Headset Microphone Type Selection Dip Switch
SW1-1 applies only to a dynamic-mic headset connected to the dynamic-mic headset jack on the front panel. If the headset
specifications indicate the microphone type is balanced, or if you are unsure, leave this switch in the off (default) position. If
the specifications indicate an unbalanced microphone set SW1-1 to on.
NOTE: For best results in noisy environments, a noise canceling (directional or carotid) microphone is highly
recommended. This is especially true if you are using the VOX feature.
Mic Kill Send Enable DIP Switch
The US-2002 can generate an inaudible signal that turns off the microphones on all intercom stations on a channel (for stations
that detect this signal). This feature is useful, for example, when an unattended microphone has been left on and is causing
unnecessary noise on a channel. By default, Mic Kill is not enabled.
To activate this feature, do the following:
> Set SW1-6 to the on position.
