How to use

Install batteries according to the transmitter’s battery compartment instructions and switch the unit on. Set the paired UHF receiver to the corresponding frequency or channel that matches 523.1 MHz. Perform a soundcheck and adjust the receiver input gain to obtain a clear signal without clipping. Hold the microphone 5–15 cm from the mouth for speech or slightly further for loud singing, and avoid covering the grille. After use, switch the transmitter off and remove batteries if the device will be stored for a long time.
