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.

The rest of this section is a detailed description of each control.
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.
