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.
