OWNER'S MANUAL Model 33LM Multi-Function Remote Control Transmitter The 33LM Multi-Function Remote Control Transmitter can be used with a 423LM 3-channel receiver and a 3-button door control to operate a commercial door opener in open, close, and stop mode (as explained on side 1). It can also be used with other transmitters to operate a garage door opener, in which case the code switches in all transmitters must be set to match (see side 2). To comply with FCC/IC rules, adjustment or modification of receiver and/or transmitter is prohibited, except for changing the code setting and replacing the battery. THERE ARE NO OTHER USER SERVICEABLE PARTS. To use the transmitter with a 3-channel receiver and 3-button door control to operate a commercial door opener: WARNING Install the control station and receiver where the door is visible, but away from the door and its hardware. When a receiver is used to activate a commercial door opener, a reversing edge MUST be installed on the bottom of the door. Failure to install a reversing edge under these circumstances may result in serious injury or death to persons trapped beneath the door. Use a screwdriver to pry open the receiver cover (see illustration). The slide switch is factory set to the N.C. position (otherwise the opener will not operate). Verify this setting . • Select a remote control push button to STOP the opener. (RED is recommended.) • Press and hold the selected remote push button. • Then press and release the "smart" button labeled "A" on the receiver. The adjacent indicator light will FLASH. Release the remote push button. Repeat the procedure above with the yellow remote push button and receiver "smart" button "B" to program the CLOSE operation; and again with the green remote push button and receiver "smart" button "C" to program the OPEN function of the opener. Return the front cover to the receiver. (For this application, code switch settings need not be changed.)
