5.1
Main Battery Replacement
Replacing the main battery (D or DD-cell) in the VR2AR requires four basic steps:
1.
Opening the case (section 5.1.1)
2.
Removing the battery (section 5.1.2)
3.
Inserting the battery (section 5.1.3)
4.
Closing the case (section 5.1.4)
5.1.1
Open the VR2AR Case
A steel rod is necessary to properly open and close the VR2AR case. Every shipment of new VR2AR
receivers includes a steel rod.
WARNING
It is vitally important that the electronics inside the receiver case
do not come in contact
with any water
or the receiver will be damaged. For this reason, VEMCO recommends the
VR2AR be opened in a controlled environment and
not
in the field or on the deck of a boat.
Make sure there is
absolutely no water
on or near the VR2AR case.
Water, even in a small quantity, can damage the VR2AR internal circuits
beyond repair. If the VR2AR is attached to a wet rope,
remove the receiver from the rope before opening the case.
STEP 1
This also means the electronics cannot be exposed to a
sudden change
in temperature and humidity
that will cause condensation to develop on
the electronics and destroy the receiver.
Place the VR2AR on a clean, flat surface so the hydrophone is
hanging over the edge but the float attachment bracket is still on
the surface. DO NOT let the receiver fall off the surface.
TIP: A non-slip surface, such as a rubber mat, helps keep the
VR2AR in place while opening it.
