What is Happening Possible Why

What to Do

Faulty data cable

Check the data cable for short
circuits and ensure that it is
properly connected to the
primary transmitter and to the
RangeBooster transmitter

No audio signal at
primary transmitter

Check that the primary
transmitter´s transmit light is
lit and that the primary
transmitter is receiving an
audio signal

RangeBooster
transmit light does
not light

Faulty AC adapter
or faulty power outlet

Check the power outlet and
the AC adapter; if possible,
check for correct voltage of
the AC adapter

RangeBooster
transmitter not tuned

Tune the RangeBooster
transmitter as described on
page 4

Faulty data cable

Ensure that the data cable
has the correct impedance
and is not damaged

Data cable too long

Shorten the length of the data
cable if possible

Poorly chosen
location of
RangeBooster
transmitter

Relocate the RangeBooster
transmitter or primary
transmitter as described on
page 2

Crackling noise,
audio distortion or
dropouts at
headphones or
receiver after the
RangeBooster
transmitter is
powered up,
especially when
moving the
headphones or
receiver

Strong interference

In some cases, there may be
strong interference preventing
proper reception of the audio
signal which can be caused
by microwave ovens, cordless
telephones, wireless networks
or video transmitters. Either
eliminate the interference or
relocate the RangeBooster
transmitter or primary
transmitter.

Poorly chosen
location of
RangeBooster
transmitter

Relocate the RangeBooster
transmitter or primary
transmitter as described on
page 2

Range does not
improve by using
RangeBooster
transmitter
