Vemco VR2Tx - O-ring Care and Maintenance

VEMCO - VR2Tx Manual 15 March 2019 33
5.2 O-ring Care
O-rings located in the end-cap of the VR2Tx 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 VR2Tx case could flood with water.
5.2.1 Remove O-rings
The O-rings must be removed from their grooves to allow the
O-rings and the grooves to be inspected and cleaned. Do not use
a sharp object, which may damage the groove surface, when
removing the O-rings. Always wear protective gloves when
handling O-ring grease!
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.
Use a lint-free cloth to grip
two points on the O-ring
with your thumb and finger,
approximately 5 cm apart.
It’s best to start with the
O-ring farthest from the
case threads.
STEP 1
Pull your thumb and finger
towards each other while
maintaining your grip on
the O-ring. This requires
pressure against the
O-ring and should produce
a loop of exposed O-ring.
STEP 2
Grab the exposed O-ring and
pull it away from the end cap,
so it moves along the body of
the receiver.
STEP 3
Repeat Steps 1 -3 for the other
O-ring.
STEP 4
Clean any O-ring grease on the
plastic casing.
