Instruction manual

RM-702 TWO-CHANNEL REMOTE STATION
1-4
CALL BUTTONS
Each channel has its own call button. Pressing the call button at any time will
send a call signal on that channel regardless of the activation of the talk circuit for
that channel.
The call button for that channel will flash red while the call button is pressed
indicating the presence of a call signal on the line.
VOLUME CONTROLS
Each channel has a separate volume control for monitoring incoming audio.
Listening is always on and is not controlled by any logic. To listen to a channel,
turn up the appropriate control. To not listen to a channel, turn the control
completely off.
SIDETONE CONTROLS
Each channel has a sidetone null control. This control sets the amount of the
microphone that is heard in the earphone from that channel.
This control is a true hybrid null control and therefore is sensitive to changes in
line loading. For headphone use, it is best to find the null for a given channel and
then rotate the control clockwise to obtain the desired sidetone level.
If the speaker and panel microphone are used together, providing a possible
acoustic feedback path, it will be necessary to use an almost complete null of the
sidetone control.
PROGRAM SEND LEVEL CONTROL FOR CHANNEL A AND B
Both channels A and B have a program send level control that sets the volume of
program audio being sent to that channel when the program is activated.
SPEAKER ON/OFF SWITCH
The switch marked speaker on/off is used to turn the speaker on and off.
MIC SELECT SWITCH
The mic select switch enables the operator to select which microphone is active.
PROGRAM MONITOR LEVEL CONTROL
The program volume control sets the amount of the program signal heard directly
in the headphone or speaker. This control only affects what is heard in the
headphone or speaker and does not affect program feed to the intercom lines.
