Chamberlain RDO800 manual Attach the Release Handle and Cord, Operating the Manual Release

7 Attach the Release Handle and Cord

•Thread one end of the rope through the hole in the top of the red handle so “NOTICE” reads right side up as shown. Secure with an overhand knot at least 25mm from the end of the rope to prevent slipping.

•Thread the other end of the rope through the link on the emergency release cable.

•Adjust rope length so the handle is no higher than 1.8m above the floor. Secure with an overhand knot. If the door is greater than 2.5m in height the Release Cord Extension kit accessory is required.

NOTE: If it is necessary to cut the rope, heat seal the cut end with a match or lighter to prevent unraveling.
