ANNEX- Spot Check of Output Power
Company Name: TCL Communication Ltd. Product Name: MOVETIME FAMILY WATCH Model Name: MT40A
Differences between models MT40A(SC9820E chip) is changed to MT40A(SL8521E chip), the two chips only have different screen printing information, other no difference, and the two chips themselves have no change, also does not affect RF performance.

Note: Spot check test data included for the variants based on worst-case results reported in the

original.

From the above data, it can be concluded that the conducted output power of the variant is less

than or near to the original. And the variant conducted test data can refer to the original report

(I19N01990).

This condition applies to the reports I21N04009.
