QUICK START

1. Insert batteries confirming to "+" and "-". Incorrect installation will result in not working or damaging the microphone set.

• Install the 2AA batteries to microphone.
  
• Insert 2 AAA batteries to the receiver. Make sure the battery polarity is correct installation and the door is closed completely.
  

Note:
We do not recommend to use with portable bluetooth speakers lower than 15 watt, such as JBL charge, Doss touch.

3. Turn the microphone and receiver on. When the light on receiver turn from green to RED, they successfully paired. The light stay on RED when it is functioning.
   
4. Slowly adjust the mic volume of the speaker from zero to the desired loudness to avoid feedback noise (howling). The best distance between microphone and speaker should be at least 10'. Now your voice would be heard through the speaker when you talk to the microphone. Extend the antenna of receiver to increase the transmission distance if you need.
   

WARNING OF LOW BATTERY POWER

1. Please change microphone battery when the led screen flashes.
   
2. The battery of receiver need to be changed when the indicator blink green.
   
3. Operation time is limited relative to battery life; To save power, please turn off mic and receiver after use and take the batteries out in time. Not used for a long time will cause battery leaked acid, destroyed microphone equipment.
4. Sometimes a battery gets poor contact with the connector inside microphone/ receiver and results in the same symptoms just like if it was drained.
5. Dying batteries will often register a lower voltage. Some batteries will show nearly full voltage until just before they die. Please replace the new fresh battery in time when low voltage or the mic cut in and out some time.
6. Higher coverage will likely result in quicker battery draining. Please prepare a replacement battery in case microphone set that runs out of charge.

TROUBLESHOOTING

1. The transmitter and receiver need to be in direct line of 'sight' for them to work. Wireless mic easily gets interference and blocked by object like a person walking in front of it antenna, make sure to put its receiver as high as possible and keep away from any large piece metal object.
2. Turn down the volume and treble of the speaker before connecting the receiver to it could avoid feedback noise.
3. Do not point the mic at the speakers, otherwise it will cause feedback noise.
4. When use the mic outdoors, we suggest to keep out from the rain and keep it dry.
5. Not compatible with phones, computers, cameras, tablets, Apple products and all the line in /aux in jacks.
6. If you found the microphone suddenly doesn't work when multiple sets used together, pls change the frequency to have a try.
