Function/description: [To identify equipment which is suitable for the use in the subtropics.For new applications, the use of this symbol is deprecated and IEC 60417-6332 shall be used.]
Additional information:
* Equipment is suited for use in the subtropics in accordance with ISO 5155 if the required storage temperature is maintained at an ambient temperature between +18º C and +38º C
* [ISO 5155 was withdrawn and replaced by ISO 15502 and this was replaced by IEC 62552 and this in turn has been replaced by the IEC 62552 series. None of these standards nor IEC 60335-2-24 use symbols IEC 60417-5785 (2002-10-07) or IEC 60417-5786 (2002-10-07). They use a letter to indicate the climate class.]
