TROUBLESHOOTING

PROBLEM| RECEIVER OR MICROPHONE TRANSMITTER STATUS| POSSIBLE SOLUTIONS
---|---|---
Microphone cut in & out;
Microphone working range very short;
Microphone sound lot of noise, too much
feedback or sound weak;
Receiver RF Signal Indicator flashes| First check the normal working status of microphone and receiver:
1. Receiver power Indicator is on;
2. microphone power Indicator is on;
3. Receiver RF Signal Indicator A, Bis on (Means microphone A, B have connect with receiver rightly). If all yes, it means
microphone and receiver device have no problem| Very likely that the current microphone frequency is being
disturbed, so we need to switch microphone frequency to avoid interference(How to change microphone frequency, refer to User Manual -> Page 6 -> OPERATING
INSTRUCTIONS -> POINT 1). See whether this can solve the problem If not, try to reset current microphone connection with receiver(How to reset, refer to User Manual -> Page 6 -> OPERATING INSTRUCTIONS -> POINT 3), then change microphone frequency again. The above operations can basically solve most product problems. Besides, you also need to notice potential nearby sources of RF interference, such as CD players, computers,digital devices, earphone monitoring systems, etc
Microphone not working; can’t come on| If microphone power Indicator flashes| Microphone run out of batteries, need to recharge.
