Introduction
1.1
System Overview
The VR2 is a submersible, acoustic receiver capable of identifying VEMCO coded transmitters. The receiver
operates on a factory set frequency and can decode various combinations of sensor and pingers. The VR2
receiver consists of electronics and hydrophone housed in a cylindrical corrosion resistant case. Its features
include a Smart LED (light emitting diode), two megabytes of data storage, a resume study feature, and a
replaceable battery (a single Lithium cell).
The VR2 records the pinger identification code number, date and time of each detection. This information is
stored in the receiver’s memory for later retrieval using a VR PC interface and a PC computer running VUE
software.
NOTE:
As of January 2007, the VR2PC software has been replaced with the VEMCO User
Environment (VUE) software. VUE software is available at
WARNING
The black VR2 pressure case and seal have a maximum static depth
rating of
500 meters
(730 psi).
Physical shocks to the receiver, such as bumping into a solid object, when it is
at any depth can result in a considerably higher pressure on the casing than
just the depth pressure and water may enter the VR2 case. If the O-rings or
their mating surfaces are dirty or damaged, then water may also enter the
receiver case. If you are suspicious that water has entered the receiver, then
follow the suggestions in section 8.2.2 for troubleshooting a pressurized case.
WARNING
If the VR2 is not used in the manner specified by the
manufacturer protection may be impaired.
