8.2 Environment temperature range
The recommended operating temperature range of NL668-LA series module.is -30℃~+75℃. When
module operating at limited temperature range, some RF indexes may exceed standard, so module
application terminal should consider temperature control measurement. The module application terminal
is recommended storage in certain temperature conditions. Modules out of the temperature range may
not operate or may be damaged.
