1. Use only fresh alkaline batteries. Do not use "general
purpose" (carbon-zinc) batteries.
2. Position the receiver so that it has the fewest possible
obstructions between it and the normal location of the
transmitter. Line-of-sight is best.
3. The transmitter and the receiver should be as close
together as conveniently possible, but no closer than
three feet (1 m).
4. The receiver antennas should be in the open and away
from any metal. If mounted in a rack, have the unit on
top, or use an ATW-RA1 kit to front-mount the antennas.
5. The transmitter and receiver must be set to the same
channel number.
6. A receiver cannot receive signals from two transmitters
at the same time.

7. If the AF Level control of the receiver is set too high, it
may over-drive the input of the mixer or clip the output of
the receiver, causing distortion. Conversely, if the receiver
output is set too low, the overall signal-to-noise ratio of
the system may be reduced. Please see Setting Levels
section, pages 7 and 8.
8. You need to change channels when a strong interference
signal is received (a strong RF signal is shown with the
transmitter off).
9. In the UniPak transmitter, the microphone level trim or
instrument level trim input control not in use should be
set to minimum.
10. Turn the transmitter off when not in use. Remove the
battery if the transmitter is not to be used for a period of
time.
