Unless otherwise specified:
•
JESD22-A114 ± 1kV Human Body Model (TBC)
•
JESD22-A115 ± 200V Machine Model (TBC)

Signals
SIM connector
Adding ESD protection is highly recommended at the point where
the USIM contacts are exposed, and for any other signals that
would be subjected to ESD by the user.

1.8. Environmental and Certifications
1.8.1. Environmental Specifications
The environmental specification for both operating and storage conditions are defined in the table
below.
Table 4.
Environmental Specifications
Conditions
Range
Operating Class A
-30°C to +70°C
Operating Class B
-40°C to +85°C
Storage
-40°C to +85°C
Class A is defined as the operating temperature ranges that the device:
•
Shall exhibit normal function during and after environmental exposure.
•
Shall meet the minimum requirements of 3GPP or appropriate wireless standards.
Class B is defined as the operating temperature ranges that the device:
•
Shall remain fully functional during and after environmental exposure
•
Shall exhibit the ability to establish an SMS or DATA call (emergency call) at all times even
when one or more environmental constraint exceeds the specified tolerance.
•
Unless otherwise stated, full performance should return to normal after the excessive
constraint(s) have been removed.
