OLUME ADJUSTMENT
If you are using a headset, adjust the intercom listen level with the left Volume control on the front panel of the
MS-2002. If you are using a speaker, adjust the intercom listen level with the right Volume control next to the
speaker. External speakers will require their own volume controls
RECEIVING CALLS
1. When there is an incoming call signal on a channel, the Call key for that channel will flash red. There will
also be a beep tone if the beep feature has been activated (page 7).
2. Activate the microphone: If you are using a dynamic-mic headset tap the Headset key to turn the mic on; if
you are using a panel-mounted microphone or an electret-mic headset, tap the Panel Mic key to turn the
mic on.
Note: You can also use the voice-activated microphone (Vox) feature. See page 16.
3. Turn on the Talk and Listen keys for the calling channel and begin your conversation. Turn the keys off
when finished.
Note: When you tap the Headset key, or the Panel Mic key, or any Talk or Listen key, it will lock in the on
position. You may then tap the key again to turn it off. For momentary activation, press and hold the key. It will
remain on as long as you hold it and it will turn off when you release it.

ALLING AN INTERCOM CHANNEL
1. Press and hold the Call key for the channel that you want to call. An inaudible call signal will be sent, and
your listen key for that channel will automatically turn on in preparation to receive a verbal response.
2. When you hear a response, release the Call key.
3. If you are using manual microphone activation instead of Vox, make sure your microphone is on: for a
dynamic mic headset, tap the Headset key to turn it on; for a panel-mounted microphone or electret
headset, tap the Panel Mic key to turn it on.
4. Turn on the Talk key for the channel you called to begin you conversation.
5. Turn off your Talk and Listen keys to end the conversation.
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
MS-2002 as well as all talk channels of any connected EMS4001 Expansion Stations. Use All Talk as follows:
1. If you are using manual microphone activation instead of Vox, 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.
Note: To insure that the All Talk key is never accidentally left in the on position, it does not latch.
