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.

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

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.

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

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 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.

Main Battery

TIP:

 Write the date on the battery.

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.

Close Case

Electronics inside the case must 

NEVER come 

in contact with any water

 or the VR2Tx will be 

damaged.
