The wrist alarm is not a voltage detector, and it is prohibited to be used as a voltage detector. Because high-voltage operation is very dangerous, operators must undergo rigorous training and obtain corresponding high-voltage operation certifications before using the instrument for on-site testing. 2. When using, please wear the alarm on the bare skin of your wrist and keep the watch case close to the skin. Make the triangular symbol on the surface of the alarm point point toward 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 decrease. 5. If the alarm is hung on the sleeve of work clothes or rubber gloves, the sensitivity will not decrease. 6. 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. 7. If the siren is hit or hit b
