TROUBLESHOOTING
Because of the widespread use of wireless technology, many RF signals pervade our environment. This can sometimes make it
challenging to work with a wireless system like the ULW-16. In some cases, you may be doing everything correctly and still be
experiencing some difculties. Included in this troubleshooting guide are some tools and tips for dealing with RF signals and interference.
Problem Possible Cause Solution Comment
The audio
is noisy or
distorted. This
can include
drop outs, white
noise, bursts,
pops, and clicks.
RF interference Try a different channel. Make sure both units are on
the same channel.
Try to position the antennas at a 45° angle in relation
to each other.
There can be a lot of RF interference outdoors. Try
moving indoors, where there is less RF interference.
Keep the units’ antennas at least 2′ (0.6 m) away
from conductive objects like metal and water.
Overhead telephone lines, uorescent lighting, and
metal fences can all cause interference.
Turn off all nearby computers and mobile phones.
RF planning and management is important when
using a UHF system. Test your RF environment
before recording. To do this, turn on only the
receiver. If there is noise or the RF LED is glowing,
then there is interference on this channel and you
should avoid using it.
Refer to www.fcc.gov/fcc-bin/audio/tvq.html to
nd out what frequencies are being used in your
area by radio and TV stations, so you can avoid
these frequencies.
Receiver overload If the antennas are too close, it can cause receiver
overload (intermodulation). Make sure the antennas
are at least 3′ (0.9 m) away from each other.
