15.  TROUBLESHOOTING 

 

Problem 

Possible Causes 

Solution 

Power/Battery lamps does not light 

(for both red and green indicators) 

even when the microphone is 

turned on. 

Is the battery polarity correct? 
Is the battery capacity low? 

Replace the battery correctly. 

Replace with new battery. 

Interference from other wireless 

microphones used at the same 

time. 

Is other wireless microphones set the 

same bank number and different 

channel number? 

Is the distance between wireless 

microphones too close? 

Is the wireless microphone too close 

to the antenna? 

Refer to frequency table and reset 

Bank/Channel. 

 

Keep a distance of at least 50cm 

between microphones when using. 

Keep a distance of at least 3m between 

wireless microphone and antenna when 

using. (*Depending on the antenna 

location and the coaxial cable length.) 

Sometimes the chime is not 

activated. 

Are the A/B switch and the chime 

switch set correctly? 
Have you turned on the microphone 
immediately (within one second) after 
turning it off? 

Ensure correct setting. 

 

This is normal. 
Do not turn on the microphone within 
one second of turning it off. Incorrect 
operation may cause the chime to 
repeat continuously.
