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 SW1-4 selects the intensity of
the white LEDs that provide backlighting
for the three pushbutton switches. Two
choices are available: low and high. Low
is appropriate when the Model 215 is to be
used in an environment where the ambient
light level is low. High would be appropri-
ate where other light sources in the physi-
cal 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.
