Using the Bosch BLAZE Pro GLM165 - 40 is a breeze. First, insert the 2 AAA batteries that come with it. Then, you can turn it on and start measuring right away. Point the laser at the target, and the backlit display will show you the measurement in real - time. If you need to calculate the area or volume, just use the appropriate function buttons. You can also add or subtract measurements as needed. When it comes to storage, you can save up to 10 measurements for later use. As for the hand strap, it's there to make it easier for you to carry the tool around. Just loop it around your wrist. Now, for the precautions. Keep the tool away from water and dust as much as possible, even though it's IP54 rated. Don't drop it, as it might affect the accuracy. And when it comes to maintenance, clean the laser lens gently with a soft, dry cloth. If the batteries run out, replace them with new AAA batteries. That's all you need to know to get the most out of your Bosch BLAZE Pro GLM165 - 40 laser distance measure.
