Beam Block Options
The Beam Block Options menu is available only if the transmitter
is connected to a Searchline Excel receiver.
Figure 109. Beam Block menu
If the infrared beam from the Searchline Excel transmitter is
blocked or inhibited in such a way that the intensity of the beam
drops to a level below the readable threshold set by the receiver,
a warning will be generated by the transmitter. The Beam Block
Options menu allows the user to define the maximum period of
time the infrared beam can be blocked and the percentage of
signal loss before generating a warning through the transmitter.
