Auto Shut-Off
The Stratus 50-D contains noise-sensing features which measure ambient noise
levels. When these ambient noise levels are low for 5 to 7 minutes continuously,
the headset automatically shuts off. This feature will prolong battery life and
prevent discharge of batteries if the headset is accidentally left on after usage.
Cellphone / audio interface
The Stratus 50-D includes a unique amplified interface allowing for the
connection of a cellular telephone and an audio input simultaneously. This
setup allows for all of the equipment to be set up before take-off eliminating
the need to re-configure cords and equipment when operating the aircraft.
The other unique feature of this interface is the ability to obtain power from the
aircrafts communications system. This feature results in increased battery life
for the ANR system while keeping the benefits of an amplified interface. By
amplifying the inputs, the Stratus 50-D allows the user to adjust volume level
at the headset contributing to the ability to not need re-configuring while in
flight.
The Telex Stratus 50-D cell phone / audio interface has been
designed to function with the widest array of cellular telephones
and portable audio devices. There are cell phones and audio
devices on the market not designed to industry physical and
electrical standards. These devices are not guaranteed to
function properly with the Stratus 50-D headset.
Please see the Telex website for additional information and cell phone
compatibility lists.

Microphone Bias Voltage Requirements
The boom microphone operates on a voltage of 8-16 VDC. Output impedance is
50 ohms (Designed for radio input impedances from 50-600 ohms). If you are
uncertain whether your avionics equipment meets this requirement, consult the
avionics equipment manufacturer.
The cellular telephone / auxiliary audio interface of the Stratus 50-D relies on this
same microphone bias voltage for operation. If less voltage / higher impedance
is normal in your system, this interface may not operate properly. If unusual or
unacceptable performance of the boom microphone or cellular / audio interface
is discovered, the cellular /audio interface should be disabled using the
accessory mute (described later in this manual.)
