The 6B-900 series is a single ear muff, over the head, reversible
cable dress headset. Standard configurations include a radio
transmit headset and an intercom only headset, the 6B-900 and
6B-901 respectively. The reversible cable dress eliminates the
need for a Right or Left style. The headsets are always live on the
intercom and have radio Push-To-Talk and volume control located
on the Headset. This series of headset comes with a 15' Coil-Cord
The 5B-EMS900 is a single speaker headset that is
designed to allow the Medical Technician to hear the patient
in one ear and the intercom and radio audio in the other ear.
The headset has a reversible cable dress which allows it to
be worn on either side of the head. Volume control and the
radio PTT button are mounted in the in-line box as shown
left. A clothing clip is provided on the in-line box as well.
Standard configuration provides for a 28-inch straight cord
with a 15 foot coil cord. A 6 foot coil cord is optional. The
single muff encompasses the ear but offers no hearing
protection. The vinyl covered muff, replaceable windscreen
and the waterproof microphone make the 5B-EMS900 easy
to clean up when used for EMS operations.
This is a comfortable durable headset ideal for use in mobile
vehicles where hearing protection is not required.
The “Dash 3” version of the jumpseat headsets uses a
PO/PO (Push-ON/Push-OFF) switch. This allows the
crewmember to talk on the intercom without needing to hold
the PTT button on the headset. This headset is most
commonly used at a Tiller Station or in conjunction with a 25-
0689 15ft Coiled Extension Cable and the Tailboard Station
to assist the driver when backing up.
