Adapt the Radio Control of REILS to the equipment and the needs of the
airport.  For one- or two-setting REIL systems, turn off the REILS at the
lower intensity and leave powered at the higher intensity.

When a runway has approach lights that are Radio Controlled and edge
lights that are not, the edge lights are left on at an intensity level selected
according to the anticipated weather conditions during the hours of night
operation.  If the runway lights are Radio Controlled and the approach lights
are not, then the approach lights may be left off or at a pre-selected
brightness.  The approach lights should never be on while the runway lights
are off.  On runways where the approach lights and runway lights are both
radio-controlled, the intensities of both systems are increased or decreased
simultaneously by the Radio Control.

When the intensity of the lighting system is automatically controlled by a
photocell or other means, the Radio Control powers the system.  The
intensity is selected automatically by the photocell.

This subsection describes the RL-854 Radio Control unit theory of
operation.

The RL-854 has three major components: the mother printed circuit board
(PCB), the Receiver PCB, and the Decoder PCB.

See Figure 2.  Power is supplied to the motherboard via terminal block TB1.
Fuse F1 protects and switch S1 switches the power to the primary power of
transformer T1.  T1 has two 120 V ac primary windings that are operated in
parallel.
