features a mono input and mono PTT output. See your Sonetics dealer for
accessories to match your equipment.
Common Features, Communication Headsets
Auto-Leveling Microphone
The Headset automatically detects the voice of the user against noise in the
background. This gives the headset an automatic VOX (noise gate or squelch) that
needs no adjustment when transitioning from areas of differing noise levels.
Noise Cancelling Microphone
Noise cancelling microphones remove background noise right at the mic element.
This lets listeners hear the person talking and not the background noise.
Radio PTT
The Headset interfaces with any two-way portable radio using the wired AUX input
or wireless DECT connection. When there is a wireless DECT connection, the PTT
signal is passed to the wireless DECT7 Wireless Base Station and onto the Digital
Intercom. Otherwise, the PTT signal is passed to the wired AUX input.
Wireless Bluetooth® Technology
Available on the FHW507, UHW507, & DW501BT headsets.
Bluetooth enabled Wireless Headsets can connect with other wireless Bluetooth
enabled devices. This lets you connect an additional audio or communications
device. Cell phones, mp3 players, mobile radios, computers, etc. expand your
communications potential.
A2DP Audio Streaming
The Headset features integrated A2DP streaming audio functionality, so you can
listen to music or podcasts, and hear turn-by-turn direction information from a GPS
application on your phone. You can also use this feature to stream audio from a
Bluetooth-enabled computer to the headset.
Wireless DECT7 Communications
Available on the FHW507, UHW507, UHW505, & UHW503 headsets
The Sonetics Wireless DECT7 Headsets enable full duplex, conference call like
communications to others on the same channel. The Headsets will connect to
standalone Sonetics Wireless Base Stations or Sonetics IP-DECT7 wireless systems. A
DECT7 network gives up to 1600ft of range (line of sight) from its wireless base,
with interference free, digitally encrypted communications.
Backwards Compatibility
Firecom Wireless Headsets are backwards compatible with Firecom first generation
wireless DECT, and DECT6 Wireless Base Stations with minimal loss in functionality.
Broadcast Mode
The Headset may be paired into a listen only mode of operation, reducing power
consumption considerably. This also allows many more headsets to be connected to
a Wireless Base Station simultaneously. Pressing the Radio PTT button allows the
headset to momentarily talk on any available slot. A tone will let the user know
when they can talk. After talking, there will be a slight delay when other users
cannot be heard. Refer to the Wireless Base Station manual for details.
Dual Dome Antenna Design
Each dome has a separate DECT7 antenna using diversity switching to lock onto the
best signal. The user never needs to worry about head position relative to the
wireless base. The best possible connection is delivered at all times.
Radio PTT or Intercom Only Selection
The Headset may be configured to send a transmit signal to radios connected via a
DECT7 Wireless Base Station or Intercom. The user can transmit over multiple
radios depending on the configuration.
Out of Range Warning
The user is notified when DECT7 signal is weak, or when it goes out of range.
Proximity Pairing
To enhance security, the Wireless Base Station will only pair to wireless DECT7 units
in close proximity. This adds another layer of protection for users.
Signal Strength Reporting
The Headset may be placed into a field diagnostic mode to detect signal strength at
The Headset. This can be used to optimize placement of Comhubs or Base Stations.
Wide Band Audio
Wireless DECT7 communications are transmitted in a high definition wide band
audio format. This gives better sound quality, greater intelligibility, and improves
with voice activated control systems. The Headset can also be used in narrow band
if necessary.
