Programming Instructions
The 894LT remote can be programmed to various LiftMaster, Chamberlain, and Sears Craftsman garage door openers and gate operators. Identify the type of system you have before proceeding.
Method 1: Programming to a Garage Door Opener with a Learn Button
This method applies to most modern garage door openers (manufactured 1993-present) that feature a 'Learn' button on the motor unit.
- Locate the Learn Button: On your garage door opener motor unit, find the 'Learn' button. The color of the button or the LED next to it indicates the technology:
- Yellow Learn Button: Security+ 2.0 (manufactured 2011-present)
- Purple Learn Button: Security+ 315 MHz (manufactured 2005-2011)
- Red/Orange Learn Button: Security+ 390 MHz (manufactured 1996-2005)
- Green Learn Button: Billion Code 390 MHz (manufactured 1993-1997)
- Activate Learn Mode: Press and immediately release the 'Learn' button on your garage door opener. The learn indicator light will glow steadily for 30 seconds.
- Program the Remote: Within 30 seconds, press and hold the desired button on your 894LT remote control.
- Release Button: Release the remote button when the garage door opener lights flash or two clicks are heard. This indicates that the remote has been successfully programmed.
- Test: Press the programmed button on your remote to confirm it operates the garage door.
Method 2: Programming to a Garage Door Opener with DIP Switches (9-Trinary or 12-DIP)
This method is for older garage door openers or gate operators that use physical DIP switches for coding. The 894LT can learn these codes.
- Identify DIP Switch Settings: Open the battery cover of your existing remote control or the control panel of your garage door opener/gate operator to view the DIP switch settings. Note the position of each switch (ON, OFF, or for Trinary: +, 0, -).
- Enter Learn Mode on 894LT: Press and hold the two outside buttons (buttons 1 and 4) on the 894LT remote until the LED light turns solid.
- Select Button for Programming: Press and release the desired button on the 894LT remote that you wish to program. The LED will flash slowly.
- Transmit Existing Code: Hold your existing, working remote control approximately 1-2 inches away from the 894LT remote. Press and hold the button on your existing remote that operates the device you want to control.
- Confirm Learning: Continue holding the button on the existing remote until the LED on the 894LT remote flashes rapidly and then turns solid. This indicates the code has been learned.
- Exit Learn Mode: Press any button on the 894LT remote that was not programmed, or wait 30 seconds for the remote to exit learn mode automatically.
- Test: Press the newly programmed button on your 894LT remote to confirm it operates the garage door or gate.
If you are programming to a system with 9-Trinary DIP switches, ensure your existing remote is transmitting the correct code for the 894LT to learn accurately.
Operating Instructions
Once programmed, operating your LiftMaster 894LT remote control is straightforward:
- To Open/Close: Press the programmed button once. The garage door or gate will begin to move.
- To Stop: Press the programmed button again while the door/gate is in motion.
- To Reverse: If the door/gate is stopped mid-travel, pressing the button again will reverse its direction.
Maintenance
- Cleaning: Wipe the remote control with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Battery Life: The CR2 battery typically lasts for several years under normal use. If the remote's range decreases significantly or the LED indicator light becomes dim, it's time to replace the battery.
- Storage: Store the remote in a cool, dry place. Avoid prolonged exposure to direct sunlight or extreme temperatures.
