(3) When using multiple sets of the AJ65BT-RPI-10A/10B in line,
provide shields between the sets. Not doing so can cause a
malfunction due to interference.
(4) When using multiple sets of the AJ65BT-RPI-10A/10B in parallel,
place the A and B modules alternatively and keep a distance of at
least 1m (3.28ft.). Not placing them alternately can cause a
malfunction due to interference.
Referring to the figure showing the relation between the optical
communication distance and the distance from the other system,
adjust the optical axis to remove the influence of interference light.
(Refer to Section 4.6.3.)

*1 A value obtained when the optical axis of each system is adjusted to nearly
the center of the area in which the operation indicator LED, R3 turns on.
*2 A value obtained when the optical axis of the system is slanted toward the
other system.
