An optional caption changer is available for installing and removing panels from the ground. Each
caption panel is punched with keyholes. Screw heads on the crossbar of the caption changer fit into
the keyholes. The caption changer pole consists of three sections, with a ring tightener to adjust for
length. Loosen the ring to extend the pole to the desired length; tighten the ring for pole use.

CAUTION

§ The aluminum caption changer can conduct electricity. Do not use it

within 20 feet of power lines.


§ Be careful when using the caption changer in high or gusting winds.

Wind may catch the panel and unhook it from the changer. The
surface area of the caption panel could also act as a sail, making it
difficult to maintain a grip on the pole. Hold the pole tightly and be
careful to maintain your balance when using the caption changer in
windy situations.
