The ASCENT-AR is shipped closed. The case only needs to be opened to power the unit. Because the
ASCENT-AR is often shipped with the battery installed but not connected, the first task is usually to open the
case and either connect or install the battery. The only other time the case needs to be opened is when
replacing the battery or preparing the unit for long-term storage. Connecting the battery is explained in
Section 2, along with opening and closing the release case. Replacing the battery is explained in Section 5.1.

WARNING
The ASCENT-AR pressure case and seal have a maximum static depth rating
of
500 meters
(730 psi). Physical shocks to the release, such as bumping
into a solid object, when it is at any depth can result in a considerably higher
pressure on the casing than just the depth pressure and water may enter the
ASCENT-AR case. If the O-rings or their mating surfaces are dirty or
damaged, then water may also enter the release case. If you are suspicious
that water has entered the release, then follow the suggestions in section 8.2.2
for troubleshooting a pressurized case.
