installed to ensure consistent operation. See Firmware Updates topic for
firmware update procedure.
Encryption Mismatch Indicates an encryption key mismatch has been detected. Perform an IR
sync between the receiver and transmitter to clear the error.
Custom Group IR Sync When using Custom Groups, always perform an IR sync from the Custom
Groups menu in the receiver to ensure accurate display of group and
channel information. See Custom Groups topic for additional details.
Radio Frequency (RF) The blue RF LED will illuminate when a linked transmitter is within range of
the receiver. Measure the transmitter range before a performance to avoid
operating beyond the specified transmitter range.
The RF meter bars indicate amount of RF power being received. This signal
could be from the transmitter, or it could be from an interfering source,
such as a television broadcast. If the meter shows a signal level when the
transmitter is off, then that channel may have interference. Check the
surrounding area for sources of interference or change the receiver to a
clear frequency.
A red RF LED indicates RF overload. Avoid operating multiple systems in
close proximity.
Frequency
Compatibility
Perform a Scan and Sync to ensure the transmitter and receiver are set
to the same channel or frequency
Look at the label on the transmitter and receiver to make sure they are
in the same band (G50, J50, L50, etc...).
Reducing Interference Perform a scan to find the best open frequency. Perform an IR sync to
transfer the settings to the transmitter.
For multiple systems, make sure that each receiver is assigned to a
unique channel. Interference will occur if two transmitters are set to the
same channel.
Maintain a line of sight between transmitter and receiver antennas.
Move receiver antennas away from metal objects or other sources of
RF interference (such as CD players, computers, digital effects, network
switches, network cables and Personal Stereo Monitor (PSM) wireless
systems).
Eliminate RF overload (see below).
Increasing Range Increase transmitter RF power level to Hi
Use an active directional antenna, antenna distribution system, or other
antenna accessory to increase RF range
Eliminating RF Overload If the RF OL icon appears on the RF meter, try the following:
Reduce the transmitter RF power level from Hi to Lo
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
