The wrist alarm is not a voltage detector, and it is prohibited to be used as a voltage detector._x000D_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._x000D_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._x000D_3. This alarm only provides safety assistance measures, please do not overestimate the safety guarantee after wearing this alarm._x000D_4. Near grounded metal structures (such as transformer), the working distance of the alarm will not decrease._x000D_5. If the alarm is hung on the sleeve of work clothes or rubber gloves, the sensitivity will not decrease._x000D_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._x000D_7. 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._x000D_8. Please read the manual carefully after purchase. 1Providing safe and practical high?voltage alarm devices for real?time operators to ensure their safety. 2The high voltage alarm has ultra-high sensitivity, which can detect low voltage of 40V. 3Using non?contact sensing technology, accurate alarm, energy saving and durable, waiting time up to 12 months. 4Direction induction voltage power supply, automatic trigger detection mode, sound and light alarm mode, to ensure the safety of workers close to electricity. 5The high voltage detector is light in weight, reducing the burden for the operator and saving effort. 1 x High Voltage Alarm (Battery Not Included) 1 x Manual 1 x Button Piece
