2. Directional Tabletop microphones should be located on the table with the acoustic cover pointed
toward the users, trying to keep the microphone 2 to 6 feet (0.6 to 2m) from the target person or
two. The pick-up pattern for this directional microphone is ~+/- 45º to either side of directly in front
of the microphone. It is always better to be as close to the person speaking as possible, but avoid
placing the microphone where it might be blocked by equipment or paperwork. Avoid placing
microphones too close to an audio or video conference speaker to avoid echoes. Make sure that
the microphone is always placed lying on its rubber feet atop a flat surface. Refer to diagram
below:
3. With the microphone in position, un-mute the microphone by pressing and releasing the Mute
button (confirm by a flashing GREEN LED).
4. To turn microphone off, return the microphone unit to the Charger Base or press and hold the
Mute button for ~10 seconds until the LED turns solid RED and release button.
If the microphones are placed too far from the Base Station (~150 feet or 50 meters) the connection
will be dropped (LED flashes all colors) and the microphone will mute. After 15 seconds the
microphone will beep 5 times, and will continue beeping every 30 seconds to indicating it’s out of
range.
Move the microphone closer to the Base Station and the connection will automatically be re-
established to its original state, and the beeping will cease. If not, the microphone will continue
beeping until it turns off in about 15 minutes.
