Two modes are available:
• Push to Talk: In this mode the audio
signal on the talkback output channels
is normally muted. The audio signal will
become active whenever its associated
pushbutton is pressed and held.
• Hybrid: This mode is a combination
of push to talk and latching action. If a
pushbutton is pressed and held the au-
dio signal associated with that talkback
output channel will become active until
the pushbutton is released. If a push-
button is momentarily “tapped” the
audio signal on the associated talk-
back output channel will change state.
Upon power up the audio signals on the
talkback output channels will be in their
muted state.
Button Backlight Intensity
Switch 4 selects the intensity of the white
LEDs that provide backlighting for the four
pushbutton switches. Two choices are
available: low and high. Low is appropriate
when the Model 216 is to be used in an
environment where the ambient light level
is low. High would be appropriate where
other light sources in the physical area
may make the pushbuttons more difficult
to identify. High may also be useful when
identification markings have been inserted
under the clear lens caps.
• Push to Talk: In this mode the audio
signal on the main output channel is
normally muted. The main audio signal
will become active whenever the push-
button is pressed and held.
• Latching: In this mode the audio signal
on the main output channel will change
between its active and muted states
whenever the pushbutton is pressed.
Upon power up the audio signal on the
main output will be in its muted state.
• Hybrid: This mode is a combination
of push to talk and latching action. It’s
similar to the way talk pushbuttons
function on user stations associated
with broadcast and production intercom
systems. If the pushbutton is pressed
and held, the audio signal on the main
output channel will become active until
the pushbutton is released. If the push-
button is momentarily “tapped” the
audio signal on the main output channel
will change state. Upon power up the
audio signal on the main output channel
will be in its muted state.
Talkback Button Mode
Switch 3 configures the way the talkback
pushbuttons function.
