To prevent possible SERIOUS INJURY or DEATH from electrocution:
• Be sure power is not connected BEFORE installing the receiver.
To prevent possible SERIOUS INJURY or DEATH from a moving
gate or garage door:
• ALWAYS keep remote controls out of reach of children. NEVER
permit children to operate, or play with remote control transmitters.
• Activate gate or door ONLY when it can be seen clearly, is properly
adjusted, and there are no obstructions to door travel.
• ALWAYS keep gate or garage door in sight until completely closed.
NEVER permit anyone to cross path of moving gate or door.
MOUNTING INSTRUCTIONS FOR STAR250
Location: Select a convienent location near your device to be
controlled by the STAR250. For best performance, the STAR250
should be mounted in “Line-Of-Sight” with your intended
transmitting location. Avoid mounting the STAR250 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 Backplate to desired surface using #6
hardware (Not provided). Hardware used will depend on 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 supplied antenna onto the
STAR250 antenna connector by screwing the connector
clockwise. Slide the seal boot down to meet the O-Ring, covering
the antenna hardware.
Figure 2
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.
