T-68 Wireless System User Manual WP-68 wireless system uses UHF frequency band (630-690MHz) to work. There are 100 available working channels for receiving and transmitting audio without delay. Stable working distance is more than 20 meters, using intelligent energy-saving circuit, it can work continuously for more than 7 hours. UHF band has the advantages of good signal transmission stability, wider available radio frequency bandwidth, anti-WIFI and Bluetooth interference. T-68 wireless system, with built-in rechargeable lithium battery and battery management system, can be intuitive observation of battery power. The background noise is very low when working, suitable for stage performances, recording, outdoor bands, personal performances, teaching and other occasions. With user management function, when the system detects that the user has not used it within half an hour, it will automatically shut down the power supply. As to avoid the situation that the battery is short of electricity at the critical moment.

Frequency selection ?In power-off state, press and hold the “ POWER ”button for 1 second to turn on the transmitter. ?At this time, A: Hold on “ CH+ ” button and press “ POWER ” button, the frequency goes up. B: Hold on “ CH-” button and press “ POWER ” button, the frequency goes down. Infrared synchronization ( IR) ? For specific operation, please refer to the operating instructions of the receiver. Power saving mode ?The transmitter will enter the power saving mode after 15 minutes without audio input. Automatic shutdown function ?when the transmitter detects that the user has not used it within half an hour, it will automatically shut down the power supply. Operating instructions for receiver: Power on/off ?Press and hold the “ POWER ”button for 1 second to turn on/off the receiver. Infrared synchronization ( IR) ?In power-on state, press the “ POWER ” button of the transmitter, The LED displays “ C---“ and emits an infrared signal. ?Put IR port of the receiver ( in the power-on state) close to the IR port of the transmitter. ?If “RF/AF” indicator flashes quickly and then lights up, infrared synchronization succeeds. Automatic shutdown function ?when the receiver detects that the user has not used it within half an hour, it will automatically shut down the power supply. Warn: Keep the phantom power of the Mixer off to keep the receiver safe of the reiver.
