5.1
Main Battery Replacement
Replacing the main battery (D or DD-cell) in the ASCENT-AR 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)
NOTE:
The process is the same for the AR or AR2.
5.1.1
Open the ASCENT-AR Case
A steel rod is necessary to properly open and close the ASCENT-AR case. Every shipment of new
ASCENT-AR includes a steel rod.
WARNING
It is vitally important that the electronics inside the release case
do not come in contact
with any water
or the release will be damaged. For this reason, VEMCO recommends the
ASCENT-AR
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
ASCENT-AR
case.
Water, even in a small quantity, can damage the
ASCENT-AR
internal
circuits beyond repair. If the
ASCENT-AR
is attached to a wet rope,
remove the release 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 release.
Place the
ASCENT-AR
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 release fall off the surface.
TIP
: A non-slip surface, such as a rubber mat, helps keep the
ASCENT-AR
in place while opening it.
