Exit Suspend Mode
For a VR4-UWM that was just shipped, or one that was in storage, the first task after communication is to
remove it from Suspend mode. Suspend mode is used to reduce power consumption and prolong the life of
the battery. While in Suspend mode, the receiver is not listening for tags or storing data – it’s using as little
power as possible while waiting to receive the command to begin recording again. The VR4-UWM can
communicate with VUE using Bluetooth communication when the receiver is in Suspend mode but it will not
communicate using the acoustic modem. So, if a VR4-UWM is deployed in Suspend mode then it will sit on
the bottom, unable to collect data and unable to communicate with the surface. This is why it’s so vital that
the receiver be taken out of Suspend mode.
To remove a VR4-UWM from Suspend mode, simply
start a Study. The basics of how to do this are
explained here but more information on setting up a
Study is found in section 3.2.1.
Always bring VR4-UWM out of
Suspend mode before deploying
receiver.
The receiver won’t
communicate via the acoustic
modem when it is in Suspend mode.
Click the red and blue “Start Recording” button found in the receiver
tab’s ribbon. This button is not available if communication between
receiver and VUE software is not present.
STEP 1
Review the PC clock time listed in the dialogue box
that opens. The receiver will be set to UTC time
based on the current time of the PC so the PC time
and the UTC offset must be correct. If the time or
UTC offset are not correct, then click “Cancel” and
make the necessary corrections before returning to
start the study. If the time and UTC offset are correct,
then click the “OK” button to continue.
STEP 2
Select
ERASE
to begin a study.
STEP 3
CAUTION:
Verify the receiver you
are
communicating with is the
intended unit
, particularly before
initializing and erasing receiver
memory files, or data could be lost.
Communication can occur with any VR4-UWM
or VR2W with
Bluetooth®
wireless technology
activated within a 10 meter range (typical range
in air).
