It is our hope that the system will bring you years of trouble free pleasure and performance. Please follow the information contained in this manual closely as it will assist you in using your equipment effectively. PART1. REGULATORY REQUIREMENTS. FCC PART 15 COMPLIANCE STATEMENT CANADA RSS-210 COMPLIANCE STATEMENT “This device complies with Part 15 of the FCC rules. Operation is subject to the condition that this device does not cause harmful interference” “This device complies with INDUSTRY CANADA R.S.S. 210, en confomite avec IC: RSS-210/CNR210. Operation is subject to the following conditions: (1) This device may not cause harmful interference and (2) This device must accept any interference received, including interference which may cause undesired operation.” Please note that your ATW-30000 system operates in a frequency band in a way which may make its use subject to certain FCC and other regulatory agency restrictions and licensing requirements. For further information, Please contact your local office of the FCC as applicable. NOTE: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER'S AUTHORITY TO OPERATE THE EQUIPMENT. PART 2. USING THE ATW-T310 BELTPACK TRANSMITTER The beltpack 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. Open the battery door by slide door lock towards arrow direction and lift door. Insert the batteries into the battery compartment and close the battery door Slides the LCD set up buttons cover down to bottom Push and hold the power switch and turn the ATW-T310 on Push the set button once Using up or down arrow buttons and scrolls the menu until frequency menu appeared. If current frequency setup appeared on the LCD is not the same as corresponding receiver frequency, push 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 input menu (MIC or INSTRUMENT) appeared. If current input setup appeared on LCD screen is not correct, push set button once Using up or down arrow button to select input. Push and hold set button until word “Stored” displayed in a while. Connect your microphone or guitar cable to the connector on the top side of the transmitter. \ Confirm that the receiver is receiving RF and the audio is passing through the receiver. 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.
