Aligning The Safety Sensors For Multiple Doors - Ryobi GD125 Operator's Manual

 To align the safety sensors: loosen, but do not remove,
the fasteners securing the sensors in place and adjust the
position of the sensors until the lens on the transmitter
and receiver are directly facing one another.
 After the sensors have been aligned, retighten fasteners.
 When the sensor lenses are in the correct position,
the invisible light beam emitted by the transmitter will
be captured by the receiver and the LEDs will shine
continuously.
NOTE: If an object crosses the path of the beam, an open
garage door will not close and a closing garage door
should stop and reverse to the fully open position.

INSTALLATION

Aligning the safety sensors for multiple doors:

When multiple garage door openers are installed, extra care
must be taken to prevent misalignment and crossed signals
between each set of sensors.
 Where possible, install transmitting safety sensors on an
adjacent surface facing away from each other and toward
the recievers.
 Connect the garage door opener to an AC power supply.
NOTE: Make sure the power supply is normal household
voltage, 120 volts, AC only, 60 Hz.
 Align each set of sensors as described earlier.
