CAUTION
Corrosive substance hazard
If the canned dry nitrogen or air is held upside down, inert gas may
be released onto the connector surface. The inert gas leaves
contamination on the connector surface that cannot be removed.
When performing this step hold the canned dry nitrogen or air
upright.
While holding the canned dry nitrogen or air, position the tip of the
nozzle extension as close as possible, but not close enough to make
physical contact, to the sleeve inside the port receptacle and make
three consecutive short blows (approximately one second each).
Repeat this step for the other port.

Using the stereo zoom scope, visually inspect the transmission
module. If required, repeat
up to two more times then go to the
next step.

CAUTION
Equipment damage
Do not perform this step on the receive (RX) port. The receive (RX)
port contains a lens for focusing a wide input. The lens is more easily
scratched than cleaned.
This step should only be performed on the transmit (TX) port if
the air blows did not work.
If required, insert a CLETOP stick into the transmit (TX) port sleeve
until vertical force can be applied to the fiber stub end surface. Rotate
the CLETOP stick five full rounds.
