requirements apply only to the S-PCN MES element of the terminal operating in the MSS frequency bands
given in table 1;
• the MES is capable in operating in all or part of the frequency bands shown in table 1.

requirements apply only to the S-PCN MES element of the terminal operating in the MSS frequency bands
given in table 1;
• the MES is capable in operating in all or part of the frequency bands shown in table 1.

• -10 °C to +55 °C;
taken from IEC publications 60068-2-1 [7] and 60068-2-2 [8].
4.1.3 Voltage
The nominal, lower and the higher extreme voltages shall be defined for the intended use of the MES and provided with
the EUT documentation.
The MES shall fulfil all the requirements in the full voltage range between the extreme voltages.
4.2 Conformance requirements
4.2.1 Unwanted emissions outside the band 1 610 MHz to 1 626,5 MHz
and the band 1 626,5 MHz to 1 628,5 MHz (carrier-on)
