Using your Broil King Grill Light & Timer - 60938 is easy. First, make sure you have 3 AAA batteries (not included) and insert them into the battery compartment. Then, use the adjustable clamp - on design to attach the light and timer to your grill or a patio umbrella pole. You can adjust the brightness of the LED light according to your needs. Set the timer up to 10 minutes and wait for the audible alarm when your food is ready. When it comes to maintenance, keep the light and timer dry. Since it's weatherproof, it can handle some outdoor elements, but don't submerge it in water. If it gets dirty, use a soft, damp cloth to clean it. When not in use, store it in a cool, dry place. Always replace the batteries when they run out to ensure continuous performance.
