SECTION 2 GENERAL DESCRIPTIONS 2.1 Multi-band : CMD-J6/J26 support E-GSM 900 and DCS 1800 multi-band functionality. For the use in Europe and in other countries worldwide, ETSI has specified GSM standards into two frequency bands. That is the 900-MHz and 1800-MHz band and is usually referred to as GSM900 and GSM1800 (formerly DCS1800).
2.2 Radio Frequency Power Levels: Between the DCS 1800 and both GSM Systems are differences regarding the power level. DCS 1800 basically needs lower power levels. If the performance of a MS for GSM system was certified of 2W (Power Class 4), then in the DCS-1800 system it is only 1W (Power Class 1).
2.5 Battery Charging There is no charging circuitry in the battery pack. The CMD-J6/J26 has complete charger function internally. The telephone can be charged only with the battery connected the phone. This situation can be sub-divided into two situations: the phone is on or off. It can be charged with the AC Adapter, Travel Charger or Cigar Lighter Charger.
