Microphone Mute During Talk
You can mute the microphone while talking. Simply tap either the Headset key or the Panel Mic key, whichever is currently being used. Tap the key again to turn the microphone back on. (If you are using Vox, tap the key twice to reactivate vox.)
All Talk
You can talk to all intercom stations that currently have their listens activated. This applies to both channels of the US2002 as well as all talk channels of any connected ES4000A Expansion Stations. Use All Talk as follows:
1.If you are using manual microphone activation, make sure the proper microphone switch is turned on (either Headset or Panel Mic).
2.Press and hold the All Talk key while talking. Release it when finished.
☞To insure that the All Talk key is never accidentally left in the on position, it does not latch.
Public Address (PA)
If the PA output on the back panel of the US2002 is connected to a public address system, you can talk on the public address system as follows:
1.If you are using manual microphone activation, make sure the proper microphone switch is turned on (either Headset or Panel Mic).
2.Press and hold the PA key while talking. Release it when finished.
To insure that the PA key is never accidentally left in the on position, it does not have latching operation.
Turning the Program Inputs On and Off
1.Insure that program inputs have been connected at the back panel and that the program sources are on.
2.Press and hold the Mic Kill key for about 2 seconds, then release it. It should now be glowing green to indicate that the US2002 is in programming mode.
3.The current status of the program inputs is indicated by the Talk keys. If the channel 1 Talk key is lit, the program 1 input is currently activated to channel 1; if channel 2 talk is lit, program 2 is activated to channel 2. Tap either Talk key to turn the program input for that channel on or off.
4.When the program inputs are configured as desired, tap the Mic Kill key to exit program ming mode and return to normal operation.
5.Adjust program 1 and 2 levels via the trimmers on the back panel of the US2002.
