Please note that this jack acts as the second antenna for diversity reception.
For optimal preformance when a headphone, or the URXL1 lanyard, is not being used it is
recommended that a 3.5mm connector with a piece of wire (approximatally 5 inches long)
connected to the sheild is inserted to act as a second antenna.

1. Battery Compartment - The URX100 uses 3 AA batteries and will work with alkaline, NiMH or
lithium AA batteries.
2. URXL1 Walkie Talkie Lanyard (Optional)-The URX100 can be connected to the remote speaker/mic
port of a walkie talkie. Allowing the user to route the walkie talkie audio left right or center and mix
it with the URX100 audio so both the walkie and URX100 audio can be heard at the same time with
a single pair of headphones.
The URXL1 Lanyard has a push-to-talk button and a microphone to communicate with the walkie

SCAN MENU
Frequency Scan
The frequency scan menu is where the URX100 can scan the user specified frequency range and search for a
clear frequencies. The frequency range will be displayed on the bottom half of the display.
After the scan is completed a graphic display of the RF that is present in that specified range will be shown and
the URX100 will also suggest a clear frequency. That frequency can be accepted by pressing the CH UP key. Or
press the CH DOWN key to skip the first chosen frequency and have the URX100 suggest another frequency.
Scanning for a frequency
•Turn off the transmitter(s).
•From the scan menu press the CH UP key to initiate a scan.
•While the URX100 is scanning, the frequency being examined is
displayed in the bottom half of the screen. Once the scan has
completed a graphic map of the scan will be displayed. The low end of the frequency range is on
the left side and the high end is on the right. Wherever RF is found, a vertical line will be drawn.
The line extends from the baseline up. The length of the line indicates the level or strength of the
found RF at that frequency.
Selecting the frequency
When the scan is complete the URX100 will draw a vertical blinking
line on the display to indicate where the first suggested frequency is,
and the frequency in MHz will appear below the scan graphic.
•Press the CH UP key to accept the new frequency.
•Press the CH DOWN key to decline and suggest a different frequency.

TIME CODE MENU
Mute Time Code Until Jammed
If mute time code is set to on, the time code out of the TA5 is muted and the URX100 will not output any time
code until it receives and locks to the time code that is being sent from the transmitter. This is to prevent
incorrect time code being outputted.
Time Code Output Level
The URX100’s time code output can be adjusted for equipment that needs a specific time code voltage.
The URX100 can output time code from 0.001 to 3.000 Volts.

SETUP MENU
Tone Output
The tone menu allows the URX100 to output tone. This is useful to set levels and check routing. Pressing
the CH UP and CH DOWN keys key will cycle through and output the different tone settings.
•OFF - No tone is being outputted.
•-20dBFS -Tone is outputted at -20dBFS.
•+0dBFS - Tone is outputted at full scale 0dBFS.
Modulation Select
The modulation menu is where the receive format is set. Modulation is simply the way a transmitter
“modulates”, or sends, its signal to the URX100. This setting needs to match the modulation mode that the
corresponding transmitter is set to - if the two setting do not match the URX100 will not be able to receive and
decode the signal from the transmitter.
Modulation types
•STEREO - Select when receiving audio from a Camera Link, Maxx transmitter, or a stereo transmitter.
•ZHD 96 - Select when receiving signal from a ZHD transmitter set to ZHD-96.
•XR MONO - Select when using extended range modulation (XR).
•MONO - Select when using a mono transmitter and XR modulation is not available in the software.
•EU - Select when using a transmitter that is set up for European broadcast standards.
Mute If Unit Code
This menu sets if transmitters with certain ZaxNet unit codes will not be able to be monitored by the URX100.
For example if this menu is set to 30 any transmitter with a ZaxNet unit code below 30 will not be able to be
monitored by the URX100.
If a muted preset is selected to be monitored “MUTE” will appear on the display and that preset will not be able
to be listened to - even if that preset is enabled.

Software Update
This menu is where the URX software is updated from.
When in this menu pressing the CH UP key will initiate the update process and the URX100 will wait and search
for software that will be transmitted from a Zaxcom transmitter (please refer to the software update section of
this manual for more information on how to update the URX100.)
IFB voting
The IFB voting feature will allow the URX100 to automatically switch to a secondary frequency when it loses its
signal from the primary transmitter. One purpose of this is, on a large set, a second transmitter can be placed
at a distant location, so if the URX100 loses the signal from one transmitter it will automatically switch to the
other transmitter.
To use IFB voting just set the offset in this menu to (200 KHz, 300 KHz, 400 KHz or 500 KHz). Then set the
second transmitters frequency to the primary frequency + the offset. So for example if the primary frequency
is 560.000 MHz and the offset is 200 KHz then the second transmitter should be set to 560.200 MHz
Audio Delay Set
The audio delay menu sets a variable delay to the output audio. A delay is useful if the ERX is being used for
personal monitoring and there is a video processing delay to the monitors - so engaging the delay will delay the
audio to match the video. The audio delay can be adjusted from 1MS to 400MS in 1MS increments.
Display Flip
The display flip menu changes the orientation of the display for when the unit will be inverted.

Hide Encryption Menu
This menu allows for the encryption menu to be hidden preventing accidental changes.
•HIDDEN - The encryption menu does not appear when cycling through the menu settings.
•SHOW - The encryption menu will appear.
Encryption Code Set
This menu is where the encryption is turned on and the code is set. This code needs to match the encryption
code of the associated transmitter(s). If an encryption code is set on the transmitter the transmitted audio will
be encrypted and can only be listened to if the URX100 has the same matching encryption code entered. When
the codes do not match, all that will be heard is white-noise.
These two sets of numbers are formed into a single six-digit encryption code which provides a total of
16,777,216 possible combinations. For non-encrypted operations all six numbers should be set to 0.
Adjusting the encryption code
1. Press the menu key to cycle to the next character.
2. To change the designated character, press the CH UP or CH DOWN key.

Headphone Out
The headphone out is a 3.5mm TRRS connector. The URXL1 walkie lanyard uses all 4 connectors, but any standard
headphone can be used to listen to audio.
Please note that the when a headphone, or the optional URXL1 Lanyard, is being used its wire becomes the second
antenna for the URX100 giving it diversity reception. It is recommended that when no headphone, or lanyard, is
connected to the 3.5mm jack a 3.5mm plug with a short piece of cable (approximately 5 inches long - wired only to
the shield) should be connected for better reception.
