1.3 SAR Requirements
User Operation
Do not operate your telephone when a person is within
8 inches (20 centimeters) of the antenna. A person or
object within 8 inches (20 centimeters) of the antenna
could impair call quality and may cause the phone to
operate at a higher power level than necessary and
expose that person to RF energy in excess of that
established by the FCC RF Exposure Guidelines.
IMPORTANT
The telephone must be installed in a manner that
provides a minimum separation distance of 20 cm or
more between the antenna and persons to satisfy FCC RF
exposure requirements for mobile transmitting devices.
Antenna Installation
IMPORTANT:
To comply with the FCC RF exposure limits and satisfy
the categorical exclusion requirements for mobile
transmitters, the following requirements must be met:
1. A minimum separation distance of 20 cm must be
maintained between the antenna and all persons.
2. The transmitter effective radiated power must be
less than 3.0 Watts ERP (4.9 Watts or 36.9 dBm
EIRP). This requires that the combination of antenna
gain and feed line loss does not exceed 16 dBi.

4.1 Turn On/Off the unit.
The D15 is powered from a single power supply in the range of
3.0 to 6.0 Vdc.
The unit will not power up automatically by connecting the
power and there are two ways to turn the unit On.
4.1.1 Turn On/Off the unit using the ON/OFF pin.
The On/Off pin (pin no’ 14 at the ZIF connector & pin no’ 18
at the DIN connector) is used as a toggel input to turn On and
Off the unit. Any drop to ground in this pin will change the
status.
To verify that the unit is On or Off you have to check the
DSC_EN line, If it is high the unit is On If it is low the
unit is Off.

4.1.2 Turn On the unit using the TS pin.
The main used of the TS line is for units connected to a
mobile device in witch the current consuption is not the main
consern.
The TS line is used to turn On the unit. This line can’t turn
Off the unit.
When this line is rised up it will turn On the unit.
This line is used for example to turn On the unit when power
is connected to the unit. (Like Ignition line in a car kit).
Be aware that if you keep this line high all the time the unit
will not go to Sleep mode (current save mode), So it is
recommended to turn On the unit and than drop this line.

There are two modes to use the Data port:
- SoftGSM mode. This mode is for computer aplication in witch
an application SW “SoftGSM” is use. This alowed the D15 to
work with V42.bis (data compression), transfer fax and
SMS.
- RS232 full flow control. This is the defaul setting for the
D15. In this mode we can transfer data and SMS using a full
flow control (HW flow control), Xon/Xoff or non flow
control.
There is now FAX capability in this mode.

4.2.1 Using the SoftGSM.
4.2.1.1 SoftGSM Selection
The selection of SoftGSM is done by Hardware in the user
application.
In order to switch to this mode the user need to connect
pulldown resistors of 22Kohm in the Downlink line (pin no’23
in the zif connector or pin no’22 in the 28 pin) and the
DCS_EN line (pin no’22 in the zif connector or pin no’20 in
the 28 pin).
In this mode the necessary lines are: TXD, RXD.
An example for the circuitry to add the pulldown resistor can
be seen in Pharagraph ??? EV_board design.
4.2.1.2 File / Fax / SMS transfer in SoftGSM mode.
To Transfer a file in softGsm you need to:
1. connect the RX/TX lines of the D15 a a comm port of the
computer. .(the levels should be converted to RS232 or use
a EV board or equivqlent).
2. Run the SoftGsm Application in the computer.
3. The SoftGsm program will open a phone tools application.

4.2.2 Using RS232.
4.2.2.1 RS232 Selection
The RS232 is the default setting in the D15 and no HW
selection is needed.
The RS232 can use 3 different modes of setting to the DTE
device:
HW (Hardware) flow control – all RS232 lines are used (DTR,
DSR, RTS, CTS, TXD, RXD, DCD, RI, GND).
None flow control – DTR, DSR, TXD, RXD, DCD, RI, GND are
required.
Xon / Xoff flow control – DTR, DSR, TXD, RXD, DCD, RI, GND are
required.
4.2.2.2 work with RS232 with "sleep mode"
If the D15 will have no accessories and the unit is camped the
D15 will go to a "sleep mode" (current save mode).
During this period of time the RS232 is not responding to any
command from the DTE device(Uart is not activated).In order to
make the unit to wake up when the DTE will like to communicate
with the radio the user have two options:
1. Activate the RTS During all the DTE/DCE dialog. (Internaly
the TS line will be activated). After the communication
disable the RTS in order to go back to sleep mode.
2. Activate the TS During all the DTE/DCE dialog. After the
communication disable the TS in order to go back to sleep
mode.

4.3.2 Analog Audio.
The D15 is driving out the analog audio detected by the radio.
The D15 is not including any audio drivers. The user have to
include the audio drivers in is application.
An example for audio drivers can be seen in the EV board
appendix ??.
The D15 can provide the analog audio in two ways:
- Analog audio to by drived to an Headset – Default.
- Analog audio with Echo canceller activated – for Hands free
applications.
When an Headset is used in the user application than audio
drivers for the headset are needed.
When an external Speaker and Microphone are used drivers for
them are required and activation of Echo canceller in the D15
DSP is required.
To activate the Echo canceller you need to type an AT command
in the Data port.
ATs96=1 will activate the Echo canceller.
ATS96=0 will disable the Echo canceller.
The block diagram for the required drivers are shown below,
But detailled example of drivers design you can see the

5.1 Power supply consideration.
5.1.1 Power Supply losses.
The D15 is specified to operate from 3.0V to 6.0V. In order to
be able to work in the lowest battery values it is important
to verify the losses in the power supplies lines, Flat cable
and in the user PCB.
The D15 is a GSM phone that transmits in pulses of about 0.5mS
any 4mS. The Peak current is about 1.5A.
The VCC line will drop down in the TX periods:
In order to minimize the ∆ it is recommended to use a short
Flat cable as possible and to put a 1000uF capacitor (or
maximum possible) in the D15 VCC input.
5.1.2 Current consumption in D15:
In order to design the power supply correctly you need to take
in account the current consumption of the D15 in the different

5.1.3 How / When to make the unit to wakeup.
If the D15 will have no accessories and the unit is camped the
D15 will go to a "sleep mode" (current save mode).
During this period of time the RS232 is not responding to any
command from the DTE device.In order to make the unit to wake
up when the DTE will like to communicate with the radio the
user have two options:
1. Activate the RTS During all the DTE/DCE dialog. (Internaly
the TS line will be activated). After the communication
disable the RTS in order to go back to sleep mode.
2. Activate the TS During all the DTE/DCE dialog. After the
communication disable the TS in order to go back to sleep
mode.
Note: If the RTS or TS line will be active all the time the
unit will not switch to Sleep mode and the avarage current
consumption without a call will be arround 50mA.
Timing diagrams should be added. - TBD
5.2 Audio circuits consideration.
The D15 is able to make a voice call as well as Data calls.
In voice calls the audio can be routed in a few channels:
Digital audio chanel - Audio is sent via the DSC bus.
Analog audio channel - Drived externaly to audio devices.
Analog audio channel in Hands free mode - D15 sens the
audio out with the Echo canceling ON in the DSP, External
drivers are required.
The Selection between each one of the channels can be done
according to the table XX in paragraph 4.3.2.

5.2.1 Digital audio.
In case of digital audio channel a DCS drives is in used. The
consideration that should be taken in this case is to be aware
of the present of the hook switch. The hook switch will
destinguish if the handset is In/Out of use.
There are two DSC bus accessories for audio defined for the
D15:
External Handset.
DHFA - Car Kit for Hands Free.
5.2.2 Analog Audio without Handsfree.
The D15 will drive the audio out/in in order to allowed a
voice call. In order to connect an Headset it is needed to
amplified the speaker and microphone channels.
An example for these drivers can be seen in Apendix ?? EV
board.
Other point to be taken in consideration is the Buzz noise
existing in GSM phones due to the transmission rate (217Hz).In
order to minimize this noise the D15 have a separate ground
for the analog circuits.

The main problem causing the Buzz is drops in the Ground line
because the peak current during TX mode. In order to minimize
the Buzz the following acts should be done:
- Use short Flat cable.
- Connect the analog ground from the D15 to all the analog
circuits in the customer application without connecting them
to the power supply ground.
- all the capacitors to ground in the audio circuits should be
connected to the analog ground.
- Any reference voltage that may be used should have the
external capacitor connected to the analog ground.
5.2.3 Analog Audio with Handsfree
The audio In/Out from the D15 for analog Handsfree are the
same as for non Handsfree.All the consideration from Paragraph
5.2.2 are applicable for this mode too.
The additional consideration in this case is to switch the D15
DSP to Echo cancelling mode.
In oreder to switch to handsfree mode use the RS232 port by
sending a switch command.
ATS96=1 Echo canceller is activate. (Handsfree)
ATS96=0 Echo canceller is disabled. (headset - Default)

5.3 Data port considerations.
5.3.1 Data levels.
The D15 data lines are operating in 0 to 5V logic. All the
In/Out signals are bufferd by an MC74VHCT244 buffer.
DTR, DSR, RTS, CTS, DCD lines are "1" (active) in 0V and "0"
(inactive) in 5V.
The signal treshoulds are:
Vih 2.0V min.
Vil 0.8V max.
Voh 4.4V min. @ 50uA or 3.8V min. @ 8mA.
Vol 0.1 max. @ 50uA or 0.44V @ 8mA.
5.3.2 Select the data mode:
The D15 can support two different modes of operation:
SoftGsm - For PC applications.
RS232 full flow control - General applications.
The RS232 is the default mode and no action is needed to
switch to this mode.
The SoftGsm require hardware connection to two lines.
Down link pin should be connected via 22KOhm to ground.
DSC_EN pin should be connected via 22KOhm to ground.

5.4 SIM lines consideration.
The SIM card can be used in 3 different ways: Internaly in the
D15, Externaly by connecting a socket in the customer
application and remotly via the DCS bus.
In case of externaly connection the customer concern should be
for Full Type Approval that may require submittion for testing
in case that the SIM lines will be longer than 10cm.
This Paragraph should be completed.
5.5 ESD consideration - TBD
5.6 Antenna - To take from D10 manual.
5.7 Software - TBD
5.8 Mechanical - TBD
