QUICK SETUP

A. Remove packing material
B. Set up the AWR6304U receiver

1. Open the battery cove of the body-pack receiver by pushing the battery cover in the direction away from the LCD display.
2. Place two 1.5V M batteries into the battery housing with the battery polarity orientations as indicated.
3. Slide the cover in the direction toward the LCD display to close the battery cover. Plug the supplied earphones into the earphone output jack on the body-pack receiver.
4. Turn on the power of the body-pack receiver. The LCD will display the current state of the receiver.
5. Check the RF signal reception indicator ( ****) (refer to numeral 5 on page 4). If there is no RF signal . proceed to next section (Section C). If the RF signal is present change the wireless frequency of this AWR6304U receiver. Repeat this step until no RF signal showing on this receiver.

C. Install the AWX6304U transmitter

1. Place the AWX6304U transmitter at least 3.5 feet (1 meter) away from the ground and all walls. Also, keep the AWX6304U transmitter as far away as possible from any electromagnetic noise sources.
2. Mount the antenna onto the antenna jack. The antenna needs to be set at a 45-degree angle. Make sure that the antenna is NOT enclosed in a large metal body.
3. Plug the supplied AC/DC adaptor 13-15VDC output connector to the AWX6304U transmitter’s DC input, and then plug the AC input of the adaptor to a 120V AC outlet (North America).
4. There are two ways to connect the inputs of the AWX6304U transmitter to the audio outputs of a mixer or a sound system: (1) Use the supplied unbalanced audio cables (two cables each with”1/4″ TS connectors on both ends) to connect the unbalanced inputs (both 1/4″ jack) to the audio outputs on a mixer or a sound system; or (2) use two balanced audio cables (cables with a male XLR connector at one end and a female XLR connector on the other end OR cables with 1/4″ TRS connectors on both ends; balanced cables not included in the package) to connect from both the balanced inputs to two balanced audio outputs on a mixer or a sound system.
5. Turn the audio level adjustment knob all the way to the minimal audio position. Turn on the AWX6304U transmitter by pressing the power On/Off button. After the transmitter is turned on, the LCD on the front panel will display the current state of the system. (Note: The audio level adjustment knob will be adjusted to its optimal position after the receiver is turned on as discussed in the following section.)
6. If the frequency of the AWR6404U receiver was changed in step 5 of the previous section (Section 13), change the frequency of this AWX6304U transmitter to match the receiver frequency.

D. Setting up the AWM6304U system

1. Adjust the audio level control knob on the mixer or the sound system, which is connected to the AWX6304U audio inputs, to the 12-o’clock position and then adjust the audio level adjustment knob on the AWX6304U to have an optimal sound level. If the sound seems abnormal, it may be caused by overdriven inputs of the AWX6304U. Adjust the audio level adjustment knob on the mixer or sound system to a lower level and turn the audio level control knob on the AWX6304U to a higher level until the abnormal sound quality is eliminated. The AWX6304U is now ready.
2. The frequencies of all new AWM6304U systems are as preset or adjusted in step 5 of Section B and step 6 of Section C. If more than one AWM6304U system is to be used at the same time at the same location, the frequencies of the additional AWM6304U systems need to be adjusted to be different to avoid any frequency interference.

Caution
This system is able to produce a high acoustic pressure level. The nominal sound pressure from the earphones can exceed 85dB To prevent ears from damages, the time of exposure to high sound pressure levels should be shortened. The following table illustrates the relationship between the maximum allowed sound exposure time duration and the sound level (in dB)

OPERATION NOTES

1. The AWR6304U needs to be turned off before changing the AA batteries.
2. Signal dropout or unexpected noise may be caused by a low battery or by an excessive distance between the transmitter and the receiver. If you encounter signal dropout or unexpected noise, please check the batteries first. If the batteries are still fresh, try to readjust the antennas on the AWX6304U transmitter.
3. Avoid placing the transmitter in a comer to prevent any RF reception deterioration.
4. Avoid placing the transmitter antennas close to an obstruction or close to any metal surface.
5. Try to place the transmitter as far away from the digital equipment, including computers and CD players, as possible.
6. If more than one AWX6304U wireless transmitters are stacked together or placed in a rack, do not let the antennas touch each other or cross each other.
7. Before the AWM6304U is to be used in a new location, place the AWX6304U transmitter at the intended location and walk through the area with the receivers to locate any radio frequency blind spots, where a momentary loss of sound or short period of noise may occur whenever the receivers are moved to these spots.
8. Do not drop the receiver on the floor or strike the receiver with any object.
