TR OUBLESHOOTING
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-96. Each system that is added in simultaneous operation increases the potential for
intermodulation and requires more diligence in RF planning and management. In some cases, you may be doing everything correctly and still
be experiencing some difficulties. 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, fluorescent 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
find out what frequencies are being used in your
area by radio and TV stations, so you can avoid
these frequencies.
The batteries are
weak. Replace or recharge the batteries in the receiver and
transmitter. Make sure to bring extra batteries with you.
You should replace the batteries on every shoot.
