Shure QLXD2 Manual

• 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
Error Codes and Solutions
Error codes are generated when the receiver detects a condition that can
potentially affect system performance.
If an error is displayed on the receiver, use the following table to identify the
problem and find the corresponding solution.
