TALK BUTTONS
Each channel has its own illuminated talk button for activating the microphone
feed to a given channel. Mechanically, the pushbutton is momentary in action;
however, electrically the button has dual action (momentary or latching)
depending on how the button is pressed. The latching function can be defeated
with a rear-panel DIP switch.
• LATCHING: Pressing the button quickly will toggle the talk function,
alternately turning it on or off.
• MOMENTARY: Pressing the button for longer than 1/4 second will turn
the button press into a momentary function such that when the button is
released the talk function will turn off. In any case the talk function is
activated all of the time the button is pressed.
• TALK INDICATION: The talk button illuminates yellow when a talk is
activated and blue when talk is not active.
• CALL INDICATION: The call button will flash red when a call signal is
received on that channel.
• AUTO-CALL ON TALK: Each channel can be set to send a call signal when
the talk function is active. This function is used to activate IFB circuits or
any other call-activated function available on other stations. A DIP switch
on the rear panel activates this function.
• SPEAKER DIP FUNCTION: Pressing either talk button will reduce the
output level of the speaker by a set amount to avoid feedback.
