Because highvoltage operation is very dangerous, operators must undergo rigorous training and obtain corresponding highvoltage operation certifications before using the instrument for onsite testing. 2: When using, please wear the alarm on the helmet, so that the triangular sign on the surface of the alarm point faces the direction of your fingertips. 3: This alarm only provides safety assistance measures, please do not overestimate the safety guarantee after wearing this alarm. 4: Near grounded metal structures (such as transformer), the working distance of the alarm will not be reduced. 5: When the alarm clock gets wet in the rain, please take out the battery and dry it naturally in a cool place. Please do not use the alarm in a humid state, this time it will greatly shorten the working distance of the alarm, even the alarm will always sound an alarm. 6: If the siren is hit or hit by a strong external force, check the appearance of the siren and press the TEST key to test to ensure that the siren functions normally. 7: Please read the manual carefully after purchase..
