are switched on and located within range,
communication is effected between them
exactly as if they were connected via a
cable. When you have connected your
headset with your mobile phone, simply

answer a call.
If your phone supports voice-activated
calling, it is also possible to utilise this
function via the headset. The Ex-TRA BT
unit is par ticularly suitable for use with
the Ex-Handy 05 mobile phones from
ecom and the entire x.com series.
Even existing W-LAN networks can be
used for communication when utilised
in conjunction with our explosion-protected PDA i.roc.
The wireless communication headset
with integrated Bluetooth chip enables
connection to other Bluetooth units
within a radius of approximately 10
metres. No more cumbersome fiddling
with cables and connectors: Once the
connection has been established full-duplex communication is available at any
time - a standard that works around the
world. Operation is conducted via four
buttons: The function button, call button
(PTT/push-to-talk button), volume increase and volume decrease buttons. The
headset is even convincing in very noisy
environments due to its effective level
of sound insulation. It not only ensures
hearing protection, but also enables clear,
reliable communication at very high noise
levels. The efficient noise compensation
of the microphone reduces interference
from ambient noise. Provided the devices
