Issue
Antenna Fault Red LED
Handheld transmitter shuts down during use
Power
Make sure that the receiver and transmitter are receiving sufficient voltage. Check the battery indicators and replace the trans
mitter 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 transmit
ter, 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.
