Important Cautions

■Always makes all connections before plugging the unit into an AC power outlet.

■Do not leave the device in a place neither with high temperature nor high humidity.

■Always do not handle the power cord with wet hands!

■Keep the devices away from re and heat sources.

Features

■ Operated in UHF band where there is less RF interference than the VHF band.

■ Due to the PLL synthesized technology, the system oer 16 selectable channel.

■ e diversity reception ensures the stable transmission and reception.

■ Adjustable squelch control can eectively reduce the noise.

■ Tuned antennas can benet the stable RF reception.

■ Built-in Tone key Squelch & Noise Mute detection are available to restrain the interference

signal.

■ Rugged metal housing can pass through the dicult environment.

■ Equipped with balanced XLR and unbalanced for great convenience.

■ Body-pack transmier provides phantom power for condenser lavaliere and headset

microphones.
