Vemco VR2W Quick Reference 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.
Open Case
Place VR2W 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 VR2W 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 VR2W has
previously been deployed, replace the O-rings.
The battery is connected to VR2W 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.
VR2W Receiver
Quick Reference Guide
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.
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.
Close Case
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 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
VR2W.
