Error Codes And Solutions - Shure QLX-D Series Manual

QLX-D Wireless System
• 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

Solutions
Update transmitter and receiver firmware
to the latest version.
Set encryption to off for components from
different Shure products lines, such as
QLX-D and ULX-D.
Perform an IR sync between the
transmitter and receiver to clear the error.
Receiver and transmitter are operating in
overlapping frequencies from different
bands.
Receiver and transmitter are from bands
that do not share compatible frequencies.
Rescan, select a different group, or use
WWB to find a frequency.
Update firmware on the transmitter and
receiver.
Check that battery is firmly installed into
the battery compartment. If condition
persists, replace the battery.
To complete the firmware update, match
the type of transmitter to the type of
firmware the receiver currently has.
