Environmental Characteristics
The FASTRACK Supreme Plug & Play is compliant with the following operating class. To ensure the proper
operation of the FASTRACK Supreme, the temperature of the environment must be within a specific range
as described in the table below.
Table 30: Ranges of temperature
Conditions
Temperature range
Operating / Class A
-20 °C to +55°C
Operating / Class B
-30 °C to +85°C

Function Status Classification:
Class A:
The FASTRACK Supreme remains fully functional, meeting GSM performance criteria in accordance with
ETSI requirements, across the specified temperature range.
Class B:
The FASTRACK Supreme remains fully functional, across the specified temperature range. Some GSM
parameters may occasionally deviate from the ETSI/PTCRB specified requirements and this deviation does
not affect the ability of the FASTRACK Supreme to connect to the cellular network and function fully, as it
does within the Class A range.
