use our products, please read this Owners Manual, so that you can enjoy it. Keepthis

manuaI in a safety place for your future references.

This series professional wireIess microphone system introduces a number of

advanced technology and components, incIuding the efficient low-consumption RF

transmission technology,elimination of switching impact technology, slow changed

output controI technology,superb sensitive VHF narrowband receiverand etc..

EDA, online simulation accessoriaI design and strict quality controIare applied to

ensure each system with excellent electronic function.

Desktop receiver and enhanced muting, high signal / noise ratio.

Almost zero noise output when standby.

Broad frequency response range, super low distortion.

No impact on switching receiver, ensure safety of rear stageamplifier system and

speaker.

Perfect operative status signals, fluorescence display, with digital microphone.

Long practical distance. Over 30 m in ideaI circumstances; practical 20 m radius in

complex circumstances.

Dual frequency design. Be able to use two microphones at the same time without

mutuaI interference.

Applicable for medium& small stages, karaoke halls, and home entertainment etc.

Features:

1. Be sure to check whether thelocal voltage accord with operativevoltage of the

microphone before using, make correct selection.(Wrong selection may leadto

burnout of the whole machine.)

2. Please don t open or dismantle the machine on your own. For internaI repair, please

contact the locaI distributor or accepted service center.
