{section}
{column: 69 %}
Revolabs xTag is a wireless microphone with noise cancelling capabilities. It's base works as receptor and as charging bay.
A complete manual is available [here|http://revolabs.com/Documents/xTag-USB/xtag_manual_v1-5.pdf]. The instructions above are based on this manual.

h5. Pairing

The LED will be solid RED until pairing is complete, as indicated by double flashing RED on both the Microphone and the Base (paired and muted audio). If pairing fails at the end of one minute on either unit, the LED will flash alternately GREEN and RED for a few seconds and turn OFF. If this happens, repeat these steps.


h5. Mute
The button on the front of the Microphone mutes it as well as the one on the Base. Press it just for a moment to mute/unmute the Microphone.

h5. Attachment

The Microphone should be attached on the clothing about 15 to 30 cm from the mouth, with the top of the microphone facing up. It must never be use on the hand or on the furniture, since vibrations will mess up whit the noise cancelling mechanism.

h5. Battery

A fully charged Revolabs xTag last 8 hours working. The battery charges from fully depleted to fully charged in approximately two hours, however, it is “quick-charged” to 80% capacity in 45 minutes. Then, it's recommended to place the microphone back to the base during long breaks.

To charge the batteries place the microphone into the bay properly. During charging, the Microphone status LED indicator changes from solid RED to solid GREEN as charging completes. The Charger Base status indicator remains off during charging.The Microphone is always muted while in the Charger Base.

Before using the Microphone for the first time, charge for 8 hours or overnight in the base (until microphone LED turns solid GREEN).

When the Microphone LED begins flashing alternating YELLOW and RED or YELLOW and GREEN, the battery needs recharging.

h5. Range
Revolabs xTag works in a range of 20m. If the microphone is moved out of range of the Base Station (~65 feet or 20m) 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 remind the user to return the microphone to the room. If the microphone is moved back into range within 15 minutes the connection will automatically be re-
established to its original state, and the beeping will cease. If not, the microphone will turn off.
