battery last?

The battery has a shelf-life of at least ten years and, providing it is looked after, can be recharged at least one thousand times. (Top)

Can the battery be replaced?

If the battery does ever need replacing, it is a simple matter for our service department to change the headband assembly. (Top)

How long does the battery last after each charge?

The headset will provide at least fifty hours use from a single charge. If the headset volume is correctly adjusted the headset will work for up to eighty hours. (Top)

How is the battery charged?

Each headset is plugged into a wall charger and charged using mains electricity. (Top)

Is there a memory effect?

No, the battery is made from Nickel Metal Hydride which does not have a memory effect. (Top)

How long does it take to charge the battery?

It is not necessary to charge a headset for more than sixteen hours. (Top)

Can the battery be overcharged?

We do not advise leaving a headset on charge for more than forty-eight hours. However, it is very difficult to damage a headset when using the correct Lynx charger. (Top)

How do I know it the battery is about to run out?

Immediately before the headset runs out of power the sound in the headset becomes distorted. This provides approximately one hours warning that the battery is about to run-out. (Top)

Is it possible to damage the battery?

The only sure way to damage the headset batteries is to leave the headsets to go flat and to store them in a flat condition. Storing the headsets in a cold environment will increase the rate at which the headsets self-discharge and will exacerbate this problem. (Top)

How do I keep the battery in good condition?

Recharge the headsets regularly – even when they are not being used – and store them at room temperature. (Top)

Is the headset 'Active Noise Reduction' (ANR)?

No, Lynx Avionics' headsets are not 'Active Noise Reduction'. The reason for this is that active systems do not work well with a wide band of noise and, as such, they are not very effective when used with two stroke or other high revving engines.

Lynx Avionics' headsets work by using a very effective noise attenuating ear-cup design coupled with a very effective noise cancelling microphone. (Top)

Can I use Micro System headsets in General Aviation aircraft?

Micro System headsets can be converted to General Aviation twin-jack plugs using a plug-in 'Twin Jack Adapter'. (Top)

Can I use Micro System headsets with other manufacturers headsets or intercoms?

Lynx Avionics does not manufacture adapters to allow Micro System headsets to connect to other makes and models of intercom. Some other manufactures do make this type of adapter so that their products can be used with Lynx equipment. (Top)

Can I use a Mobile Telephone with Micro System headsets?

Yes, a mobile telephone can be connected to the equipment using an 'Audio Adapter' and a 'Mobile Telephone Lead'. (Top)

Can I use Micro System headsets with a radio?

A range of radio interface units are available to connect Micro System headsets to virtually all available radios. (Top)

Can I use any radio with the Micro System?

There are many different electronic standards used by radio manufactures. For this reason, Interface units must be specially configured to work with each particular make and model of radio. Lynx interface units have internal setting switches which allow them to be changed easily between the common types of radios. (Top)

Can I change the radio settings?

While it is not difficult to change the radio settings, it is always preferable if this work is carried-out by the experienced engineers at Lynx Avionics. Lynx provides a free reconfiguration service which includes full testing and shipping. (Top)

Can I connect to my own P.T.T. switch?

A 'PTT Connector and Lead' is available which makes it very easy to connect any existing 'Normally Open Switch' to Lynx radio interface equipment. (Top)

Can I play music through the headsets?

It is possible to play music through the headsets by using an 'Audio Adapter' and an 'Audio Input/Output Lead'.

It is also possible to play music through the headsets by using a 'Radio/Power Interface Unit' and an 'Audio Input/Output Lead'. (Top)

Can I record the intercom audio?

It is possible to record the intercom audio by using an 'Audio Adapter' and an 'Audio Input/Output Lead'.

It is also possible to record the intercom audio by using a 'Radio/Power Interface Unit' and an 'Audio Input/Output Lead'

This will work with both tape recorders and video cameras. (Top)

Will the Radio/Power Interface Unit work without a 12Volt supply?

Yes, if the interface is not connected to 12Volts, or if the power fails for any reason, interface unit draws its power from the headsets. (Top)

Do I need to charge the headsets if I use a Radio/Power Interface Unit?

Yes, unless you fly almost every day, it is still a good idea to charge the headsets from time-to-time. (Top)

Can I use Pilot System headsets in any aircraft?

Pilot System headsets are designed to connect to standard aviation intercom systems and will work in any light aircraft. (Top)

Can I use Pilot System headsets with other makes and models of headset?

This is normally possible but some times there are incompatibilities between different makes and models of headset. To obtain the best performance, it is always preferable to use two or more Lynx headsets. (Top)

Is there a NATO version of the Pilot System headset for use in helicopters?

Yes, the latest model of Pilot System headsets has an interchangeable headset lead and leads are available with either twin-jack plugs, US NATO jack plug or UK NATO (Euro) jack plug. (Top)

Are Pilot System headsets as good a Micro System headsets?

Pilot System headsets are very similar in construction to Micro System headsets and they offer very high performance – especially in open-cockpit aircraft. However, Pilot System headsets are always used with a third-party intercom which is never as good as the intercom built-in to Micro System headsets. (Top)

Can I connect two Relai System headsets together?

No, Relai System headsets are only intended for solo use and they do not contain an intercom. (Top)

Can I use any radio with a Relai System headset?

There are many different electronic standards used by radio manufactures. For this reason, Relai System headsets must be specially configured to work with each particular make and model of radio. The headsets are configured using a small plug-in module which allows them to be changed easily between the common types of radios. (Top)

Can I change the radio module?

Yes, different modules are available and they can be easily changed without any previous experience or specialist knowledge. (Top)

Can I use a separate PTT switch?

Yes, two Press-To-Transmit switches are incorporated into the headset but there is also a connector which allows a separate switch to be connected. (Top)

Can I hear myself talk when I transmit on the radio?

This depends on the radio that you are using: some radios provide side-tone and some do not. If it is important that you can hear yourself talk, when you use the radio, you may wish to consider a Micro System headset which always provides side-tone. (Top)

Are Relai System headsets as good a Micro System headsets?

Relai System headsets use the same components as Micro System headsets and they provide the same level of noise attenuation and noise cancellation performance. (Top)
