VR2Tx Quick Guide
Place VR2Tx on clean, stable surface so hydrophone hangs off edge. We
recommend working in a controlled environment.
Insert one steel rod into the Attachment hole and other one in the Bluetooth
Activator Hole on the end-cap and hold on to the rods.
Apply pressure to the rod in the Bluetooth Activator Hole to turn end-cap
counter-clockwise when you are facing the hydrophone. Remove rod when
end-cap turns easily and continue turning by hand.
Slide end-cap and cylinder apart until the battery
compartment has cleared the cylinder. Be very
careful not to damage the threads on the end-cap
or the VR2Tx won’t close and seal properly.
Open Case
Electronics inside the case
must
NEVER come in
contact with any water or
the VR2Tx will be damaged.
The battery is held in the battery compartment by a plastic pin spanning the opening. Remove
the thin O-ring before removing the pin (O-ring holds pin in place). Downward force on battery
may be needed to allow pin to move.
Battery
The battery is connected to VR2Tx on the side of the case. When
installing the battery, listen for a “click” and watch that light flashes
four times and then twice quickly every 5 seconds. When
disconnecting battery, press the release tab on the
battery connector and then
pull connector halves apart.
This VR2Tx Quick Guide provides information on key VR2Tx
procedures. Full details for all VR2Tx procedures are found
in the VR2Tx User manual and at www.vemco.com. We
strongly recommend you study the full user manual before
using this quick guide.
Make sure the two O-rings in the end-cap, and the
corresponding O-ring surface inside the Outer
Cylinder, are clean and debris-free. If the VR2Tx
has previously
been deployed,
replace the
O-rings.
O-rings
Doing so may damage the receiver and render
it unable to detect transmitters.
Do not bump the VR2Tx
hydrophone or expose it to
extreme temperature variations.
TIP: Write the date on the battery.
Close Case
Close the VR2Tx case by doing the reverse of opening it, but
first
put a new desiccant pack in the bottom of the tube.
Slide the battery end into the Outer Cylinder. Rotate the end-
cap clockwise, using
the steel bars when
needed.
Stop turning when the
gap between the two
halves is closed.
Over tightening could
damage the case.
A desiccant pack helps
reduce the occurrence of
condensation in the VR2Tx

Slide the smaller end of the
Bluetooth Activator in the
Bluetooth Activator Hole on the
VR2Tx, near the hydrophone.
Wait until the VR2Tx’s LED
begins flashing a bright, long,
steady flash once a second.
The wait time is less than five
seconds.
Remove the Bluetooth
Activator.
Activate
One bright red flash
every second
Status Light
No flashes = no power
2 quick red flashes every 5 sec = in Recording Mode
2 quick red flashes every 10 sec = memory is full
1 quick red flash = acoustic ping received
1 bright, long red flash = detection written to memory
1 long red flash/sec = ready for
Bluetooth communication
On (solid red) = communicating with VUE
One short green flash = acoustic ping was transmitted
One long green flash = transmitted pings written to memory

Operating temperature: -5 °C to 40 °C; Water in
which the VR2Tx is deployed must not freeze
.
Static depth rating: 500 meters (730 psi)
Attachment
Around Rope
Through Rope
Around Rope
Through Rope
The common method used to attach a VR2Tx
receiver to a mooring line is to use five cable ties
(zip tie or tie-wrap) with the following characteristics:
•388 mm (15.25") long
•7.5 mm (0.3") wide
•UV protected
•120 lb tensile strength
Open the “wrap in the rope” to
pass the cable tie through the rope.
Avoid shadowing or blocking the receiver with your mooring equipment. Line of sight is a must!
Suggested minimum: 3/8" diameter nylon rope
Basic instructions for communicating acoustically
with a VR2Tx while deployed are found in the
receiver Field Communication Quick Guide.
Open VUE and wait while software
scans for the activated VR2Tx. If it
doesn’t scan, then click the “Device
Scan” button.
After VR2Tx is located, double-click on
the receiver icon with the correct serial
number to open communication and
display receiver information.
VR2Tx Status Light is continuously on
during communication.
Bluetooth Communication
Bluetooth only works through air.
Actions such as starting a study, offloading data, and ending communication are performed from the Receiver tab and
are started by selecting the correct icon in the tab’s ribbon. Details are found in the VR2Tx user manual.
VUE Software
Close View –ends
communication with VR2Tx
and closes Receiver tab.
Receiver resumes recording
(does not initialize).
Start Recording –setup and
begin a study; also erases
VR2Tx memory
Offload data
–choose to offload all data or just new data.
Device Options –change Transmit Profile, logging
options, or setup a Watch Table
