Description of Features
Microphone and Speaker (Figure 1)
The microphone in your MXD3G unit is sensitive enough to hear voice communication around corners
and in other rooms of your home. You do not need to be in the same room with the MXD3G unit for the
response center to hear you! Your MXD3G unit’s audio system is engineered to provide for an increase
of up to 83 times the normal volume.
Control Buttons (Figure 2)
The Reset and Test Learn (T/L) buttons are placed on the back of the MXD3G. These two buttons and the
base unit HELP button on the top of the unit are used to conduct range tests, turn off the MXD, program
the MXD3G to recognize personal help buttons (PHBs), and for other uses. See pages 10 - 16.
Two-Way Voice Communications
After connecting to the response center, your MXD3G unit shifts to a voice communication mode. The
MXD3G usually operates in duplex mode, where both the attendant and you can talk at the same time.
Some response centers can also place the MXD3G in simplex mode, and switch the unit between “talk”
and “listen” modes. Simplex mode can greatly improve the clarity and range of communications
between you and the attendant during certain situations.
