OPERATING FREQUENCY ADJUSTMENT
The detector has 250 independent frequency channels (1-250) available. The difference in
frequency between adjacent channels is 1 MHz. The complete range of available channels
comprises 24.001-24.250 GHz. The nominal operating frequency of channel 1 is 24.001 GHz, that
of channel 10 is 24.010 GHz, and that of channel 250 is 24.250 GHz. The selection of a frequency
channel is made with the help of tuning software. For proper operation of the detector, it is
essential to specify the same frequency channel for both the transmitter unit and the receiver unit.
The following frequency channel-related operational practicality must be taken into account when
installing multiple detectors in close physical proximity to one another, e.g., in a parallel
configuration: Although the nominal transmission frequency of a given transmitter unit may be –
for example – 24.150 GHz, its signal is receivable within an actual frequency range of 24.144-
24.156 GHz.
It is therefore recommended that, in multiple-detector configurations, the operating frequency
channels of the detectors be set as far apart as possible by spacing them at generous intervals
across the entire available (1-250) channel range.
