(Original Gilbert Instructions)
INSTRUCTIONS FOR INSTALLING NO. 769
ROTARY BEACON.

No. 769 Rotary Beacon consists of a plastic lattice work tower, a special lamp and a rotating lens housing. The lamp and lens housing are packed in their own containers.
Install the Beacon as follows:
1. Clean off the insulation from the ends of the two wires.
2. Connect one of the wires to the base post on the transformer. Connect the other wire to the 15 Volt post on the transformer. When using a No. 14 Rectiformer, the two wires should be connected to the two alternating current pouts.
3. Take lamp No. 461 from its package and screw it firmly into the socket on top of the tower. Note that the top of the lamp has a small cup-like depression.
4. Unpack the rotary lens housing carefully and gently lower it over the lamp so that the steel pivot inside the housing rests in the cup on top of the lamp. Handle the housing carefully. It is very delicate.
After a minute or two the lamp will heat the air inside the housing and this warm air streaming through the vents in the top of the housing will cause it to turn slowly. If you wish you can start it off. by spinning it gently in clockwise direction.
IMPORTANT: If you wish the beacon to operate at its normal slow speed keep it out of drafts. The rotating housing is so light that a slight breeze will speed up its normal motion considerably, or stop it completely.

Addendum: There are several other factors that can effect the operation of the Beacon.
1. The Tower should be set up and be as level as possible.
2. The temperature in the room can cause the beacon to take longer to heat up.
3. The vents on the top of the beacon should be adjusted, usually they get closed down and restrict the air flow.
As stated in the original instructions, the beacon is delicate, so any adjustments must be made with care.
