Vemco VR2Tx Quick Manual

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.
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.
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.
VR2Tx Quick Guide
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.
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 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
Do not bump the VR2Tx
hydrophone or expose it to
extreme temperature variations.
