Use these checklists to help you prepare
your VR4-UWM for deployment, successfully
deploy the receiver, and gather the data
when you return to the deployment location.
Do not bump the VR4-UWM
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 VR4-UWM will be
damaged.

Equipment
Initialize VR4-UWM before deploying.
Use
the magnet and the VUE software (Bluetooth
communication) and start recording to remove the
receiver from Suspend mode.
Do not open the case
except to change battery.
This receiver was sealed and pressure tested prior to
shipping.
Never deploy
a VR4-UWM
beyond 500 meters
depth.
Do not deploy VR4-UWM receivers with the
same
modem address within 5 km of each other
. Doing
so could disable modem communications with the
surface acoustic modem.
Do not allow the VR4-UWM to be
dropped or struck
against other objects.
Do not mix different metals
, especially in contact
with each other. This will promote galvanic corrosion
and cause rapid failure of the hardware.
Initializing the VR4-UWM will erase the receiver’s
memory
. Retrieve all detection logs before the VR4-
UWM is initialized.
Important
F
Make sure
latest VUE version
is installed on PC, including the latest
manuals
.
F
Start a study
using VUE software and Bluetooth communication (exit Suspend mode).
F
Perform an
in-air test
(see manual) using
Bluetooth
communication.
F
Perform an
in-air test
(see manual) using
Benthos
acoustic modem communication.
Preparation - On Land
Never cover the Status Light/
