Mounting Instructions for STAR450
Location
Select a convenient location near your device to be controlled by the STAR450. For best performance, the STAR450 should be mounted in “Line-Of-Sight” with your intended transmitting location. Avoid mounting the STAR450 in or on metallic enclosures. If this is unavoidable, we recommend installing the antenna extension kit (86LM) for best results. See Remote Antenna Mounting for proper installation.
Receiver Mounting
Mount back plate to desired surface using #6 hardware (not provided). Hardware used will depend on mounting application (refer to Figure 1 for receiver mounting hole locations). Wire electrical connections to unit. Snap unit to back plate.
Direct Antenna Mounting
Install the provided antenna onto the STAR450 antenna connector by screwing the connector clockwise. Slide the seal boot down to meet the O-ring, covering the antenna hardware.
Remote Antenna Mounting
Use the optional 86LM antenna extension kit to mount the remote antenna as high and far from metal as possible for best radio range (Figure 2). Contact LiftMaster customer service at: 1-800-528-2806 to order the model 86LM.
