INSTALLATION STEP 10

Install the Lights

• Press the release tabs on each side of lens. Gently
rotate lens back and downward until the lens hinge is
in the fully open position. Do not remove the lens.
• Install a 40 watt maximum light bulb in each socket.
Light bulb size should be E27, standard neck only. The
lights will turn ON and remain lit for approximately 2-
1/2 minutes when power is connected.
Then the lights will turn OFF.
NOTE: Lights do not turn on in battery mode.
• Reverse the procedure to close the lens.
• Use E27 standard 40 watt bulbs or 28 watt Energy
Saving Halogen Bulbs for replacement.
INSTALLATION STEP 11
Attach the Emergency Release Rope
and Handle
• 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 hole in
the release arm of the outer trolley.
• Adjust rope length so the handle is 1.8m above the
floor. Ensure that the rope and handle clear the tops of
all vehicles to avoid entanglement. Secure with an
overhand knot.
NOTE: If it is necessary to cut the rope, heat seal the
cut end to prevent unraveling.
• To release the trolley, pull down on the red handle. Do
not use the handle to open or close the door.
To prevent possible OVERHEATING of the endpanel or light
socket:
• DO NOT use short neck or specialty light bulbs.
To prevent damage to the opener:
• DO NOT use bulbs larger than 40W.
• ONLY use E27 size bulbs.
• DO NOT USE CFL (Compact Fluorescent Lamps) or Reflective
Lamps as they may cause damage to the lens cover. If unsure
check the Chamberlain web page for details.
Release Tab
To prevent possible SERIOUS INJURY or DEATH from a falling
garage door:
• If possible, use emergency release handle to disengage trolley
ONLY when garage door is CLOSED. Weak or broken springs or
unbalanced door could result in an open door falling rapidly
and/or unexpectedly.
• NEVER use emergency release handle unless garage doorway
is clear of persons and obstructions.
• NEVER use handle to pull door open or closed.
