TIPS
• For optimum operation with external antennas, low loss RF shielded cable should be used and the
length of the cable should not exceed 3m.
• The receiver antennas should be kept away from any metal surfaces whenever possible as they
can reflect or shield from the incoming RF signal.
• If the Volume Control of the receiver is set too high, it may over-drive the input of the attached
audio mixer, causing distortion. Conversely, if the output is set too low, the overall signal-to-noise
ratio of the system may be reduced, causing noticeable hiss. If such noise occurs, adjust the
output level of the receiver such that highest sound pressure level going into the microphone
transmitter causes no input overload in the mixer, and yet permit 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 with the correct polarity.
• Before operation please confirm that the receiver and associated transmitter are tuned to the
same frequency group and channel number.
• After making a receiver channel change, please make sure that the corresponding change is also
made on the matching transmitter (per Sections 15 & 19).
• 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.
• Position the receiver such that it has the least possible obstructions between it and the transmitter.
Line of sight is best!
• During operation, the transmitter and the receiver should be as close as possible for optimum
results but never closer than 3’ (1 meter).
• For the best operation, the receiver should be placed at least 1 meter above the ground and 1
meter away from a wall or metal surfaces. The transmitter should be also at least 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.
• Turn the transmitter off when it is not in use. For longest life, remove the batteries if it is not to be
used for a long period (>1 year) as the transmitters draw a tiny residual current even when off to
maintain the programmed settings. Also, since batteries installed for a long time can sometimes
corrode and/or leak, causing damage, it is generally recommend that batteries be removed any-
time the transmitters are not being used.
• When using the UB-1K for instrument use: (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.
