2.4.4
Intercom-Level Control
This control sets the listen level required on the speaker or headset. It does not
affect the program-input level.
2.4.5
Sidetone Control
This knob adjusts the level of the operator’s voice that is heard while talking on
the intercom. Setting a comfortable level of sidetone will ensure that the intercom
line sounds alive,
and also helps modulate the operator’s voice relative to other
voices on the line.
Typically, different sidetone settings are needed depending upon whether the
speaker is used. Turn the knob clockwise to increase the sidetone and counter
clockwise to decrease it. Minimum sidetone is recommended when the speaker is
used.
Note:
Do not connect Pins 1 and 3 together. Headset extension cords or headset “Y”
cables are not recommended because they may increase crosstalk between
channels.
2.4.6
Program-Level Control
This control sets the program input audio level heard in the headset or panel
speaker.
2.4.7
Speaker ON/OFF Switch
This switch turns the front-panel speaker on or off. It also controls whether the
tone alert is heard through the speaker. The speaker volume will automatically dip
when the talk function is set, unless the VOX function is enabled.
2.4.8
Mic-Select Switch
This switch selects whether the panel microphone or the headset microphone is
active. When the VOX feature is enabled, it is only operational when the panel
microphone is active.
