Turn the knob to MAX direction for increasing the volume, turn the knob to MIN direction for decreasing the volume until power off Indicator: shows the working status No light: means power off...
Transmitter Operation 1. Wear the headworn mic or lavalier mic, plug the microphone into the MIC socket of transmitter 2. Turn on the transmitter, adjust the volume to minimum, point the infrared frequency pairing window the receiver infrared frequency pairing window (the receiver should be turned on, the frequency is automatically matched when the receiver and transmitter are pointed to each other correctly).
WDA-700 not use the device to charge other battery, improper use may cause a risk of explosion. Do not charge a non-rechargeable battery 10. Put the device and its accessories in a dry and ventilated place, keep them from rain, water, avoid falling down heavily and don't cover the ventilation hole 11.
