⚫  Storage temperature range: -40 °C to +95 °C 
Firmware Upgrade 
⚫  USB 2.0 interface   
⚫  DFOTA 
RoHS 
All hardware components are fully compliant with EU RoHS directive 
1. 
1)
 Within operation temperature range, the module is 3GPP compliant, and emergency call can be dialed out 
with a maximum power and data rate.   
2. 
2)
 Within extended temperature range, the module remains fully functional and retains the ability to establish 
and maintain functions such as voice, SMS, data transmission and emergency call, without any unrecoverable 
malfunction. Radio spectrum and radio network will not be influenced, while one or more specifications, such 
as P
out
, may undergo a reduction in value, exceeding the specified tolerances of 3GPP. When the temperature 
returns to the normal operating temperature level, the module will meet 3GPP specifications again.   
3. 
3)
 Within eCall temperature range, the emergency call function must be functional until the module is broken. 
When  the ambient  temperature is between  75  °C  and  90  °C  and  the  module temperature has reached the 
threshold value, the module will trigger protective measures (such as reduce power, decrease throughput and 
unregister the device) to ensure the full function of emergency call.
