7.1.4 Closing The HR2 Case
Two steel rods
are necessary to properly open and close the case. Every shipment of new HR2
receivers includes a pair of steel rods.
Before deploying or storing a HR2 receiver, the case must be properly closed and sealed to prevent
damage to the electronics. Water, even in a small quantity, can damage the internal circuits beyond
repair. 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.
IMPORTANT
: Before closing back your receiver, check the inside for any signs of moisture/water.
Completely dry the battery tray and parts before re-assembling and deployment.
Perform a visual inspection of the O-rings and the O-ring surface inside the outer cylinder to be sure
they are clean, properly greased, undamaged, and debris free. For more information, see
VEMCO recommends the HR2 be opened and closed in a controlled environment, and
not
in the field
or on the deck of a boat.
Step 1 - Use a new desiccant pack
Place a new
desiccant pack
(if the existing one has been used in a previous
deployment) in the bottom of the outer cylinder so both ends of the pack are touching
opposite sides of the cylinder’s wall (sideways).
NOTE:
A desiccant pack has been included in the bottom of the HR2 receiver to
reduce the occurrence of condensation. One of these packs should remain in the
receiver case during storage and deployment.
We recommend that you replace the desiccant pack with
each deployment
and
with
each battery replacement cycle
.
For more information on the availability and usage of these packs, consult our
Step 2 - Slide the components together
Insert one steel rod into the hole that runs through the
diameter of the case near the
bottom end
of the HR2.
Gently slide the receiver end cap into the outer cylinder, until
the threads are in position for hand tightening.
NOTE
: The bottom end steel rod acts as a stabilizer for the
outer cylinder.
