USING THE AEW-T5000SERIES HANDHELD TRANSMITTER AEW-T5000 transmitter family is as follows: AEW-T5400 AEW-T3300 AEW-T6100 AEW-T4100 The handheld transmitter operates on 2 “AA” batteries. Please make sure that your batteries are fresh. We recommend that you use Alkaline batteries and that you avoid using NiCad if possible. Hold the bottom grip and turn the top grip counter clockwise until bottom grip free to slide. Slide the bottom grip, insert two batteries into the battery compartment and slide the battery compartment back into place. To change the frequency of operation, push and hold the power /mute button located on bottom of the transmitter to turn it on. Unscrew the battery cover and pull the cover back. Push the set button once Using up or down arrow button and scrolls the menu until frequency menu appeared. Push the set button once. Push down or up arrow button and set frequency to the corresponding frequency as set on receiver. Push and hold set button until word “Stored” displayed in a while. Push up or down arrow button and scrolls the menu until “ESCAPE” appeared Push the set button once to return default menu You are now set to use the system. PART4. USING THE AEW-R5200, AEW-R4100 RECEIVERS Plug the IEC plug on the AC cable to the AC inlet on back of the receiver. Plug the 3-pin AC plug on AC cable to an 110V AC outlet. Connect two antennas to the antenna input on back of the receiver. Push the Power switch. Confirm that the backlight on LCD screen comes on. Check the frequency setting to confirm that they correspond to the settings of the transmitter If not, push set button once to display “FREQ” on top line of the LCD. Push set button once and check that “EDIT” displayed on bottom line of LCD brink. Push up or down arrow button to set receiver frequency to corresponding transmitter frequency. Push and hold set button until “STORED” displayed in a while. Push up or down arrow button to display “QUIT” Push Set button once to back in to Default menu. Connect the balanced or unbalanced audio output to your mixer or PA system. Adjust the Volume setting to the desired level. Speak into the microphone and listen to the audio out at the speaker. If satisfied with the audio quality, you ca uses the system.
