Interface Locks; Encryption Mismatch; Tx Battery Hot; Radio Frequency (Rf) - Shure ULX-D Manual De Instrucciones

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 sour­
ces 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...).
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 receiver antennas away from metal objects or other sources of RF interference (such as CD players, computers, di­
gital 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 an active directional antenna, antenna distribution system, or other antenna accessory to increase RF range.
