Frequency Band
Most countries closely regulate the radio frequencies used in the transmission of
wireless information. These regulations state which devices can use which
frequencies, and help to limit the amount of RF (radio frequency) interference in all
wireless communications. The DHXR4 offers 120 selectable channels within either
the 584-607MHz (Code D), 655-679MHz (Code L) or 518-535MHz (Code N) frequency
ranges.
To facilitate system setup and protect against RF interference, each system comes
with multiple predefined frequency groups and channels. When using a single
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.
