TIPS • If the Volume Control of the receiver is set too high, it may overdrive the input of the mixer, causing distortion. Conversely, if the output is set too low, the overall signalto-noise ratio of the system may be reduced. Adjust the output level of the receiver such that the highest sound pressure level going into the microphone causes no input overload in the mixer, and yet permist 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. • Do not place the receiver antennas within 3 feet (1 meter) of another receiver or antennas. • The receiver antennas should be kept away from any metal surface. • For the best operation, the receiver should be placed at least 3 feet above the ground and 3 feet away from a wall or metal surfaces. All operating transmitters should be also at least 3 feet from the U-81 OCTAVO receiver. Keep antennas away from noise source such as motors, automobiles, neon light, signal processor, computer, as well as large metal objects. • A single receiver cannot receive signal from two or more transmitters on the same frequency simultaneously. • For operation with an external antenna, low loss RF shielded cable should be used and the length of the cable should not exceed 10 feet (3 meters). • 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 never less than 1 meter. • 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. Do not mix and use new and old batteries together. • Turn the transmitter off when it is not in use. Remove the batteries if it is not to be used for a long period. • Headset and lavalier mic users, note that the microphone element can easily be destroyed by the buildup of salts and minerals from perspiration and saliva. It is good practice to put a windscreen on the mic at all times to protect it. 11
