8. User Must Know
8.1 Precautions of Transmitter
> Please connect the antenna to transmitter first, then turn on the power and do other
operations afterwards.
> The working voltage of the transmitter need to connect the 12V adapter , otherwise the
transmitter could be damaged if the voltage is incorrect .
8.2 About Transmission Distance
>Transmission range is greatly affected by the local RF environment, antenna type, power
setting, frequency setting and receiver sensitivity. If the transmission range is short, you may
need to upgrade the antenna to higher gain, or install the antenna on places at higher
altitude.
>Generally speaking, a antenna brings up a transmission distance of around
2-5KM .Please contact us for more and better transmission proposals.
8.3 About sound quality
>Please keep line-in volume under 50% and adjusted to a proper level when inputting into
machine.
>If the input audio sources (such as audio from computer) include bass enhancement mode
or treble enhancement mode, please adjust the volume of transmitter to lower level, because
there is an audio amplifier built-in inside the transmitter, thus the audio output is of high
quality without distortions.
>To ensure better listening experience, please adjust the output volume level of transmitter
to a matching grade with that of other local radio stations.
