O-ring Inspection
O-rings located in the end-cap of the VR2C case are crucial to the watertight seal of the receiver. Each time
an O-ring is disturbed, for any reason, it
must
be checked before the unit is sealed again. Something as
simple as a stray hair could be the difference between a successful study and a damaged receiver.
Just as the O-rings are vital to a good seal, so are the O-ring
surfaces. These surfaces hold the O-ring in position and must
also be clean and damage free or the VR2C case could flood
with water.
Pinch the O-ring together as
shown and then pull the
exposed section out of the
groove.
STEP 2
Each time an O-ring is
disturbed, for any reason, it
must be checked
before
the unit is sealed again.
Improper care of the O-rings and their
mating surfaces can result in water leaking
into the receiver casing, destroying the
electronics.
Do not use a sharp object
near O-ring surfaces.
The
surface could be damaged.
Identify the Receiver Locking Ring
Retaining O-ring, identified by the
arrow in the photo here.
STEP 1
Slide the locking screw
collar off the lower housing.
STEP 4
Remove the O-ring from the
groove and set it aside to be
used again later.
STEP 3
Slide the Receiver
Locking Ring back onto
the lower housing.
STEP 6
Inspect the two O-rings to make sure they
have not been damaged and that they are
properly greased (a
light
coat of O-ring
grease
– too much can cause them to pop
out). Clean
any debris
from the
locking screw
collar.
STEP 5
Continued…
This is not
a sealing
O-ring
–
do not
apply
grease.
