Pairing vs Connecting
•
Pairing your mic and receiver creates a sustained link between the two. Your mic and OA
-
50 will each remember its pairing even
after being turned off and on. The act of pairing does not need to be repeated each time you use your mic. Each mic and receiver
channel is paired to at most one other device.
•
Connecting is when data transmits between the two paired devices. When connected, the two devices are communicating with
each other, allowing audio to be passed through and heard. Your mic will automatically connect to your OA
-
50 each time they are
both on.

You may wish to use PTT mode in your classroom to avoid unnecessary rustling noise when students are passing around the
OM
-
20. To use this feature, you must first switch your OM

switch to the left to turn PTT mode on.

main center button is not being pressed, the mic is silenced.
3)
To turn PTT mode off, slide the same switch on the bottom of the OM
-
20 to the right. The mic will then be active continuously
with no need to use the button.
Cleaning your Mic
•
Periodic cleaning of the microphone is recommended to avoid the buildup of common contaminants like dust, lint, dirt, makeup,
and oil. These can clog the windscreen and prevent it from working well.
•
Remove dust & lint build up with a light spray of canned compressed air or a dust cloth.
•
Use a disinfectant wipe to clean leftover build up that did not come off by dusting. Use extra care around the sensitive areas
(charging port, windscreen, and logo button). Take care not to use a wipe with any excess liquid content that could enter the
openings.
•
Dry with a soft, lint
-
free cloth.
Auto Shut
-
off Times
•
