ZM8620_V2
and the extreme working temperature range. Under the normal working temperature range, the testing
result of RF complies with the requirements of 3GPP specifications, and its function is normal. Under
the extreme temperature range, the RF index basically complies with the 3GPP specifications, and the
quality of data communication is affected to a certain extent, but its normal function is not affected.
ZM8620_V2 has passed the EMC test. Table 6–2 is the requirement for the testing environment, and
Table 6–3 lists out the instruments and devices that might be used during the test.
