OPERATION OF YOUR OPENER

Your opener can be activated by any of the following
devices:
• Opener Control Panel: UP & DOWN buttons
• Remote Control Transmitter: hold the button down
until the door starts to move.
• The Outside keyswitch or keyless
entry system (if you have installed any of these
accessories).
• The Transmitter or Wireless Wall
Control (E128M)
Hold the push button down until the door starts to move.
When the opener is activated:
• If open, the door will close. If closed, the door will open.
• If closing, the door will stop.
• If opening, the door will stop (allowing space for entry
and exit of pets and for fresh air).
• If the door has been stopped in a partially open or
closed position, it will reverse direction.
Obstruction behaviour:
• If an obstruction is encountered while closing, the door
will reverse.
• If an obstruction is encountered while opening, the door
will reverse and stop.
• The optional Protector System™ uses an invisible beam
which, when broken by an obstruction, causes a closing
door to open and prevents an open door from closing. It
is STRONGLY RECOMMENDED for homeowners with
young children.
Door should be fully closed if possible.
Weak or broken springs could allow an
open door to fall rapidly. Property damage
or serious personal injury could result.
Opening the door manually:
The door can be opened manually by pulling the release
cord down firmly.
To re-engage the door, pull the release cord down firmly.
The opener light will turn on:
• when opener is initially plugged in;
• when the power is briefly interrupted;
• when the opener is activated.
• when IR Beams are triggered with the door in the
Open position.
(the light turns off automatically after 2-1/2 minutes.)
SPECIAL NOTE: Chamberlain strongly recommends that the
TM
Protector System be installed on all garage door openers.

CARE OF YOUR OPENER

When properly installed, your opener will operate with
minimal maintenance. The opener does not require
additional lubrication.
Limit and Force Settings: These settings must be checked
and properly set when the opener is installed. Weather
conditions may cause some minor changes in the door
operation, requiring some re-adjustments, particularly
during the first year of operation. Refer to limit and force
setting in, section 13.
Follow the instructions carefully and repeat the safety
reverse test after any adjustment.
Transmitter: Additional transmitters can be purchased at
any time. Refer to Accessories. Any new transmitters must
be programmed into the opener.
Transmitter battery: If transmission range decreases,
replace the battery.
