Frequency Band
Most countries closely regulate the radio frequencies used in the transmission of
wireless information. These regulations state which devises can use which frequencies,
and help to limit the amount of RF (radio frequency) interference in all wireless
communications. The DHTRQUAD offers 120 selectable channels within either the 584-
607MHz (Code D) or 655-679MHz (Code L) frequency ranges.
To facilitate system setup and protect against RF interference, each system comes with
m u l t i p l e p r e d e f i n e d f r e q u e n c y g r o u p s a n d c h a n n e l s . W h e n u s i n g a s i n g l e
receiver/transmitter, the operating frequency will generally not have to be changed. In
an installation with multiple receivers/transmitters, each set must operate on a separate
channel from the others. The group and channel system provides an optimum frequency
spread when using multiple receiver/transmitter systems.
