available on the website www.factem.com.
• Always maintain a distance of at least 10cm between the eardomes and
pacemakers or implantable debrillators (ICDs) in the cockpit because these
products generate permanent magnetic elds.

• Keep the product, accessories and packaging parts out of reach of children to
avoid ingestion.
• When active noise reduction (ANR) is activated, typical aircraft sounds (for
example engines, propellers, alarms etc.) may seem dierent. Before using the
headset, verify that with ANR activated these sounds can be heard and recognised.
Adjust the dashboard volume to a level which allows these audio signals to be
heard properly.
• This product is capable of producing acoustic pressure greater than 85dB (A). In
many countries, 85dB (A) is the maximum legally admissible level for continuous
exposure to sound during the working day. Do not listen at an elevated volume
for long periods of time, in order to avoid hearing damage.
