O-rings and lubricant are included in the MP TROLL 9000 Mainte-

moist sponge in the bottom of the Cal Cup to provide a moist environ-
ment for those sensors that require it.
TWIST-LOCK CONNECTORS
Keep the pins on all connectors free of dirt and moisture by using the
soft protective dustcap when cable is not attached.
