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. PART 3. USING THE ATW-T341 HANDHELD TRANSMITTER 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 the batteries into the battery compartment and slide the battery compartment back into place. To change the frequency of operation, push and hold power /mute button located on bottom of 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 ATW-R310 RECEIVER Connect the AC adapter DC output connector to The ATW-R310 DC input jack Plug the 2 blades AC plug on AC adaptor AC cable to an 110V AC outlet. Push the on off 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 and hold set button until frequency only displayed on LCD Push set button once and check that frequency displayed on LCD brink. Push up or down arrow button to set receiver frequency to corresponding transmitter frequency. Pus set button once to set frequency. Push up or down arrow buttons to scrolls menu until VR and percent figures appeared If it not set to the VR 100%, push set button once and check that item displayed on LCD brink Push up arrow button to set it to maximum. Push set button once to set Push and hold Set button until LCD displayed “DEF” in a while 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 use the system.

From 100 to 250% of the authorized bandwidth they are attenuated by at least 35dB and beyond 250% 43 log(Po) dB. The plot shows the transmitter modulated with 15000 Hz(the highest modulation frequency), adjusted for 50% modulation plus 16 dB. The spectrum analyzer was set with the un-modulated carrier at the top of the screen. The test procedure diagram and occupied bandwidth plots follow.
