If any problem persist, please consult our local dealer, or contact us directly. Symptom Meanings Remedy The units does not turn on The batteries become drained quickly. The channel cannot be changed There is no sound. The polarity orientation of the batteries in the battery compartment is incorrect. The batteries are exhausted. The battery terminals in the transmitter are dirty The batteries are exhausted. Manganese batteries are being used. The BY-WM8 Pro components is being used under cold conditions. An attempt was made to change the channel by pressing the SET button only. The channel setting on the transmitter is different from that on the receiver. Insert the batteries with the correct polarity orientation. Replace the batteries with new ones. Clean the + and - terminals with cotton swab. Replace the batteries with new ones. Use alkaline batteries. The battery life of a manganese battery is less than half that of an alkaline battery. The batteries drain quickly under cold conditions. Restart the unit, then change the channel with the + and -
buttons. Use the same channel setting on both the transmitter and receiver. The sound is weak. The attenuation level on the transmitter is too high. The line input is selected on the transmitter. There is distortion in the sound The attenuation level on the transmitter is too low. The input level of the transmitter is low. Press the button on the transmitter in attenuation level setting mode to decrease the attenuation level. Pull the cable out from LINE IN. The input level of the receiver is extremely high. Press the + button on the transmitter in attenuation level setting mode to increase the attenuation level. There is distortion in the sound The transmitter and the receiver are set to different channels. Headphones with a mon-
aural min jack is used. Set the transmitter to the same channel. Use the headphones with a stereo mini jack. The audio is noisy or distorted. This can include drop outs, white noise, bursts, pops and clicks. RF interference
.Try a different channel. Make sure both units are on the same channel. Try to position the antennas at a 45 angle in relation to each other. There can be a lot of RF interference outdoors. Try moving indoors, where there is less RF interference. Keep the units' antennas at least 2'(0.6m) away from conductive objects like metal and water. Overhead telephone lines, fluorescent lighting, and metal fences can all cause interference. Turn off all nearby computers and mobile phones. Make sure there is an unobstructed line of sight between the transmitter's and the receiver's antennas. Keep in mind that your body, clothes, and onstage sets are possible obstructions. Make sure the receiver and the transmitter are within 328'(100m) range. If there are obstructions, you may need to move closer. Turn down the audio input level on your camera or recording device. Lower the audio output level on the receiver. Turn down the gain on your mixer. If there is no adjustment on the device, and the level is still high, adjust the microphone level on the transmitter. Keep this level as high as possible without distortion. Make sure the microphone is as close as to the subject as possible. RF signal is weak. The audio is noisy or distorted. This can include drop outs, white noise, bursts, pops and clicks. The input level on the camera, recorder, or mixer is too high. Too much ambience is being picked up. When using an omnidir-
ectional microphone like the one included with this system, the microphone may be picking up too much ambience. FCC STATEMENT:
