Interference Detection monitors the RF environment for
potential sources of interference which can cause audio
dropouts.
When interference is identified, the RF LEDs illuminate
red and the following warning displays on the receiver
LCD panel.
If the warning display persists or the audio drops out
repeatedly, perform a Scan and Sync at the first
opportunity to find a clear frequency.
High Density Mode
High Density mode creates additional bandwidth for more
channels in crowded RF environments. Frequency
efficiency is optimized by running at 1 mW RF transmit
power and narrowing the modulation bandwidth, allowing
for the channel spacing to be reduced from 350 kHz to
125 kHz. Transmitters can be positioned on adjacent
channels with unsubstantial intermodulation distortion
(IMD).
High Density mode is ideal for applications where many
channels are needed in a confined area, transmission
distances are short, and the number of available
frequencies is limited. Up to 30 meters of range is
available in High Density mode.
