Vemco VR2Tx User Quick Reference Manual

This VR2Tx Quick Guide provides basic information on key
VR2Tx procedures. Full details for all VR2Tx procedures are
found in the VR2Tx User manual. We strongly recommend you
study the full user manual before using this quick guide.
Open Case
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.
Main Battery
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.
O-rings
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.
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.
VR2Tx Receiver

Quick Reference Guide

Do not bump the VR2Tx hydrophone or
expose it to extreme temperature variations.
Doing so may damage the receiver and render it
unable to detect transmitters.
Electronics inside the case must NEVER come
in contact with any water or the VR2Tx will be
damaged.
TIP: Write the date on the battery.
Close Case
Close the VR2Tx case by doing the reverse of opening it, but
first put one new desiccant pack in the bottom of the tube.
Slide the flat 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 VR2Tx.
