Points worth bearing in mind!
•
Other wireless equipment operating on the same frequency
band may reduce the range of the product.
•
The range of all wireless equipment is affected by obstacles
between the transmitter and the receiver (a concrete wall
reduces the signal far more than a plasterboard partition,
for example).
If you are having problems with the operation of
the system, try the following solutions
•
Switch off any other wireless equipment to check whether it
could be causing the problem.
•
Move the wireless equipment and/or reduce the distance,
and reduce the number of obstacles (walls, furniture, etc.)
between the transmitter and the receiver.
