connected internally to ensure shield
continuity.
CAUTION
Do not ground either shield at the
network extender enclosure. Insulate the
shields to prevent shorting to the device
housing or to any other conductor.
4. Check ALL wiring to ensure that proper
connections have been made.
5. Inspect the junction box O-ring to be sure
that it is in good condition.

NOTE
The recommended lubricant is a silicone
free grease, available from Det-Tronics.
