TRANSMISSION RANGE
When using the MINDA system over a line-of-sight path, a range of greater than 100 yards is
likely, whereas in a busy street, hotel, or indoors the range will be less.

GETTING THE BEST RESULTS WITH MINDA
To maximize the effectiveness and communications range of a 'MINDA' alarm system there are
some simple 'tricks' that really do work and which, on all occasions when it is practical and
convenient to use them, can be used to enhance its performance. These are....

• When carrying and using the 'MINDA' receiver, try to allow the antenna wire to hang freely from
the receiver case and also remember that audible warnings from the built-in 'beeper' may be
somewhat muted if the small hole on the label side of the unit is significantly obstructed.

• Remember that the human body is largely comprised of water. When using a transmitter, face
in the direction of the receiving location so that your own body does not obstruct the emitted radio
signal. If possible, hold the transmitter away from your body so that there is free space around its
antenna. NEVER shorten or wrap up the transmitter antenna wire.

• When using a 'MINDA' transmitter or receiver inside a vehicle, try to ensure that its antenna is
kept above the window line to ensure that signal levels are maximized.

• If you are in the street and communications get difficult, try holding the unit just above the roof
of a parked car with the antenna wire pointing upwards. By doing this the metal roof of the vehicle
will act as a counterpoise earth and so enhance the signals
