Boundary and Gooseneck Base Transmitters
Mute/Active Button
The button is configured to toggle between Mute and Active. The following
options are available:
•
Toggle: Press button to mute microphone, press again to pass audio
•
Push-to-Talk: Hold button to pass audio
•
Push-to-Mute: Hold button to mute microphone
•
Disabled: Button functionality off
High-Pass Filter
Each transmitter contains a high-pass filter.
The high-pass filter:
•
attenuates frequencies below 150 Hz by 12 dB per octave
•
reduces low-frequency noise caused by table vibration or air handling
systems
Transmitter RF Power
Reference the following table for setting RF Power:
RF Power Setting
System Range
1 mW
33 m (100 ft.)
10 mW
100 m (330 ft.)
20 mW
>100 m (330 ft.)
Locking Transmitter Controls
Boundary and gooseneck base transmitters have a power lock to prevent
accidental or unauthorized changes to the transmitter. When the power lock
is on, the transmitter's power switch is disabled.
To unlock, use receiver front panel or Wireless Workbench.
Menu path: IR PRESETS>GOOSENECK / BOUNDARY>POWER LOCK
Setting Initial State From Charger
Use the receiver front panel or Wireless Workbench to control a transmitter's
state after you remove it from a networked charging station.
•
Active: On and passing audio
•
Muted: On but the audio is muted
•
Off: Power is off
Audio Signal Encryption
When encryption is enabled, the receiver generates a unique encryption key
which is shared with the transmitter during an IR sync. Transmitters and re-
ceivers that share an encryption key form a protected audio path, preventing
unauthorized access from other receivers.

Application
For increased channel reuse
at close distances
Typical setups
For hostile RF environments
or long-distance applications
Change button behavior using Wireless Workbench or the receiver front
panel.
Menu path: IR PRESETS>GOOSENECK / BOUNDARY>MUTE BUTTON
BEHAVIOR
Note: When the mute/active button is set to Disabled, the transmitter will still
send TPCI data if the button is pressed.
Adjust high-pass filter settings using Wireless Workbench or the receiver
front panel.
Menu path: IR PRESETS>GOOSENECK / BOUNDARY>HIGH PASS
Menu path: IR PRESETS>GOOSENECK / BOUNDARY>RF POWER
Note: Using the 20 mW setting decreases the transmitter battery runtime
and reduces the number of compatible systems.
Attempting to access a locked feature will display the following message on
the receiver front panel:
Menu path: IR PRESETS>GOOSENECK / BOUNDARY>INITIAL STATE
FROM CHARGER
Note: If Mute Button Behavior is set to Push-to-Talk and Initial State From
Charger is set to Active, the transmitter will only pass audio when you push
the mute button. Make sure to coordinate settings for Mute Button Behavior
and Initial State From Charger.
Enable encryption using Wireless Workbench or the receiver front panel. For
more details, see the user guide for your receiver.
