4. Use the Import button if manually importing firmware files.
5. Click the Update Device tab and check the Version to install box next to
each device.
6. Click Send Updates to load the firmware to the networked devices.
7. When the download is complete, the receiver will reboot with the updated
firmware installed.
Updating the Transmitter
To update transmitters, download firmware to the receiver. You can download
firmware for handheld and bodypack transmitters, or for boundary and
gooseneck transmitters. The receiver sends firmware to the transmitter using
the IR Sync window.

Troubleshooting

Faint sound or distortion
Lack of range, unwanted noise
bursts, or dropouts
Cannot turn transmitter off or change
frequency settings, or can't program

Power
Make sure that the receiver and transmitter are receiving sufficient voltage.
Check the battery indicators. Replace or recharge the batteries if necessary.
Gain
Adjust the system gain on the front of the receiver. Ensure the mic/line switch
setting (XLR output only) on the back of the receiver corresponds to the input
of the mixing console, amplifier, or processor.
Cables
Check that all cables and connectors are fully engaged or locked into position.
Inspect cables for damage. Replace if necessary.

Custom Group IR Sync
1. Press menu while holding the enter button to access the advanced menu.
Use the menu button to navigate to the update menu.
2. The receiver displays the type of transmitter firmware it has available.
The receiver holds one type of firmware at a time.
⁃ HH BP = handheld or bodypack firmware
⁃ BN GN = gooseneck or boundary firmware
3. Press enter to start the update.
4. When the red IR LED flashes, align the receiver and transmitter IR sync
ports. The red LED will remain illuminated to indicate correct alignment
and the download will automatically start.
5. Maintain alignment during the update and monitor download progress
(0 to 100%) on the receiver screen.
6. When the update is complete, "TX Update good" is shown on the receiver
display. If the screen shows Err. 09, update again with a transmitter type
that matches the firmware held by the receiver.
The transmitter and the receiver can be locked to prevent accidental or
unauthorized changes. If a locked control is accessed, the lock icon on the
display will flash. Follow the instructions to unlock the receiver or transmitter.
Firmware Mismatch
Paired transmitters and receivers must have the same firmware version in-
stalled to ensure consistent operation. See Firmware Updates topic for
firmware update procedure.
Encryption Mismatch
Indicates an encryption key mismatch has been detected. Perform an IR
sync between the receiver and transmitter to clear the error.
Custom Group IR Sync
When using Custom Groups, always perform an IR sync from the Custom
Groups menu in the receiver to ensure accurate display of group and channel
information. See Custom Groups topic for additional details.
Radio Frequency (RF)
The blue RF LED will illuminate when a linked transmitter is within range of
the receiver. Measure the transmitter range before a performance to avoid
operating beyond the specified transmitter range.
The RF meter bars indicate 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 the meter shows a signal level when the
transmitter is off, then that channel may have interference. Check the sur-
rounding area for sources of interference or change the receiver to a clear
frequency.
A red RF LED indicates RF overload. Avoid operating multiple systems in
close proximity.
