Encryption Mismatch
Custom Group IR Sync

Reducing Interference
Increasing Range
Indicates an encryption key mismatch has been detected. Perform an IR sync
between the receiver and transmitter to clear the error.
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.
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.
•
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...).
•
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).
•
Increase transmitter RF power level to Hi
•
Use an active directional antenna, antenna distribution system, or other
antenna accessory to increase RF range
