TIPS • The receiver antennas should be kept away from any metal surface. • If the Volume Control of the receiver is set too high, it may over-drive the input of the mixer, causing distortion. Conversely, if the output is set too low, the overall signal to noise ratio of the system may be reduced. Adjust the output level of the receiver such that highest sound pressure level going into the microphone causes no input overload in the mixer, and yet permits the mixer level control to operate in the normal range (not too high and not too low). This provides the optimum signal to noise for the entire system. • Before inserting the batteries, please make sure that they are inserted according to the correct polarity. • Use only brand new alkaline batteries. Do not use "general purpose" batteries. When batteries are weak, replace the batteries altogether at the same time. • Position the receiver such that it has the least possible obstructions between it and the transmitter. Line of sight is best! • The transmitter and the receiver should be as close as possible but not less than 3 feet (1 meter). • For the best operation, the receiver should be placed at least 3 feet (1 meter) above the ground and 3 feet (1 meter) away from a wall or metal surfaces. The transmitter should be also at least 3 feet (1 meter) from the receiver. Keep antenna away from noise source such as motors, automobiles, neon light, signal processor, computer, as well as large metal objects. • A receiver cannot receive signal from two or more transmitters simultaneously. The U-41 has two receivers so can be operated with two transmitters only on the same frequencies. • Turn the transmitter off when it is not in use. Remove the batteries if it is not to be used for a long period. Note: Scratchy noises can sometime occurs when some electric guitars with dirty pots or connections are used with any wireless system. Therefore, the supplied capacitor provides first order filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still give you scratchy noises, we suggest these steps to eliminate them: a. Make sure all guitar volume and tone pots are clean and all contacts are solid- this is very important. b. A 47pF capacitor soldered across the pot to ground terminal of the guitar's volume and tone pots will provide extra filtering. 12
