OPERATION
Normal operation of the RM-702 requires access only to the front panel
controls. For intercom operation, set the listen level controls for each channel
to the desired level and press the talk switches when talking. If a headset is
being used, set the sidetone control for the receiving channel for the desired
amount of sidetone in the earphone. If the panel mic and speaker are being
used, set the sidetone control for minimum feed-through to the speaker to
prevent feedback.

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.
