Step 1 WARNING: Power to the Beacon must be removed prior to servicing.

Step 2 The Dome Assembly (D264-2005) is secured to the Beacon base by three

latches. One of the latches has a locking screw that must be removed before it

can be undone. Undo all three latches located on the base of the Beacon

assembly. The Dome assembly lanyard is secured to the Beacon Base support

bolt. The Dome may be carefully lifted off the top of the Beacon by gently

pulling outward on the lanyard hole tab and letting air enter. Once released, the

Dome can be removed and set aside of the tower until ready for re-installation.

Step 3 Undo the (3) knobs holding the LED module (D264-1016) to the Base

assembly. The knobs are captive and will remain in the Base Plate.

Step 4 Carefully lift the LED module enough to allow access to the cable connecting it

to the power supply unit (fixed to the base). Carefully pull the inline connector

between the LED module and power supply apart to separate the two

assemblies.

Step 5 Replace the LED module using the alignment pins as a guide, make sure the

LED cable is connected to the power supply, before retightening the knobs to

secure the LED assembly to the base.

Step 6 Apply power to the Beacon and verify it lights correctly.

Step 7 Refit the dome, CAUTION:

When reinstalling the Dome it is important to

hold it level and securely by the lower rim. With even pressure gently lower

the dome over the o-ring seal until the bottom lip of the dome is seated on

the (3) cast latch pads, ensure that the lanyard tab is approximately

centered between two of the latch clamp pads. Clamp all latches and refit

the locking screw.
