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
together than three feet.
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 angle antennas outward away from the
metal rack.
5. A receiver cannot receive signals from two
transmitters at the same time.
6. The power switch on the transmitter has three
positions: "Off," "Standby" and "On." In the middle
"Standby" position, the transmitter sends only RF to
the receiver; the audio source is turned off.
Notice to individuals with implanted cardiac pacemakers or AICD devices:
Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All wire-
less microphones have low-power transmitters (less than 0.05 watts output) which are unlikely to cause difficulty,
especially if they are at least a few inches away. However, since a "body-pack" mic transmitter typically is placed
against the body, we suggest attaching it at the belt, rather than in a shirt pocket where it may be immediately adjacent
to the medical device. Note also that any medical-device disruption will cease when the RF transmitting source
is turned off . Please contact your physician or medical-device provider if you have any questions, or experience any
problems with the use of this or any other RF equipment.

Ten Tips To Obtain The Best Results

7. For best operation, all the RF Level LEDs should be
lit (maximize RF input); but only the first two or three
AF Level LEDs should be lit (don't overmodulate).
8. 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.
Adjust the output level of the receiver so the highest
sound pressure level going into the microphone
causes no input overload in the mixer, and yet permits
the mixer level controls to operate in their "normal"
range (not set too high or too low). This provides the
optimum signal-to-noise for the entire system.
9. In the UniPak transmitter, the "M" or "G" 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.
