 Technical specifications

■ easy to use.
■ small size, light weight (the total weight including the battery is about 50g), easy to carry.
■ low power consumption, two AAA batteries can last for 10 hours.
■ when the battery voltage is too low and may affect normal use, there will be a low voltage warning indicator in the visual window.
■ when there is no signal, the product will automatically shut down after 8 seconds.
