1. System operation instructions
2. Features
• Before connecting to power, make sure the voltage marked on equipment is the same as that
on the power socket.
• Do not place the equipment in damp and hot environment.
• Prior to operation, please dry your hands.
• Keep the equipment away from re and heat source.
• Transmier and receiver need to be adjusted to the same “default channel” or “frequency”.
• UHF true diversity technology renders 200-480 meters of operation distance
• Maximum 2400 to 3000 selectable frequencies across 60 to 75 MHz
• Preset 15 groups each of up to 63 compatible channels
• User programmable 6 groups each of 64 channels
• Free space scan function
• JTS Patented obstacle-free RF function synchronizes a transmier by pushing
a buon
• JTS LCX circuit design technology minimizes Companding noise
NEWEST FEATURE:
• e now sends not only the frequency data but also transmier’s RF power,
sensitivity, low cut, key lock and user’s name.
• RF “NO SIGNAL” alert function.
• AF “MUTE” alert function.
• Transmier “LOW BAERY” alert function.
• Built in equalizer
• Power / Antenna cascading output provided. (UF-20R Only)
