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. Not only as a result of this large range of channels but also due to the low transmission power and the transmission distance, GSM1800 supports a higher quantity of RF-channels. The Dual band technology enables a network operator with spectrum at both 900MHz and 1800MHz to support the seamless use of dual band handsets across both frequencies. By supporting seamless handovers between 900MHz and 1800MHz, Dual band networks can provide major benefits in terms of capacity enhancement and revenue optimisation through the introduction of new services. The CMD-J6/J26 is a phase II, GSM 900 class 4, DCS 1800 class 1 mobile phone. The nominal maximum output power for GSM 900 is 2W, for DCS 1800 1W. It supports the extra functionality required for multi-band mobile stations: Inter-band/seamless hand-over, channel assignment, cell selection and re-selection, all between both bands within a Public Land Mobile Network. The manual and automatic PLMN selection in both bands is given. The user does not need any special action to use the multi-band functionality of the phone. Users are able to manually roam between PLMNs operating in GSM 900 and DCS 1800 bands. E-GSM With the further development of the GSM standard, an additional range of frequencies has been made available to the Global system for mobile communications. For each of the two duplex frequency ranges, one for the forward direction and one for the reverse direction, additional 10 MHz have been added to the bottom end of the bands, extending the frequency range to 50 further channels. The mobile station transmits in the 880- to 915 MHz range, and the base station transmits in the 925- to 960 MHz range. A duplex spacing of 45 MHz is used, the base station always transmits on the high side of the duplex frequency pair. The numbering for these additional channels is from 974 to 1023. This is done to avoid assigning one channel number twice within the same standard. Compared to the primary GSM system, Channel number 0 is used in the extended GSM system, since it does not make sense to reserve it at a guard band within the E-GSM bands. Now, the lowest channel, number 974 (880.0 MHz), serves as the guard band between GSM and other services on lower frequencies. DCS 1800 DCS-1800 uses the frequency ranges of 1710 to 1785 MHz in the uplink direction, and 1805 to 1880 MHz in the downlink direction. From these figures it follows that the duplex spacing is 95 MHz with 374 channels with bandwidths of 200 kHz each. The channels are numbered from 512 to 885 in order to distinguish them from the channels in the primary and extended GSM frequency bands. 4 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). Preferences GSM 900 E-GSM DCS 1800 Frequency band uplink: downlink: MHz 890 - 915 935 - 960 MHz 880 - 915 925 - 960 MHz 1710 -1785 1805 - 1880 Radio Channels 124 174 374 max. BS-Power 40 W (46 dBm) 20W (43 dBm) max. MS-Power 2 W (33 dBm) 1W (30 dBm) 2.3 Speech Codec The CMD-J6/J26 supports the following speech codecs. • • • Full Rate (FR) Codec Half Rate (HR) Codec Enhanced Full Rate (EFR) Codec The speech codec forms the human voice into a digital signal, which is sent in the GSM network. The GSM system currently has three different speech codec standards. At first, the Full Rate (FR) Codec was introduced. With new requirements concerning speech quality and availability of radio channel resources two further standards were introduced, the Half Rate (HR) Codec and the Enhanced Full Rate (EFR) Codec. The Half Rate (HR) Codec requires only half the channel capacity of a Full Rate (FR) Channel. The Enhanced Full Rate (EFR) Codec requires the same radio channel resources as a Full Rate (FR) Codec but offers Fixed Line quality with superior vocal clarity. 2.4 Languages The CMD-J6 supports the following languages: • • • • • • • Bulgarian Croatian Czech Danish Dutch English Finnish • • • • • • • French German Greek Hungarian Italian Norwegian Polish • • • • • • • Portugese Romanian Russian Slovakian Spanish Swedish Turkish The CMD-J26 supports the following languages: Taiwan • English Hong Kong • English • Chinese Simplified • Chinese Traditional (for Taiwan) • Chinese Simplified • Chinese Traditional 5 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. The battery symbol is used to indicate the charging, and to indicate when the battery is fully charged. This is done using the following sequence of icons: The uncharged segments of the battery are moving in a right to left manner until the charging stops. The sequences for each charging level is repeated until the battery is charged to that level. When the charging sequence is finished the flashing of the battery level sign stops. The phone shows the full-battery icon. 2.6 Battery Safety The battery pack contains a single Li-ion cell, a safety circuitry and, in addition, a microprocessor unit which manages RTC information by reading out the binary counter value in the microprocessor. The charging circuitry and the safety circuitry together guarantee a double fail-safe battery pack. This means that each component can be either short or open and still all the safety requirements will not be violated. The safety concept protects against: Over voltage: The charging is stopped when Battery Voltage (Vbat) reaches 4.25V- 4.3V. The charging resumes when Vbat falls below (4.025V - 4.125V). Under voltage: When the cell voltage drops below 2.242V 2.358V the cell is disconnected for discharging. Charging is still possible. Current fuse: Finally, if all protection functions are out of order due to abnormal condition, the current fuse protects the device from explosion and fire with melting. The fuse melts 10A during 1 second. 2.7 Battery Capacity Standard Battery 640mAh typical Li-ion QN-J6BPS Extended Battery 920mAh typical Li-ion QN-J6BPE The phone can be charged even during making phone calls. However, the shortest charging time will be reached when the phone is switched off. 6 2.8 Accessory interface The table explains what kind of pins the phone supplies to the different accessories.

Audio OUT: The single ended output delivers 0.8Vpp into a 1kΩ load. These two signals are referred to as AGND. RS232 Interface 5-pin interface: RX, TX, RTS(RFR), CTS and Gen I/O(DTR or DCD): This is the communication interface to the Data cable QN-3RS/USB. Pin 3 is connected to a general IO pin on the baseband digital chip. The functionality can be assigned on an accessory by accessory basis to be input, output or interrupt. Charge The Charge pin represents the positive contact for the charging funtionality. GND The Ground pin represents the digital interface and charger return current. ID This pin shows the presence of an accessory and is also an analog ID for the accessory. Accessories which provide charger functionality only do not support this pin and their presence is detected with a valid charger voltage. Power Out Power-out has a different functionality with different accessories. In the car-kit environment the ext. Vbat indicates that a phone call is accepted/in progress. This information is used by the car-kit to power up the audio section of the car-kit, mute the car stereo and keep the car-kit powered up even when the ignition is switched off. Due to the fact that the ID of the accessory is detected first, the ACC power is not current limited (protected). 7 SECTION 3 OPERATING INSTRUCTIONS 3.1 The Basic Features of the CMD-J6/J26 • Parts and Controls This section provides a brief guide to the operation and facilities available on the CMD-J6/J26.

It is the main contributor for the dualband functionality for E-GSM 900 and DCS 1800. Receiver The receiver consists of two separated RF paths for GSM and DCS 1800 each. On the transmission line between the antenna switch of the RF part and the antenna there is the RF connector including a mechanical switch to connect an external antenna for accessory use. The integrated mechanical switch switches between the helix antenna and the external RF antenna connection. As long as a plug is connected the antenna is deactivated and all RF signals go across the connector. The GMSK (Gaussian-filtered minimum shift keying) modulated 900 MHz / 1800 MHz signal received by the antenna is filtered, gained and downconverted into the baseband via an intermediate frequency of 440 MHz. The 440 MHz filter is followed by a tuneable amplifier and IQ demodulator. Behind the demodulator there are additional base band amplifiers and low pass filters. The In Phase (I) and Quadrature (Q) signal outputs are balanced each. A 13 MHz voltage-controlled-temperature-compensated crystal oscillator (VCTCXO) generates the clock frequency for the PLL and baseband part. Transmitter In the transmit direction the digitally GMSK-modulated baseband signal is upconverted to the transmit frequency in the 900 MHz / 1800 MHz band via an intermediate frequency of 195 MHz (GSM) / 325 MHz (DCS 1800) by means of an IQ modulator and the subsequenting sum loop. All RF and IQ signals are balanced signals in order to suppress crosstalk effects. According to GSM recommendations transmitter and receiver are never active at the same time.
