4. Operating Instructions

4.1 Channel and Frequency Adjustment

The ZERFUN G8 system offers 50 compatible frequencies on each of its 4 channels (4 x 50 total) for interference-free reception. Use the channel adjust and pairing button on each microphone to change frequencies and pair with the receiver if needed.

4.2 Volume Control

Each microphone channel on the receiver has an individual volume control knob (VOL-A, VOL-B, VOL-C, VOL-D). Adjust these to achieve the desired audio levels for each microphone.

4.3 Microphone Usage and Characteristics

The handheld microphones feature sturdy all-metal construction and are cardioid (unidirectional). This means they primarily pick up sound from the front, effectively isolating vocals from background noise. For optimal performance, speak directly into the top of the microphone.

The microphones also feature a channel, battery, and signal display for easy monitoring.

Each microphone bottom comes with a different color silicone cover (orange, blue, black, white) to help you color-code your mics and provide protection.

4.4 Transmission Range and Battery Life

The ZERFUN G8 Wireless Microphone System supports a transmission range of up to 200 feet (approximately 60 meters) in optimal conditions. The UHF frequencies (500 - 599 MHz) are compliant with FCC regulations.

Each microphone provides approximately 7-8 hours of continuous use from fresh AA batteries.
