VEMCO – VR100 Manual 28 May 2018 40
4.4.5 Performing Acoustic Release (VR2AR only)
The VR2AR receiver has the capability to release from its mooring and, with the proper floatation attached,
rise to the surface. Deploying a VR2AR is explained in the VR2AR user manual. Below are the instructions
for sending the release command from the VR100-200 receiver to the VR2AR.
STEP 1
Select “Acoustic Release” (#3) from
the main transponding menu to begin
the release process.
STEP 2
NOTE: A VR2AR with firmware 1.2.5 and up does not require this
arming step. Just proceed to the Activate step described next.
Select “Arm” (#2) to let the VR2AR
know that you are about to send a
command to release the mooring lug.
This acts as a safety feature to
prevent a release command from
accidentally being sent to a receiver.
Press the MENU button to return
to the Acoustic Release menu.
STEP 3
Select Activate to send the release command.
After reading the confirmation screen, select “Activate” (right selection key). The status is reported as
“Opening” until the motor in the VR2AR has completed its task, at which time the status changes to “Open.”
With the proper amount of buoyancy attached to the VR2AR, it should be rising to the surface.
STEP 4
Select “Status” (#1) and wait until the VR2AR’s status is shown (see below).
“Opening” indicates that the mooring lug is currently being expelled from the
VR2AR; “Open” means the lug is expelled and the VR2AR has been released.
Watch the depth value decrease, indicating that the VR2AR is rising. The
status also reports the “hRange” or the horizontal range to the VR2AR. If the
depth is listed at (or close to) “0m” then you know the receiver is at the surface
and the hRange indicates the distance from the boat.
The amount of battery life remaining in the AR release battery is also shown.
STEP 5
Use the MENU button to return to the main transponding screen.
