Vemco VR2W User manual

This VR2W Quick Guide provides basic information on key
VR2W procedures. Full details for all VR2W procedures are
found in the VR2W User manual. 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 VR2W has
previously been deployed, replace the O-rings.
O-rings
Do not bump the VR2W hydrophone or
expose it to extreme temperature variations.
Doing so may damage the receiver and render it
unable to detect transmitters.
Place VR2W on clean, stable surface so hydrophone hangs o 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 VR2W won’t close and seal
properly.
Open Case
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.
The battery is connected to VR2W on the side of the case. When installing
the battery, listen for a“click” and watch that light ashes 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.
Main Battery
Close the VR2W case by doing the reverse of opening it, but
first put one new desiccant pack in the bottom of the tube.
Slide the at 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.
NOTE: Dessicant
packs help reduce
the occurrence of
condensation in the
VR2W.
Close Case
Electronics inside the case must NEVER come
in contact with any water or the VR2W will be
damaged.
TIP: Write the date on the battery.

Quick Reference Guide

Slide the smaller end of the
Bluetooth Activator in the
Bluetooth Activator Hole on the
VR2W, near the hydrophone.
Wait until the Status Light begins
ashing a bright, long, steady ash
once a second. The wait time is
less than ve seconds. Remove the
Bluetooth Activator.
Activate Bluetooth
The common method used to attach a VR2W receiver to a
mooring line is to use ve 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!
Attachment
Suggested minimum: 3/8” diameter nylon rope
Open VUE and wait while software scans
for the activated VR2W. If it doesn’t scan,
then click the “Device Scan”button.
When VR2W appears, double-click on
the receiver icon with the correct serial
number to open communication.
VR2W Status Light is continuously on
during communication.
Connect to VUE
Bluetooth only works through air.
One bright ash
every second.
Actions such as starting a study, ooading 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 VR2W user manual.
VUE Software
Close View – ends
communication with VR2W and
closes Receiver tab. Receiver
resumes recording (does not
initialize).
Update rmware – Always update the rmware to
the latest available from the VEMCO website. Ooad data – choose to ooad all data or just new data.
Start Recording – setup and
begin a study; also erases VR2W
memory
Basic instructions for communicating acoustically
with a VR2W while deployed are found in the Receiver
Field Communication Quick Guide.
Operating temperature: -5 °C to 40 °C; Water in
which the VR2W is deployed must not freeze.
Static depth rating: 500 meters (730 psi)
No ashes = no power
2 quick red ashes every 5 sec = in Recording Mode
2 quick red ashes every 10 sec = memory is full
1 quick red ash = acoustic ping received
1 bright, long red ash = detection written to memory
1 long red ash per sec = ready for Bluetooth communication
On (solid red) = communicating with VUE
Status Light
