Linear LDCO801 - User Manual

2 Remote Controls
This opener is supplied with a three-button remote control (the second and third buttons can be used to control an
additional opener or gate if it contains a Linear MegaCode™ receiver). Additional single and multi-button remote
controls can be purchased. The short wire on the back of the opener serves as an antenna for the remote controls.
Do not cut off the wire or the remote controls will not
operate well.
To Add or Remove a Remote Control
1 Press the opener’s LEARN button. The opener’s light
and red light will flash once and turn on for about
15 seconds. A remote must be added or removed
while the red light is still on.
2 Send a signal from a remote. The opener’s light and
the red light will flash once if a remote was added, or
the opener’s light and the red light will flash four times
if a remote was removed.
3 Repeat Steps 1 & 2 for any additional remote controls.
To Remove all Remote Controls
1 Press and hold the opener’s LEARN button for ten
seconds or more.
2 Release the LEARN button. The red light and
opener’s light will blink three times signaling that
all of the remotes in the opener’s memory were
erased. The red light will turn off, then turn on for 15
seconds. A remote control can be entered during this
time using Step 2 above.
Testing
1 Before testing the remote control, straighten out the
opener’s antenna wire so it points up.
2 Stand clear of the door, press the remote control’s
button and verify that the opener starts.
Replacing a Remote Control’s Batteries
When the red light on the remote glows dimly, or fails
to light at all when the remote is activated, the batteries
need replacing.
1 Open the remote’s case and remove the circuit board.
2 Replace old batteries with two Type 2032 batteries.
3 Re-assemble the remote.
3 Garage Door Opener Maintenance
Weather conditions may affect the door operation which
could require some re-setting of the opener’s adjustments.
Doors may swell and become heavier during wet periods,
door hinges and rollers might bind during cold periods. To
insure safe operation of the door, perform the following
tests, including any additional test steps described.
Every Month
1 With the door closed, pull the red release handle to
disconnect the opener from the door.
2 From outside the garage, slowly open the door
manually all the way, and then close it all the way.
Notice if there is any binding, sticking or rubbing. The
door should move smoothly in both directions.
3 Raise the garage door about halfway up. Carefully
release the door and see if the door balances. It
should stay in place. Close the door.
�
NOTE: If the garage door is unbalanced or the
door travel isn’t smooth, have a qualified garage door
professional adjust or repair the door.
4 To reconnect the opener, flip the release lever up and
run the opener.
5 Perform the Safety Beam Test (Section 4).
6 Perform the Safety Reversal System Test as described
in Section 8.
After Servicing the Opener
1 Perform the Safety Beam Test (Section 4).
2 Perform the Open and Close Limit Adjustments
(Section 5).
3 Perform the Safety Reversal System Test (Section 8).
Every 6 Months
Check the belt or chain tension.
• For belt-drive rails, examine the length of the tension
spring in the traveler. It should be about 1” long.
• For chain-drive rails, examine the spacing between
the turnbuckle and the rail. The turnbuckle should be
slightly above the rail.
�
NOTE: Too much or too little chain tension will cause
excessive sprocket noise.
Chain Adjustment
If necessary, use the following steps to adjust the chain.
1 Hold the turnbuckle with a flat blade screwdriver and
loosen the two locknuts with a 7/16” end wrench.
2 Twist the turnbuckle to adjust the chain tension. Adjust
the chain until the turnbuckle is sightly above the rail.
3 Hold the turnbuckle with a flat blade screwdriver and
tighten the two locknuts with a 7/16” end wrench.
Belt Adjustment
The tension spring in the traveler keeps the belt taut. The
factory setting for the tension spring length is .9” long. If
the tension spring is longer than 1”, adjust the belt.
1 Hold the traveler so the adjustment wheel is visible
through the large slot.
2 Use a flat blade screwdriver to turn the adjustment
wheel to compress the tension spring until its length
is between .9” and 1” long.
Every Year
Check the door hardware for lubrication needs. Lubricate
door hinges, rollers and bearings according to door
manufacturer’s recommended procedures.

IMPORTANT SAFETY NOTES
Please read the instructions carefully! This garage door opener is designed to provide safe and reliable service if installed

1 With the door in view, press the wall station’s UP/
DOWN ARROW button, the button assigned to the
opener on the remote control, or enter a valid access
code and press START/STOP on a remote keypad.
2 When the opener is activated, the opener’s light will
turn on and the door will begin to open.
3 The door will open until the open limit is reached. If
an obstacle is encountered (opener’s light flashes four
times) while the door is opening, the door will stop.
4 The opener’s light will stay on for about five minutes
after the door stops.
Closing the Door

6 Test door opener monthly. The garage door MUST reverse on contact with a 1-1/2 inch object (or a 2x4
board laid flat at the center of the door) on the floor. If adjusting either the force or the limit of travel,
re-test the door opener. Failure to adjust the opener properly may cause severe injury or death.
