4.About Update of Test Report and Test

If the product meets application scope of TRP and TRS, i.e the handheld voice device wider than 56 mm and narrower than 72 mm, then TPR & TRS should be added under the new standard.
If the product is out of application scope, for example, it is not handheld, not support voice mode and the size is too large, then no need to add TRP & TRS under the new standard.
In any case, to update Standard Version, it is necessary to supplement the stray test according to the requirements of the new standard.
