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 a voice, SMS, data transmission, emergency call, etc. There is no
unrecoverable malfunction. There are also no effects on radio spectrum and no harm to radio
network. Only one or more parameters like P
out
might reduce in their value and exceed the specified
tolerances. When the temperature returns to normal operation temperature levels, 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, unregister the device, etc.) to ensure the full function of emergency call.
4. “*” means under development.
