1. Important Caution

2. Features

• 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.

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

• PLL synthesized technology is deployed.

• 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 micro-

phones.
