Internal Speaker And Microphone Operation; Optional Desk Microphone Or Headset/Footswitch Operation - Motorola MC3000 Operating And Installation Manual

Internal Speaker and Microphone Operation

You use the internal microphone to transmit calls and the internal speaker to receive calls
in a low noise environment, without using the handset. You cannot transmit and receive at
the same time.
To transmit:
1. Ensure the handset is on-hook (in the cradle).
2. Press and hold the Transmit button. The Transmit LED turns on while the button is
pushed.
3. Speak in the direction of the internal microphone (located slightly to the right of center
on the bottom edge of the console).
4. Release the Transmit button to listen for a response on the internal speaker. The
Transmit LED turns off when the button is released.
Always allow a short delay after pressing the Transmit button, and before speaking, to
allow time for the radio channel to be established. For the best transmit audio quality,
maintain a speaking distance of 18 inches from the internal microphone.
To receive:
1. Listen for receive audio from the internal speaker.
You can only hear the receive audio if the Transmit button has been released.
Note: When configuring the deskset, the installation technician has the option of disabling
the handset and/or the internal microphone.

Optional Desk Microphone or Headset/Footswitch Operation

Optionally, you can connect and use an external deskmic or headset/footswitch to transmit
calls and the internal speaker to receive calls in a low noise environment, without using
the handset. With the deskmic, you cannot transmit and receive at the same time. With the
headset/footswitch you can transmit and receive at the same time. You must use the Digi-
tal Radio Function button to monitor the radio channel, not the monitor button on the desk
microphone or footswitch.
To transmit:
1. Ensure the handset is on-hook (in the cradle).
2. Press and hold the Transmit button on the deskmic or footswitch. The internal micro-
phone is disconnected and the Transmit LED turns on while the button is pushed.
3. Speak in the direction of the desk microphone or headset microphone.
4. Release the Transmit button to listen for a response on the internal speaker. The
Transmit LED turns off when the button is released.
Always allow a short delay after pressing the Transmit button, and before speaking, to
allow time for the radio channel to be established. For the best transmit audio quality,
maintain a speaking distance of 18 inches from the desk microphone.
