2.3 Disassembly and Assembly Instruction
2.3.1 Disassembly Instruction
The procedure for mobile disassembly is described in the instruction GFZ13136904 – TRIUM 110
Disassembly (M6A+ Cupid).
2.3.2 Assembly Instruction
The procedure for mobile assembly is described in the instruction GFZ13136903 – TRIUM 110
Assembly (M6A+ Cupid).
3Download
The data are divided in two parts: the software and the settings.
Currently the Mitsubishi software ( .bin file ) is downloaded into the Flash and the setting ( . pso file ) is
downloaded into an EEPROM or Serial Flash.
The M6A+ mobiles does not use EEPROM but a Flash Data and the setting are not in .pso extension
but in .psb (as M6A). The main consequence of this change is that the new setting file .psb MUST
BE DOWNLOADED WITH IPL TRIUM.
In conclusion, with the M6A product, the software and the setting can be downloaded in the same time
by using IPL Trium.
3.1 Download of Software and settings
The configuration to download software is :
Launch MT ToolsV103.02 or higher, select the “Mobile Type M5-M6A” and then launch IPL Trium in
download/download software menu.

4Basic Adjustment
For M6 family, test mode is not directly possible from the mobile, indeed relevant software is available
on PC only.
Thanks to the new generation of MT Tools (MT Tools 2000), we can either repair Level 2 or Level 3.
4.1 Equipment installation
The test mode is used to control or adjust mobile parameters.
You must have the following requirements :
•Radio-communication tester
•M5 RF cable
•M5 Interface cable
•M4 / M5 Interface Box
•Serial Cable
•Computer under Windows 95 minimum (PII 350 MHz 64 Mb recommended)
•An ampermeter can be installed between the external supply and the interface box to check the
mobile consumption.

9.1.2 Battery management
9.1.2.1 Block Diagram / Description
Regarding the CUPID, the battery is Li-Ion 800 mAh, 3.8 V, whereas the external power supply is 5.7 V, 600 mA nominal.

EXPS:
AC/DC
CLA
HF kit
3.6 V nominal
SPI interface
When an external power supply is
plugged, the voltage of EXPS
2
is 5.7 V,
therefore battery does not supply
anymore the Base Band (via IPD
regulators). Indeed, the voltage from the
EXPS is always greater than the one from
battery, the diode D100 is no more
opened.
Nevertheless, some parts of the radio are
only supplied by the battery.
Battery presence is accessible in CHGM
IPD register. The battery level information
is accessible in an A/D converter in One-
C. It is also available in CHGM IPD
register, these information are given by
range only for range control.
The battery temperature information (TH) is given by thresholds in IPD CHGM register. This information are used only for
charge control.
Bypass is Activated when battery is less than 3.45 V.
The regulator IC103 is to make the power supply 2.5RTC for the One C.
9.1.2.2 Charging process
The IPD charger, supplied by EXPS achieves the charge. The charge process is done by an internal algorithm controlled by
S/W.
The 1C current charge is fixed by hardware to 420 mA, so that a complete charge duration is about 130 min at room
temperature.
Charging process follows these successive phases:
1. Pre charge:
This phase is mandatory before the rapid charge to verify that battery operation is normal (normal battery voltage and
temperature). Charge current during this phase is 52 mA ( 8
1C). If the battery voltage is higher than 3.4 Volts, the S/W
launches IPD charger in Rapid charge except if the temperature is not between 0°C and 55°C.
2. Rapid charge:
Charge current during this phase is 420mA. If battery temperature becomes abnormal IPD charger start at low current
charge
(
)
C
20
1, while temperature comes back normal (between 0°C and +55°C) during 15 min.
Full charge detection ends Rapid charge. Full charge is detected by S/W when one out of the three evens occurs:
•Battery voltage begins to decrease
(
)
V∆−
•Battery voltage stops to increase during 20 min
(
)
V∆
•Rapid charge time is expired (150 min)

Trickle charge is automatically stopped after 24 hours duration.

10.2 Synthetiser Circuit Description.
Switching between GSM and DCS band is performed by programming the IC401 with the serial data in BBE from CPU.
The serial data lines are connected directly to the serial input pin of the RF IC (IC 401), and are used to program the 2 PLLs of
the IC.
The RF IC has two PLLs : one is variable frequency (RF PLL), and the other is fixed frequency (IF PLL).
RF-PLL : variable frequency PLL for RX and TX for both GSM and DCS bands.
Oscillation Frequency Ranges : - For E-GSM Band / 1150 - 1185MHz
-For DCS TX / 1575 - 1650MHz
-For DCS RX / 1580 - 1655MHz
IF-PLL : Fixed frequency 424 MHz for IF of TX for both E-GSM and DCS bands.
Fixed frequency 360 MHz for IF of RX for both E-GSM and DCS bands.
The signal BANDSW controls the E-GSM/DCS Band switching.
