Power
Make sure that the receiver and transmitter are receiving sufficient voltage. Check the battery indicators and replace the trans­mitter batteries if necessary.

Gain
Adjust the system gain on the front of the receiver. Ensure the output level on the back of the receiver corresponds to the mic/line input setting of the mixing console, amplifier, or DSP.

Cables
Check that all cables and connectors are working correctly.

Interface Locks
The transmitter and the receiver can be locked to prevent accidental or unauthorized changes. A locked feature or button will produce the Locked screen on the LCD panel or the lock icon will flash on a transmitter.

Encryption Mismatch
Re-sync all receivers and transmitters after enabling or disabling encryption.

Firmware Mismatch
Paired transmitters and receivers must have the same firmware version installed to ensure consistent operation. See Firmware topic for firmware update procedure.

Tx Battery Hot
If the transmitter battery does not cool off, the transmitter will shut down. Let the device cool down and then consider swapping the transmitter battery to continue operation.
Identify any possible external heat sources to the transmitter and operate the transmitter away from those external heat sources.
All batteries should be stored and operated away from external heat sources in reasonable temperature conditions for best performance.

Radio Frequency (RF)

RF LEDs
If neither blue RF Diversity LED is illuminated, then the receiver is not detecting the presence of a transmitter.
The orange RF Signal Strength LEDs indicate the 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 more than two of the orange RF LEDs are still illuminated while the transmitter is off, then that channel may be experiencing interference, and you should try a different channel.

The red RF LED indicates RF overload. Overloads have the potential to cause interference in multiple system installations. If you are experiencing an overload, turn off the receiver to see if it is causing interference with other components.
The numerical channel select button also turns red to indicate interference.

• Dim red = Channel is not selected, experiencing interference
• Bright red = Channel is selected, experiencing interference

Compatibility

• Perform a Scan and Sync to ensure the transmitter and receiver are set to the same group and channel.
• Look at the band label on the transmitter and make sure the receiver is set to the same band.

Reducing Interference

• Perform a group or channel scan to find the best open frequency. Perform a sync to transfer the setting to the transmitter.
• 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, comput­ers, 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.
