For multiple systems, check that all systems are set to channels in the same group (systems in different bands do not
need to be set to the same group).
Maintain a line of sight between transmitter and receiver antennas.
MoveorpointreceiverantennasawayfrommetalobjectsorothersourcesofRFinterference(suchasLEDwalls,comput
ers, digital effects, network switches, network cables and Personal Stereo Monitor (PSM) wireless systems).
Eliminate RF overload (see below).
Increasing Range
If the transmitter is more than 6 to 60 m (20 to 200 ft) from the receiver antenna, you may be able to increase range by doing
one of the following:
Reduce interference (see above).
Increase transmitter RF power level.
Use Normal mode instead of High Density mode.
Use an active directional antenna, antenna distribution system, or other antenna accessory to increase RF range.
Eliminating RF Overload
If you see the red RF LED on a receiver, try the following:
Reduce the transmitter RF power level
Movethetransmitterfurtherawayfromthereceiver—atleast6m(20ft)
If you are using active antennas, reduce antenna or amplifier gain.
Use omnidirectional antennas
Antenna Faults
The Antenna Fault red LED indicates a short circuit condition or excessive load at an antenna port.
Check antennas and cables for damage
Ensure that antenna ports are not overloaded
Check antenna bias voltage setting. Turn off voltage if using passive antennas.
Clean Battery Contacts
Clean the battery contacts with an electrical contact cleaner designed for gold contacts and safe on plastics.
