NOTES
1)
1.
Within the operating temperature range, the module meets 3GPP specifications.
2)
2.
Within the extended temperature range, the module keeps the ability to establish and maintain
functions such as SMS*, data transmission, etc., without any unrecoverable malfunction. Radio
spectrum and radio network will not be influenced, while one or more specifications, such as P
may undergo a reduction in value, exceeding the specified tolerances of 3GPP. When the
temperature returns to the operating temperature range, the module will meet 3GPP specifications
again.
