damage from electrostatic discharge, must be available.
The area must be equipped as follows:
> All working surfaces must have a dissipative bench mat, safe for use with live equipment,
connected via 1.2Mi2 resistor to a common ground point.
> A quick release skin contact device with a flexible cord, which has a built in safety resistor of
between 5.2MQ and 1.2Mi2 shall be used. The flexible cord must be attached to a
dissipative earth point.
> All containers and storage must be of the conductive type.

GENERAL DESCRIPTIONS
2.1 Multi-band :
CMD-CD18 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 weil as in DCS 1800; In addition it supports the extra functionality required for multi-band
mobile stations: lnter-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-CD18 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 the phone.
When the mobile is switched on the RTC is powered via the CPU.
When the phone is powered down, the RTC is powered from the main battery via it’s own low quiescent current
regulator.
When the main battery is low or removed, a back-up battery keeps the clock alive.
After the main battery has reached a voltage level of 3.5V the RTC keeps the time for 10 days.
After the main battery is removed the RTC keeps the time for 10 min.
2.3 Vibra Functionality
The vibrator is a 1.3V device with a vibrating frequency fixed at 120Hz (±20%) and located in the handset.
A general port pin of the CPU controls the switch mode of the vibration motor. It is powered directly from the
battery by an interface control unit. If the mobile is in the phase of switching on or off the vibrator is off at ail 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: The charging is stopped when Battery Voltage (Vbat) reaches (4.24V- 4.3V). The charging resumes
when Vbat falls below (4.1 IV - 4.23V).
Under voltage: When the cell voltage drops below (1.3V - 1.7V) the cell is disconnected for discharging.
Charging is still possible.
2.5 Battery Capacity:
Standard Battery
Extended Battery
The phone can be charged even during making phone calls.
However, the shortest charging time will be reached when the phone is switched off.
As the charging circuit is integrated in the battery pack, the phone cannot be powered up by the charger without the
battery pack being attached.

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.
The insertion and removal of the charger (Cigar Lighter Charger, Desktop-Charger, AC-Charger) is detected via
polling. To reduce the power consumption the polling can take up to 5 sec.
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 power to the headset
(min.2.7V and min. 10 mA) or 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.
Due to the fact that the ID of the accessory is detected first, the ACC power is not current limited (protected).
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-CD5HFK” and
Head-set “QN-2HS” have an output 280mVrms into lOkii.
Audio OUT: >
The single ended output delivers 265mV into a 32Q load.
2.7 RF Antenna connector / antenna switch
To connect an external antenna for accessory use, the CMD-CD18 contains a stable RF connector with an
integrated mechanical switch. This connector is placed on the PWB. 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.

The CMD-CD18 supports the following languages:

DISASSEMBLY
IMPORTANT NOTE :
The IMEI Sticker mounted on the main board (visible from the battery compartment) should not be removed at all.
The IMEI number is the electronic identification of the hardware, and it is stored electronically.
There should be no discrepancy between the number on the sticker and the number within the set logic allowed.
Remove the battery and the 4
screws in the battery compartment.
Note that the SIM card is also
located in this area
Insert the hook release jig (p/n 3-043-180-01) in the gap
between upper and lower case. Then gently slide the jig in
the direction of the white arrow. This is to release the claws
between the upper and lower case (as indicated by the
black arrows).
Important: Do not insert the hook release jig too deep
into the gap, that might resuit in damaging the PWB
while sliding the jig.

6.4 Display contrast adjustment
1. The hardware set-up for this adjustment is the same as for the software update.
2. Once the hardware connection is made, the CMD-CD18 must be powered on with the battery pack.
3. The display contrast adjustment software is DOS-based, the program name is LCDCONT.EXE.
4. When activating this program (either from within Windows or from the DOS prompt), by default COM port 1 is
selected as the interface between PC and the external connector of the CMD-CD5.
For other COM port selection, go to DOS prompt and enter the following parameter; LCDCONT.EXE -p<port>.
(where <port> is the number of the COM port you want to activate)
For example: to select COM port 2, the correct command to activate the program is: LCDCONT.EXE -p2.
5. When the program is correctly set and activated, the following sequence will appear on the PC;
Waiting for mobile (this message will appear for a few seconds only)
LCD contrast: X (X is a numeric value between 0 and 15)
6. The LCD contrast is adjustable by keying the ( T ) and ( i ) arrows while observing the CMD-CD18 display.
7. Once the best contrast setting is adjusted, just exit from the program and leave the DOS prompt. The adjusted
value will be automatically written into the CMD-CD18 memory.

DIAGRAMS
7.1 Radio Frequency (RF) Block Diagram
Rx
The GMSK modulated 900 MHz / 1800 MHz signal received by the antenna is downconverted into the baseband
via an intermediate frequency of 282 MHz. In the transmit direction the digitally GMSK-modulated baseband signal
is modulated to the transmit frequency in the 900 MHz / 1800 MHz bands by means of a modulation loop and the
dual power VCO.
The radio part mainly consists of the RF Synthesizer, Receiver (RX), Transmitter (TX), power amplifiers,
diplexer/switch, antenna connector with integrated switch and antenna.
