3.0 Flexx Configurations
The Flexx ultrasound unit offers multiple configurations for scanning multiple species of
livestock, horses, exotic animals and pets.
The optional Flexx protective sun-shaded carry case allows for outdoor use in sunny
conditions. This carry case works with Ram Mount accessories for mounting at a cattle chute and
equine stocks. Make sure you discuss the various Flexx mounting configurations that you may
be interested in with your ReproScan representative.

4.0 Operating Conditions
The Flexx ultrasound unit is splash proof and can operate in moist conditions and in most
temperatures that are encountered in veterinary practice. When operating the Flexx in wet
conditions care must be taken to avoid moisture entering the Flexx. Keeping the Flexx in a
backpack and using an external viewing device, is one option for rainy days. On extremely cold
days, the Flexx should be kept at 10˚C or 50˚F. As the Flexx generates considerable heat, keeping
the Flexx in a backpack and using an external viewing device will allow ideal operation on cold
days. Flipping the Flexx screen when inside the sunshade case is an ideal option to protect the
ports from falling particles and moisture while mounted chute side.
Please contact the ReproScan office if you have questions regarding the use of the Flexx
ultrasound in challenging conditions.

Attention: The grid power (main voltage) may be above or below the
optimum range of 110V AC 60Hz to 240 V AC 50Hz in some rural areas. Please
ensure that the grid power is suitable for charging electronics.
Warning: Do not operate the Flexx ultrasound unit if there is any visible or
suspected damage to electrical wires or connector cables. Contact ReproScan
Technologies, LLC if you have questions about the safe operation of this
equipment.
Attention: Do not operate the Flexx ultrasound unit is extreme weather
conditions such as thunderstorms, heavy rainfall, extreme heat and extreme

5.0 Connecting Ultrasound Probes, Viewing Devices and Power
Always use care when connecting probes, viewing devices and power to your Flexx ultrasound
unit. ReproScan uses rugged connections in the construction of its ultrasound equipment but care
must be taken to prevent accidental damage to the probe connectors, LEMO goggle connector and
the power connector.
Attention: Always turn the Flexx ultrasound unit OFF before connecting or
disconnecting ultrasound probes, viewing devices and power cables.
5.1 Connecting an Ultrasound Probe
Turn off the Flexx Module before connecting a probe. Before trying to connect a probe
to the Flexx module, carefully examine the connector plug on the probe (male connector) and the
socket on the Flexx module (female connector). Identify the marker on the probe’s male
connector and the marker on the Flexx module. These are important features that will allow you
to connect the probes to the Flexx module without any problems. Once you have identified these
structures and the slot in the female socket, carefully insert the probe’s male connector into the
socket on the Flexx module. Once fully inserted, tighten the probe into the socket by turning the
sleeve on the probe connector clockwise.
5.2 Disconnecting an Ultrasound Probe
Turn off the Flexx Module before disconnecting a probe. Turn the sleeve counter-
clockwise to loosen the probe connector. The firmly pull the probe connector out of the Flexx
probe socket. Ensure that probe connectors are protected from physical damage during
transportation. Ensure that probe connectors are completely dry before storage so no corrosion
can occur.

Page 13
5.3 Vista Goggles Installation
Turn off the Flexx Module before connecting Vista Goggles. Before trying to connect
Vista Goggles to the Flexx module using the LEMO, carefully examine the connector plug on the
Vista Goggles (male connector) and the socket on the Flexx module (female LEMO connector).
Identify the red marker on the Vista’s male connector and the red marker on the Flexx module.
These are important markers that will allow you to connect the Vista Goggles to the Flexx module
without any problems. Once you have identified these structures, carefully insert the Vista’s male
connector into the socket on the Flexx module. Note that there is a sleeve that slides on the
Vista’s male connector. You will need to gently pull back on this connector to remove the male
LEMO connector from the Flexx module’s female LEMO connector.
Male LEMO Connector with Red Marker Female LEMO Connector with Red Marker
5.4 NFI 5000 Monocular Installation
Your NFI 5000 monocular viewing device uses the same LEMO connector as the Vista
goggles. Follow the instructions above to connect the NFI 5000 to the Flexx Module. The NFI
5000 requires a Composite NTSC (TV) signal to operate. To change the signal from VGA
(standard) to TV, follow these instructions:
When in regular scanning mode, press the Measure key three times, press the Enter key
three times. Use the Arrow keys to change the Video signal to TV.
5.5 Connecting the Flexx to a ReproScan 2.0 Wireless Monitor
1. Set the RF according to the instructions in section 6.3.8.2 of this manual and select the RF
channel, such as "RF: 1";
2. Turn on the ReproScan 2.0 wireless monitor;
3. Make sure that the monitor is set to Wireless;
3. To set the channel on the wireless monitor to correspond to the wireless signal on the Flexx.
Eg. RF1 on Flexx matches Channel 1 on 2.0 ReproScan wireless monitor.
5.6 Connecting the Power to the Flexx Module
Turn off the Flexx Module before connecting the Power Adapter to the Flexx.
1. Lift the protective cover over the 2.5 mm female jack on the Flexx module.
2. Insert the 2.5 mm jack from the power adapter into the Flexx module.
3. Make sure that the adapter is an approved ReproScan 12.8 VDC 3.0 Amp
approved power supply.
