PRECAUTION

Important

Please read the following cautions, notes and

warnings before progressing through this manual or

undertaking any repair action.

Remember: SAFETY FIRST!

CAUTION:

AC Power Cord:

Care must be taken not to damage the AC power cord as fire or electric shock may
result.

Battery Pack:

Only use the specified batteries and chargers with this equipment.
Do not short the battery terminals together.
Keep the battery pack away from fire and sources of ignition.
Remember to recharge the battery pack after each use.

Before Powering up the Equipment:

• Only switch on the telephone’s power once the test or installation set-up is

complete.

• Switching on at the wrong time may result in electric shock or damage to system

components.

• Always ensure that the power is switched off before making connections /

disconnection’s.

• It is important to check that the correct DC voltage is applied to the equipment to

prevent electrical damage.

Component Polarity:

Always check the polarity of connections and components before soldering.
Particular attention must be paid to IC.s, diodes, transistors, capacitors and any
other semiconductor device that is polarity dependent.

KP320 SERVICE MANUAL V1.2

6

Electrostatic Damage (ESD):

Semiconductor devices are easily damaged by electrostatic discharge. Many of the
procedures detailed in this manual involve disassembly of the equipment and
therefore handling of the printed circuit boards.
To protect these devices from ESD a wrist strap connected to ground must be worn.
In addition to this the work surface must be covered with an anti-electrostatic mat,
which should also be grounded.
If printed circuit boards are to be stored without being re-assembled into their
equipment, then they must be kept in an anti-electrostatic bag.

Grounding:

Each piece of test equipment should be electrically grounded. A third (grounding)
pin is provided as a safety feature. Ensure that the electrical outlet also contains
this feature.

Cosmetic Protection during Repair Work:

Always ensure that the working surface is kept clean and free from abrasive
materials.
The LCD is very susceptible to scratches and damage. It should be covered with
clear adhesive vinyl while the equipment is disassembled.

Storage of Faulty Components:

Any components that are replaced due to failure should be kept safely in an anti­electrostatic container. NEC’s Quality or Research & Development Departments
may require them to make quality and reliability investigations.

No Fault Found Equipment:

In some cases the reported symptom may not be apparent. You may subject the
equipment to a controlled amount of stress, vibration and temperature variation to
see if the fault occurs.
Care should be taken not to apply excessive stress or vibration or extreme
temperature variations as further faults may develop.

KP320 SERVICE MANUAL V1.2

7

Soldering and Disordering :

The solder used is only Pb-free.
Fast, accurate and high quality soldering is required to minimize the risk of heat
damage to the electronic components.
It is necessary to adjust the temperature of soldering tip to 330 degrees or less.
The soldering tip should not be in contact with components or PCB tracks for longer
than 4 seconds (average). This time depends on temperature conditions of parts.

Heat the pad on the PCB and the lead, quickly apply solder, remove heat and cool.

After soldering is complete, ensure that all solder joints are of good quality - no dry
joints, solder bridges, cracks or excess solder.
The majority of chip components are machine mounted using solder paste.
Removal of the solder is not sufficient for chip component removal. Each solder
point must be heated simultaneously and quickly (to prevent component and PCB
damage). When the solder has melted, remove the component with tweezers.

Short Circuits:

Care must be taken to avoid short circuits. Soldering, solder dust, screws, metal
clippings, metal wrist watches etc. can cause short circuits on PCBs which may
result in component damage.

Test Equipment Calibration:

Your test equipment should be calibrated before use. Frequent calibration is
essential to ensure high quality and reliable repairs.

Cleaning:

Before cleaning ensure that the telephone is switched off and disconnected from the
power source. Cleaning should be done using a soft dry cloth. If the equipment is
heavily soiled a soft cloth soaked in a mild synthetic detergent diluted in water may
be used.
Never use benzene or any other chemicals to clean the equipment.

RF Shielding:

It is advisable to carry out detailed measurements and repair (in particular RX) in a
shielded area to minimize RF interference.

AC Adapter and Battery Charger:

The AC adapter and battery chargers are for indoor use only. Ensure that the
devices are not exposed to rain or moisture

KP320 SERVICE MANUAL V1.2

8

Electrical Safety:

Electrical equipment is hazardous if misused. Any repairs must be carried out with
care and only by authorized personnel.
Ensure all power sources are switched off and power cords removed before
undertaking any repairs.

Hazardous Waste:

The battery pack, if incorrectly disposed of, is an environmental hazard. It must be
disposed of in accordance with the regulations of the country concerned.
Never dispose of the battery pack in fire or water.

Confidentiality:

The circuitry within this equipment contains several components that are regarded
as company confidential. Only use NEC specified parts as replacements.

RF Injury:

To avoid RF injury, direct exposure to radio frequency energy should be avoided. In
particular, exposed parts of your body (especially the eyes and face) should not
come into contact with the antenna while the equipment is transmitting.

Storage Conditions:

It is recommended that the following storage conditions should be avoided to
prevent damage to the equipment: ­ Dusty.
Humid.
Near to magnetic equipment

In direct sunlight

Ventilation:

Repair areas should be well ventilated and fume extraction systems should be
installed where necessary. Potential hazardous substances are solder fumes, flux,
alcohol etc.

PCB Handling:

It is recommend that cotton gloves are worn during repair work. This is to protect
your hands from chemical contamination and to protect the PCBs from fingerprints
and humidity
.

SIM Card:

• Do not bend.

• Clean by using a soft dry cloth.

AUDIO Parts:

• Be careful for alien substance/oils and fats, etc. not to adhere to the terminal contact part of MIC, the

receiver, the speaker.

• Be careful to handle AUDIO parts with electrostatics measures at the worker/in the working place.

• Be careful not to spend a stress on the MIC side part to the utmost.

• Be careful not to pressurize the coil joint (protection Bond part) of the receiver and speaker because

they are easy of broken.

• Be careful for alien substance to approach to sound hole part of the speaker.

• Be careful sufficiently so as not to blow air with the process into the receiver, speaker/MIC sound hole.

It causes sounds being small by the diaphragm transformation or vibration.

The KG195 HHP works closely with the network and the standby and talk times achieved depend
upon this. In particular the location of the HHP within the network, the type of SIM, reception of
area messages, the use of AMR, Full Rate speech, Half Rate speech or Enhanced Full Rate
speech and other factors will affect both standby and talk times.

5-2-9 BATTERY CHARGING

Battery management, which controls charge and discharge of the battery is
the most important function for safety. 7338 SW performs charging algorithm. To
regulator the power PMOS for set the charging current.

KP320 CHARGING CIRCUIT AND ALGORITHM

charging Circuit and Algorithm

7610 Charging circuit:

The schematic below shows the external charging components used in the Arima
7610 project. All ports are directly connected to the corresponding pins of PMU IC
(6318). VCHG is the V charger supply rail coming directly from the wall-plug constant
voltage charger via the system connector, and VBAT is the Battery Voltage rail,
connected directly to the battery pack terminal connector. The system uses a solid
ground plane, and both the Battery Pack terminal and the wall-plug charger return

paths are connected directly to ground.

KP320 SERVICE MANUAL V1.2
61

Charger Sub-system

The MT6305 battery charger can be used
with Li-ion and NiMH batteries. BATUSE
pin can set MT6305 to fit the battery type.
When BATUSE is set low, Li-ion battery is
used. When BATUSE is set high, then
NiMH battery is used. MT6305 charges
the battery in three phases: pre-charging,
constant current mode charging, and
constant voltage mode charging. Figure 2
shows the flow chart of charger behavior.
The circuitry of MT6305 combines with a
PMOS transistor, diode and current-sense
resistor externally to form a simple and
low cost linear charger shown in Figure 3.
MT6305 is available pulsed top-off
charging algorithm by the CHRCNTL pin
control from baseband chipset.

Charge Detection

The MT6305 charger block has a
detection circuit that determinates if an
adapter has been applied to the CHRIN
pin. If the adapter voltage exceeds the
battery voltage by 3.75%, the CHRDET
output will go high. If the adapter is then
removed and the voltage at the CHRIN
pin drops to only 2.5% above the VBAT
pin, CHRDET goes low.

Pre-Charging mode

When the battery voltage is below the
UVLO threshold, the charge current is in
the pre-charging mode. There are two
steps in this mode. While the battery
voltage is deeply discharged below 2V, a
10mA trickle current of MT6305 charges
the battery internally. When the battery
voltage exceeds 2V, the pre-charge
current is enabled, which allows 10mV
(typically) across the external current
sense resistor. This pre-charge current
can be calculated:

KP320 SERVICE MANUAL V1.2
62

Constant Current Charging Mode

Once the battery voltage has exceeded the UVLO threshold the charger will switch to the constant
current charging mode. The MT6305 allows 160mV (typically) across the external current sense resistor.
This constant current can be calculated.

If the voltage of Li-ion battery is below 4.2V (5.1V for NiMH battery), the battery will be in the

constant current charging mode.

Constant Voltage Charging Mode

This mode is only applied to Li-ion battery charging. If the battery has reached the final charge
voltage, a constant voltage is applied to the battery and keeps it at 4.2V. The charge termination is
determined by the baseband chip internally, which will pull the CHRCNTL low to stop the charger. Once
the battery voltage exceeds 4.3V of Li-ion battery (5.1V of NiMH battery), a hardware over voltage
protection (OV) should be activated and turn off the charger block of MT6305.

Pulsed Charging Algorithm

MT6305 is available to pulsed top-off charging algorithm by the CHRCNTL pin. The control signal is
from baseband chipset to limit the charging duty cycle. This charging algorithm combines the efficiency
of switch-mode chargers with the simplicity and low cost of linear chargers.

Battery Voltage Monitor

As the Table 2 shown, the relations of battery voltage and charger control signals are listed. When
Vbat < 3.2V, an UVLO signal is active low. When Vbat >= 4.3, an OV signal is active and terminates
charging. The disconnection of battery could be detected by BATDET pin. BATDET is pulled high
internally when battery disconnected and terminates charging immediately.

5-2-10. REAL-TIME CLOCK (RTC)

RTC is the feature to count “second”.

MTK6229’s clock generation on 32.768kHz is made by OSC(X401 in 7610),
connecting to OSC32K_IN/ OSC32K_OUT and supply the clock to 6318.

The real-time clock (RTC) is driven by a 32.768 kHz clock from a crystal oscillator.
The input clock is divided by 32.768 to generate a clock with a 1 second period. In
addition, it can generate interrupts at a programmed time. The following are basic
function of RTC:

-Time information (seconds/minutes/hours) coded in BCD

-Calendar information (Day/Month/Year/Day of the week) directly in BCD code up to
year 2099.

-Alarm function with interrupts generation bases on a periodical
(second/minute/hour/day) or a precise time event in the century (second accuracy).

-30s time range correction

-32khz oscillator frequency gauging.
The RTC module of 7610 is supplied by 3V Backup Battery made by Sanyo.
The target of running time of the backup battery (fully charged) is longer than two
hours after the main battery is removed.

5-2-11. EXTERNAL INTERFACE

The pin arrangement of system I/O is shown below.

KP320 SERVICE MANUAL V1.2
65

5-2-12. SIM INTERFACE

The SIM interface module within MTK6229 allows access to the subscriber identity
module smart card. With the appropriate software and level conversion by MT6318,
the interface is compliant with GSM 11.11 and GSM 11.12.

The electrical interface consists of five signals:

SIMVCC

This output connects to contact C306 (VCC) of the SIM connector. It is used to
supply power to the SIM card and is supplied directly from MT6318.
It is controlled by MTK6318 , and enable the power and 3V operation respectively.
Note that while SIMPWR is low, the software sets SIMRST, SIMCLK and
SIMDATA signals low.

SIMRST

This output connects to contact V502 (RST) of the SIM connector. It is set directly
by the CPU writing to the SIM control register.

SIMCLK

This output connects to contact V501 (CLK) of the SIM connector. The clock may
be set high or low, or a choice of 13/4 MHz or 13/12 MHz clock frequencies may
be selected, by writing to the SIM control register. In order to save power, the
clock should be stopped when not required, if the SIM allows it.

SIMDATA

This is a bi-directional, open drain signal, connected to contact V504 (I/O) of the
SIM connector. Control of the data signal is done in the SIM interface section of
MTK6229, although the output can be disabled by writing to the SIM control
register. Being open-drain with an external pull-up, the output floats high when
not being driven low by either Trident-HP or the SIM card.

All the above control signals maintain their state when MTK6229 is powered down.
This allows the SIM to remain powered during soft-OFF. SIMPWR should be
switched OFF when handset ‘hard-OFF’ mode is selected.
