SECTION 2 GENERAL DESCRIPTIONS 2.1 Multi-band : CMD-J16 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). While the 900-MHz band has 124 channels (extended version: 175), the 1800-MHz band with its 375 channels provides a three-times higher capacity.

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). There are also reduced BTS power levels due to microcell applications, which means instead of the 40W (Power Class 4) in the GSM system DCS 1800 needs only 20W (Power Class 1). Pr

2.5 Battery Charging There is no charging circuitry in the battery pack. The CMD-J5/J16 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. The battery symbol is used to indicate the charging, and to indicate when the battery is fully charged. This is done usi
