Children's smart watches can not only track positioning, but also make phone calls, by many parents, children sought after. Many parents worry that smart watch radiation will not hurt children? January 5, Nanjing Consumer Association released a comparison of children's smart watches sample quality test results. Modern Express reporter noted that from the test results, we are quite concerned about the radiation, down there is no big problem, but there are differences in positioning accuracy, in addition to part of the watch volume can not be adjusted, may have an impact on children's hearing.
Test results
Most of the electromagnetic radiation standards, some can not adjust the volume
The test collected a total of 20 batches of samples, of which physical stores, e-commerce platform were purchased 10 batches; 200 yuan less than 6 batches, 200-500 yuan 11 batches, 500 yuan more than 3 batches basically covering all the children on the market Variety of smart watches. Focus on detecting electromagnetic radiation, audio performance and satellite positioning accuracy of the three effects.
The results show that the current market smart watch for children, the human body's electromagnetic radiation in line with the SAR limits, but also to the EU SAR safety value. This reporter has learned that 20 batches of samples, in addition to a child's watch because of its software settings can not be connected with the analog base station to establish a test state, the other batches of the test results are better, did not exceed the domestic mobile phone product head limit (2W / kg) and EU standard limb wear (4W / kg), of which a child with the highest SAR value of 0.963 W / kg.
Audio performance. From the test results, only two batches exceeded the YD / T 1538-2014 "digital mobile audio performance technical requirements and test methods," the requirements of some children's watches do not have the volume control function of the call, there is loud loudness The problem that can not be regulated is that there is a risk of hearing impairment when children use the smart phone communication function especially for infants. In response, Xu Ming, secretary general of Nanjing Consumer Association, warned that the purchase of children's smart watches, you want to buy a call with volume control function of the brand, otherwise it will have an impact on children's hearing.
Children's smart phone positioning accuracy is also the focus of consumers. Satellite positioning accuracy of the project actually tested 17 batches of children's smart watches with GPS positioning capabilities. Untested three batches of samples, including "Sailor" "smart" two products with LBS positioning function, not within the scope of the test, it is not tested. There is also a "Pu Nile" children's smart watches did not detect the accuracy of satellite positioning, but its manual is clearly marked "positioning function", suspected of false propaganda.
From the test results, children's watch more than 500 yuan mobile phone positioning accuracy is better, 200-500 yuan children's watch mobile phone satellite positioning accuracy concentrated in the 5-10m, 200 yuan below the children's watch mobile phone only a 6m positioning accuracy , The rest are in the 10m to 14m range. These values basically meet the national standards, but there are some errors.
Xu Ming said that parents should pay attention to children when positioning the function of children's watches, GPS positioning should pay attention to whether positioning, GPS positioning accuracy is better than LBS positioning, try to buy a higher price and have a certain brand awareness products , So you can accurately grasp the child's whereabouts.
Consumers Association reminded: choose brand products
Keep the invoice for the protection of rights
Most parents give their children to buy smart watches for children is to obtain a sense of security, keep abreast of the whereabouts of children. So a watch can really bring their children safe?
Xu Ming said that at present domestic children's smart watch manufacturers are mainly concentrated in Shenzhen, Dongguan and Shanghai, Jiangsu less manufacturing enterprises. As emerging electronic products, OEM processing is not uncommon, "In the process of contact with the product nominal manufacturer, found that some manufacturers are not engaged in the electronics manufacturing industry, but only trading companies, which will lead consumers in the product use In the process of consulting, after-sales maintenance can not be guaranteed. "
At present, the country has no uniform norms for smart wearable devices such as children's phone watches, and the quality of such products is also uneven. Therefore, parents must polish their eyes when buying a telephone watch for their children.
Xu Ming reminds consumers, try to choose a reputable store or a large e-commerce platform to buy a certain brand of children's smart watches, pay attention to product packaging or manual is marked with the product standard number, and issued a formal invoice to ensure that Manufacturers to provide instructions and warranty card, in order to safeguard their legitimate rights and interests.
