GENERAL DESCRIPTIONS

2.1 Multi-band :

CMD-MZ5 support E-GSM 900 and DCS 1800 multi-band functionality.

Because the usage of multi-band depends on network capabilities, the phone is able to operate as a single band mobile in GSM 900 as well as in DCS 1800; In addition, 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 PLMN’s operating in GSM 900 and DCS 1800 bands.

The CMD-MZ5 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.

2.2 Real Time Clock (RTC)

The real time clock is integrated into phone.

When the mobile is switched on the RTC is powered via the CPP. When the phone is powered down, the RTC is powered from the main battery via its own low quiescent current regulator. When the main battery is low or removed, a back-up battery keeps the clock alive.

2.3 Vibra Alert Functionality

The vibrator is a 1.3V device.

A general port pin of the SC1 controls the switch mode of the vibration motor. It is powered through a regulator by an interface control unit. If the mobile is in the phase of switching on or off the vibrator is off at all times.

2.4 Battery Safety

The battery pack contains a safety circuitry. 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 when Vbat falls below 4.06V - 4.15V.

Under voltage Charging is still possible.

: The charging is stopped when Battery Voltage (Vbat) reaches 4.24V- 4.3V. The charging resumes

: When the cell voltage drops below 2.5V - 2.7V the cell is disconnected for discharging.

2.5 Battery Charging

Standard Battery 620mAh typical Li-ion 1-476-508-11

The phone can be charged even during making phone calls. However, the shortest charging time will be reached when the phone is switched off.

The Connector Comprises the following pins:

Detection

The detection of accessory is done by the charge pin and the detect pin.

Any accessory with an active charge will wake up the phone, indicating the battery icon but cannot be operated.

The insertion and removal of the charger (Cigar Lighter Charger, Desktop-Charger, AC-Charger) is detected by the charge voltage.

The insertion and removal of other accessory is detected via an Interrupt. This detection is only possible when the phone is powered up.

ID:

The ID pin indicates what kind of accessory is connected.

ACC power:

ACC-power has different functionality with different accessories. ACC-power supplies will be used as a signaling pin for the Hands Free Kit.

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.

RX and TX:

This is the communication interface to the PCMCIA card “QN-2PCM” or the PC-link cable “QN-2EC”.

Audio In and Audio Out

These pins build the audio interface to the Head-Set and the Hands Free Kit.

Audio IN:

To limit the noise which is coupled on the Mic-line, the Mic amplifier in the Hands Free Kit “QN-MZ5HFK”.

Audio OUT:

The single ended output delivers 350mV into a 10kW load.

2.7 RF Antenna connector / antenna switch

To connect an external antenna for accessory use, the CMD-MZ5 contains a stable RF connector with an integrated mechanical switch. This connector is placed on the I/O connector. The integrated mechanical switch switches between the helix antenna and the external RF antenna connection. The switching criterion is mechanical pressure from the RF accessory connector.

2.8 Languages

The CMD-MZ5 supports the following languages:

• Dutch • German • Spanish

• English • Italian

• French • Portuguese

2.9 Memory stick

# You can record sound data onto the memory stick at the bitrate of 132kbps, 105kbps and 66kbps by Optical

input or Analog input.

# Receiving an incoming call is stopped during recording sound (to keep good sound quality). # You can playback sound (data) recording onto the memory stick. # The Play Settings function allows you to select how to play back such as Bass, AVLS, and Repeat (Shuffle). # Selecting the next track, the previous track, going forward, backward and stop are available. # When you receive an incoming call during playback, playback is stopped automatically and the Ringer is heard

from the headphones. An incoming call is received with pressing the answering / ending call button on the remote.

# To end, keep the answering / ending call button on the remote pressed. # Playback sound can be stopped by pressing the answer / ending call button on the remote during playback. # Also, to start playback, press the answer / ending call button on the remote. # When WAP is being used, you can not playback sound recorded onto the memory stick.
