SET-UP & OPERATION
Once the Flexmike is charged, follow these steps for use.
1. Remove the Flexmike from the charger and put it on by connecting the
magnetic clasps behind your neck. Adjust the lanyard so that the top of
the Flexmike aligns with the collarbone.
2. The Flexmike will automatically power on and mute when it is removed
from the charger.
3. The microphone volume on the Flexmike is set at the factory to the
midpoint. It is adjusted by the up/ down buttons on the side of the
microphone when the microphone is not muted.
4. While speaking in a normal voice, fine tune the microphone volume.
Proper volume level should be as follows:
Your voice should be clearly heard by another person on the other
side of the room.
You should barely be able to hear your own voice.
There should not be any audio “feedback” or squealing outside of
2-3 feet (if there is, turn the volume down slightly).
REMEMBER: This equipment supplements the user’s voice so they are able
to speak in a conversational tone. Having the volume set too high will result
in feedback and listener fatigue.
Once initial volume level is set, walk around the room and listen for
overall audio quality.
If further fine tuning is required, you may need to adjust the Tone Control
on the side of the Mobile PA.
If the Flexmike is out of range, it will automatically shut o aer 30
minutes of trying to reconnect. Once you are back in range, simply press
and hold the power button for 1 second on the Flexmike to power it up
and resume normal operation.

Set-Up Location
FOR INDOOR USE
Find a location where the Mobile PA is facing the
audience.
If this is not possible, other good locations are
along either wall next to the speaker or in a corner.
Avoid placing Mobile PA behind or right next to
where the person speaking. Putting Mobile PA in
close proximity to the speakers microphone can
result in feedback.
For quick setup and portability, place Mobile PA on
a tabletop.
Elevate on a tripod to broadcast in a larger space.
CAUTION: When using a tripod, legs must be fully
extended for safety.
FOR OUTDOOR USE
When used outdoors, Mobile PA should be protected
from rain and other water exposure.
Coverage area indoor is up to 1,600 square feet and up to 1,150 square feet outdoor.
15
Companion Speaker
For larger spaces, Mobile PA can operate as a ‘companion’ speaker to expand your coverage
area up to 2,750 square feet indoor and up to 2,000 square feet outdoor. This is simply a
second Mobile PA that has been switched into companion mode.
The Mobile PA in companion mode reproduces what is heard from the primary MPA
speaker. Audio inputs of the companion speaker are heard through both the primary and
companion speakers.
SET UP A COMPANION SPEAKER
1. To set up a second Mobile PA as a companion speaker, slide the mode switch UP to
companion mode on the back of the Mobile PA.
2. Press/hold the Tone button for 5 seconds on companions speaker to place it in pairing
mode. The status light will begin blinking.
3. Then Press/ Tone button for 5 seconds on the primary and companion Mobile PA
speakers to place it in pairing mode as well. The status light will begin blinking.
4. Aer several seconds, the two speakers will connect and the status light on the primary
speaker will turn solid blue and solid white on the companion speaker.
Please note the position of the companion mode switch:
The bottom position of the switch is Mobile PA primary mode.
The top position of the switch is Mobile PA companion mode.
Audio input volume, audio output volume, and tone of the overall system can be adjusted
from either the primary or companion Mobile PA. The volume of the companion speaker
mirrors the volume level on the primary Mobile PA and cannot be adjusted independently.
NOTES ON PAIRING
If a companion speaker was already paired to the primary Mobile PA, it will reconnect
without the need to pair again. However, if the Mobile PA has been paired to another
Mobile PA as a companion speaker or a Media Connector, it will be necessary to pair again.
Only microphones paired to the primary Mobile PA will be in use. Microphones cannot be
paired to the companion unit.
User can pair bluetooth to both primary and companion Mobile PA.
Pairing will be indicated when the status light on both units blink blue/white.
Media Connector (for wireless media) cannot be connected when companion speaker
is in use.
