Configuring and Installing the Activator

Resizing the Activation Field
The area of Tag activation can be controlled by adjusting the size of
the activation field. For example, you may want to shrink the
activation field for a Picture-Frame antenna to concentrate the field
near a doorway, preventing activation of tags further up the hall.
Note: Each Activator is shipped from the factory with its activation
control adjusted to its highest level.
Adjusting the Field
The size of the activation field is controlled by the TX CNTL screw on
the back of the Activator (Figure 15). The screw can turn in one
direction 30 times. After it has been turned 30 times in one direction,
it will make a soft clicking sound. The clicks indicate that continuing
in this direction will no longer have an effect on the field’s size. When
you hear this sound, the wake-up field has been adjusted to one
extreme or the other.
