• Metal Grille: Protects the microphone capsule.
• Uni-directional Dynamic Microphone: Captures sound primarily from the front, reducing background noise.
• Power Indicator: LED light indicating the microphone's power status.
• On/Off Switch: Toggles the microphone power.
• Battery Compartment: Located at the bottom of the microphone (twist to open). Requires 2x AA batteries (not included).

Setup

1. Unpack the System: Carefully remove all components from the packaging.
2. Position the Receiver: Place the UHF-02 receiver on a stable surface, away from other electronic devices that might cause interference. Extend both antennas vertically for optimal signal reception.
3. Connect Power to Receiver: Insert the included power adapter into the DC INPUT jack on the rear of the receiver, then plug the adapter into a standard AC power outlet.
4. Connect Receiver to Audio System: Connect the 1/4" OUTPUT jack on the rear of the receiver to an input on your mixer, amplifier, or PA system using a 1/4" audio cable (not included).
5. Install Batteries in Microphones: Unscrew the bottom cap of each handheld microphone to reveal the battery compartment. Insert two fresh AA batteries into each microphone, ensuring correct polarity (+/-). Replace the cap securely.
6. Power On:
   • Press the POWER button on the receiver. The power indicator LED will illuminate.
   • Slide the ON/OFF switch on each microphone to the "ON" position. The microphone's power indicator LED will light up.
7. Automatic Pairing: The microphones and receiver are designed to pair automatically. Once the microphones are powered on and within range, the RF A and RF B LED indicators on the receiver should illuminate, confirming a strong connection.

Operating Instructions

1. Volume Adjustment: Use the VOLUME A and VOLUME B knobs on the receiver to adjust the output level for each microphone independently. Start with the volume low and gradually increase it to avoid sudden loud sounds.
2. Microphone Usage: Hold the microphone approximately 2-6 inches from your mouth for optimal sound pickup. Avoid covering the grille with your hand, as this can affect sound quality and signal.
3. Operating Range: The system offers a dynamic range of up to 150 feet (45 meters) in open areas. Maintain line of sight between the microphones and the receiver for best performance. Walls, large objects, and other wireless devices can reduce the effective range.
4. Frequency Stability: The system operates within the 533.7+537.2MHz frequency range, designed to minimize interference.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the receiver and microphones. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace microphone batteries when the power indicator LED starts to dim or if audio quality degrades. Always use fresh, high-quality AA batteries. Remove batteries if the microphones will not be used for an extended period to prevent leakage.
• Storage: Store the system in a cool, dry place when not in use. Protect it from extreme temperatures and humidity.
• Antennas: Handle the receiver antennas with care to prevent bending or breaking.
