Transmitter battery hot message
Power
Make sure that the receiver and transmitter are receiving sufficient voltage. Use the 15 V DC power supply furnished with the
ULXD4 receiver. 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 (XLR output only) on the back of the receiver corre
sponds to the input 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.
Encryption Mismatch
Re-sync the receiver and transmitter after enabling or disabling encryption.
Note: Encryption is not configurable for all units.
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 amber RF Signal Strength LEDs indicate the amount of signal 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 one or two of the amber RF LEDs are
still illuminated while the transmitter is off, then that channel has too much interference, and you should try a different channel.
The red RF LED indicates RF overload. This will usually not cause a problem unless you are using more than one system at
the same time, in which case, it can cause interference in the other system.
Compatibility
•
Perform a Scan and Sync to ensure the transmitter and receiver are set to the same group and channel.
•
Look at the label on the transmitter and receiver to make sure they are in the same band (G50, J50, L50, etc...).
