SET UP MANUAL MODE 4.2 Set up interference-free channel on receiver Notice: Do not put two or more transmitters operate nearby when set up the frequency channel. Please keep transmitter at least 1 M away from receiver. 4.2.1 Manual Mode Set up interference -free channel by manual operation. ¾ Press the button to turn the power on. ¾ Press button “SET” for 1 second to let channel flashing on the LED display. ¾ Press △▽ change the channel forward or backward.
SET UP AUTO-SCAN MODE 4.2.2 Auto-Scan Mode Set up interference-free channel by auto-scan programmed search. Press the button to turn the power on. Press button “Set” for 3 seconds to search the next interference-free channel automatically. The auto-scan system would stop at the next interference-free channel. Stop pressing button and let LED display flashing five times to lock the setting. NOTE: If user need to set up a multi-receiver system, please keep your previous receiver-microphone pair power on.
