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 eectively reduce the noise.
• Tuned antennas can benet 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 dicult environment.
• Equipped with balanced XLR and unbalanced for great convenience.
• Body-pack transmier provides phantom power for condenser lavaliere and headset micro-
phones.
