Fig 2: WLT-02 TRANSMITTER
Installation:
The maximum transmission distance can vary depending on
several factors, including how much WI-FI traffic is taking place in
the space at any given time and how much iron and steel is
nearby. The rule of thumb is a maximum of 100’ (30 m) through
the space at any given time and how much iron and steel is
nearby. The rule of thumb is a maximum of 100’ (30 m) through
walls and 150’ (45 m) outdoor in direct line of sight. In certain
instances this system will encounter so much interference it may
not work at all. We always suggest experimenting to see if it will
work satisfactorily.

Move the switch on the rear of transmitter two clicks right to the
ON position. Turn the WRA-50 amplifier power switch to the on
position. If this transmitter is the only one in the area, change the
ON position. Turn the WRA-50 amplifier power switch to the on

In most stand alone systems we suggest starting with channel 25,
as this is at the high end of the WI-FI band and is generally less
used by other WI-FI users. If a great deal of interference is

used by other WI-FI users. If a great deal of interference is
detected this system is designed to temporarily mute or “dip out”.
If this happens repeatedly, try experimenting with other channels.
