Quick Start User Guide
CXR16 SERIES
Thank you for purchasing the Entel CXR16
throat microphone. This user guide will
explain the features of your microphone,
which with care should provide many years of
trouble-free operation.
The CXR16 is a high-performance throat
microphone that delivers clear, intelligible
audio transmissions, even in high ambient
noise environments.
FITTING
Choose on which side you prefer to wear
the earpiece. The throat microphone should
be worn on the same side, adjacent to your
Adam's apple. Ensure that the microphone is
applied directly to the skin with no clothing in
between. Fasten the Velcro band securely and
comfortably around the neck, while maintaining
the position of the throat microphone. Connect
the audio connector to the PTT unit.
OPERATING INSTRUCTIONS
•
Insert the Nexus connector of the CXR16
directly into the PTT unit.
•
Attach the PTT unit to a pocket or collar
using the clip on the rear of the PTT unit.
•
Press the PTT button to transmit and
release to receive.

IMPORTANT
Always switch the radio off before
attaching an audio accessory. Models that
are certified to ATEX & IECEx have been

use, any labels be removed or become
illegible please return the accessory to
Entel for relabelling.
Please note that the use of a connector
other than the Nexus connector may
damage the socket and invalidate the
warranty.
