Linear LCO75 - 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 operator or gate if it contains a Linear MegaCode™ receiver). Additional single and multi-button remote
controls can be purchased. An unlimited number of remote controls can be used with this operator. The short
wire on the back of the operator serves as an antenna for
the remote controls. Do not cut off the short wire or the
remote controls will not operate well.
To Add a Remote Control
1 Press the opener’s LEARN button. The red LEARN
light will glow. The red light will stay on for about 15
seconds. A remote must be added while the red
LEARN light is still on.
2 Send a signal from a remote. The red LEARN light and
the opener’s lights will fl ash once indicating that the
opener has accepted the remote.
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 LEARN light will
blink three times signaling that all of the remotes
in the opener’s memory were erased. The red
LEARN 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 short 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 qualifi ed garage door
professional adjust or repair the door.
4 To reconnect the opener, fl ip the release lever up.
Raise the door manually until the opener reconnects.
5 Perform the Safety Beam Test (Section 4).
6 Perform the Safety Reversal System Test as described
in Steps 4-6 in Section 6.
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 entire Door Force Safety System Test
(Section 6).
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 fl at 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 fl at 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 fl at 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.
