Location: Select a convenient 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 exten-
sion kit (86LM) for best results. See Remote Antenna
Mounting for proper installation.
Receiver Mounting: Mount Backplate to desired surface
using M3 hardware (not supplied). Hardware used will
depend on mounting application. (Refer to figure 1 for
Receiver mounting hole locations). Wire electrical connec-
tions 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.

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 per-
mit children to operate, or play with remote control transmitters.
• Activate gate of door ONLY when it can be seen clearly, is proper-
ly 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.
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
(See figure 2). Contact LiftMaster customer service to
