Product Diagram
The diagram illustrates the FM Wireless Headset Microphone system. It shows a headset with a flexible boom arm ending in a microphone. A control unit is mounted on the headset band, featuring:
- A "Power on key".
- A "Switch button" for adjusting volume and frequency.
- "Up" and "Down" keys for frequency and volume adjustment.
- A "Digital display screen" showing "5'LOI" and frequency information (e.g., 107.5M).
- A "5V charge plughole".
- Indicator lights: A blue LED signifies operation, while a red LED indicates charging.
The diagram also indicates that the headset must be "worked at same frequency" as the FM radio or Sound amplifier for proper function.
Using Method
Article 1 of the Method
- Upon powering on the FM wireless microphone, the display shows a red digital number band range, which can be switched to any band, for example, 107.5MHZ.
- Power on the device with FM radio functionality, extend the antenna, and switch to FM mode.
- Initiate an automatic source search on the player. Once the source is fixed, press the up/down keys to finalize work at the same band frequency.
- Wear the FM wireless microphone and match it to the same frequency as the player for successful automatic linking.
- The volume of this FM wireless microphone can be adjusted; refer to Article 2 of the user notice for operating methods.
Article 2 of the Method
- Power on the device with FM radio functionality, extend the antenna, and switch to FM mode.
- The player's screen displays the radio digital band range; select any band, for instance, 87.5MHZ.
- Power on the FM wireless microphone and match its frequency to 87.5MHz using the +/- buttons. Ensure the frequency band remains at the same position.
- Automatic linking occurs when operating on the same frequency band. Wear the microphone to begin amplifying sound.
Attention
To avoid noise, tune to a frequency band that can be heard clearly. For reduced noise, operation is typically effective up to 100MHZ.
Common Problems and Treatment Methods
Problem 1: Shouting when microphone and receiver are very close?
Reply: This is related to product usage distance, volume size, and sensitivity. Advise keeping the microphone and receiver at least 2 meters apart or adjusting the volume size for proper operation.
Problem 2: Why doesn't the microphone connect with the receiver?
Reply: Inspect the microphone and receiver to ensure they are turned on, operating on the same frequency band, and have a full battery.
Problem 3: Does the player work with noise or radio interference during operation?
Reply: Check the operating frequency band for conflicts with local radio frequencies. It is recommended to use a frequency band not already in use locally. The company suggests using the frequency of 106.4MHZ, though some noise may still exist due to background receiver noise.
Problem 4: Why does it work better outdoors than indoors?
Reply: The antenna must be pulled out regardless of whether you are indoors or outdoors. Better quality outdoors is due to fewer obstructions and less radiation interference.
Problem 5: Why is there no sound after successful matching?
Reply: Check if the microphone and receiver are powered on.
Problem 6: Does the voice make distortion?
Reply: Check if the microphone and receiver are operating on the same frequency band. If not, voice distortion may occur.
