• BEFORE MAKING ANY TEST CONNECTIONS, MAKE SURE YOU HAVE SWITCHED OFF ALL EQUIPMENT.
Cautions
• Servicing and alignment must be undertaken by qualified personnel only.
• Ensure all work is carried out at an anti-static workstation and that an anti-static wrist strap is worn.
• Ensure solder, wire, or foreign matter does not enter the telephone as damage may result.
• Use only approved components as specified in the parts list.
• Ensure all components, modules, screws and insulators are correctly re-fitted after servicing and
alignment.
• Ensure all cables and wires are repositioned correctly.
• Never test a mobile phone WCDMA transmitter with full Tx power, if there is no possibility to perform the
measurements in a good performance RF-shielded room. Even low power WCDMA transmitters may disturb
nearby WCDMA networks and cause problems to 3G cellular phone communication in a wide area.
• During testing never activate the GSM or WCDMA transmitter without a proper antenna load, otherwise
GSM or WCDMA PA may be damaged.
This product is of superior design and craftsmanship and should be treated with care. The suggestions below
will help you to fulfil any warranty obligations and to enjoy this product for many years.
• Keep the phone and all its parts and accessories out of the reach of small children.
• Keep the phone dry. Precipitation, humidity and all types of liquids or moisture can contain minerals that
will corrode electronic circuits.
• Do not use or store the phone in dusty, dirty areas. Its moving parts can be damaged.
• Do not store the phone in hot areas. High temperatures can shorten the life of electronic devices, damage
batteries, and warp or melt certain plastics.
• Do not store the phone in cold areas. When it warms up (to its normal temperature), moisture can form
inside, which may damage electronic circuit boards.
• Do not drop, knock or shake the phone. Rough handling can break internal circuit boards.
• Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone.
• Do not paint the phone. Paint can clog the moving parts and prevent proper operation.
• Use only the supplied or an approved replacement antenna. Unauthorised antennas, modifications or
attachments could damage the phone and may violate regulations governing radio devices.
All of the above suggestions apply equally to the product, battery, charger or any accessory.
Nokia requires that service points have sufficient ESD protection (against static electricity) when servicing
the phone.
Any product of which the covers are removed must be handled with ESD protection. The SIM card can be
replaced without ESD protection if the product is otherwise ready for use.
To replace the covers ESD protection must be applied.
All electronic parts of the product are susceptible to ESD. Resistors, too, can be damaged by static electricity
discharge.
All ESD sensitive parts must be packed in metallized protective bags during shipping and handling outside
any ESD Protected Area (EPA).
Every repair action involving opening the product or handling the product components must be done under
ESD protection.
ESD protected spare part packages MUST NOT be opened/closed out of an ESD Protected Area.
For more information and local requirements about ESD protection and ESD Protected Area, contact your local
Note: A new battery's full performance is achieved only after two or three complete charge and
discharge cycles!
The battery can be charged and discharged hundreds of times but it will eventually wear out. When the
operating time (talk-time and standby time) is noticeably shorter than normal, it is time to buy a new battery.
Use only batteries approved by the phone manufacturer and recharge the battery only with the chargers
approved by the manufacturer. Unplug the charger when not in use. Do not leave the battery connected to
a charger for longer than a week, since overcharging may shorten its lifetime. If left unused a fully charged
battery will discharge itself over time.
Temperature extremes can affect the ability of your battery to charge.
For good operation times with Ni-Cd/NiMh batteries, discharge the battery from time to time by leaving the
product switched on until it turns itself off (or by using the battery discharge facility of any approved accessory
available for the product). Do not attempt to discharge the battery by any other means.
Use the battery only for its intended purpose.
Never use any charger or battery which is damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object (coin, clip or
pen) causes direct connection of the + and - terminals of the battery (metal strips on the battery) for example
when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery
or the connecting object.
Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce
the capacity and lifetime of the battery. Always try to keep the battery between 15°C and 25°C (59°F and 77°
F). A phone with a hot or cold battery may temporarily not work, even when the battery is fully charged.
Batteries' performance is particularly limited in temperatures well below freezing.
Do not dispose of batteries in a fire!
Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as household waste.
Our policy is of continuous development; details of all technical modifications will be included with service
bulletins.

Measuring power suppliers is usually earlier step during troubleshooting. The following picture illustrates
the test points for power suppliers.

Flash programming does not work
Troubleshooting flow
The flash programming can be done via the pads on the PWB (J2060).
In case of Flash failure in FLALI station, swap the phone and send it back to the care program for further
analysis. Possible failures could be short-circuit of balls under µBGAs (UEMCLite, UPP, FLASH). Missing or
misaligned components. In flash programming error cases the flash prommer can give some information
about a fault. The fault information messages could be:
Because of the use of uBGA components it is not possible to verify if there is a short circuit in control- and
address lines of MCU (UPP) and memory (flash).
This means that the phone does not use any current at all when the supply is connected and/or power key
is pressed. It is assumed that the voltage supplied is 3.6VDC. The UEMCLite/Litti will prevent any functionality
at battery/supply levels below 2.9VDC.
Figure 10 Troubleshooting when the phone doesn't switch on
If this kind of a failure is presenting itself immediately after FLALI, it is most likely caused by ASIC's missing
contact with PWB. If the MCU doesn’t service the watchdog register within the UEMCLite, the operations
watchdog will run out after approximately 32 seconds. Unfortunately, the service routine can not be
measured.
Figure 11 Switch off troubleshooting
Display shows "Contact Service"
Troubleshooting flow
This error can only happen at power up where several self-tests is run. If any of these test cases fails the
display will show the message: "Contact Service".
It's individual test cases so the below lineup of error hunting's has no chronological order. Use common sense
and experience to decide which test case to start error hunting at.
Figure 12 Troubleshooting when the "Contact Service" message is seen
The phone does not register to the networks, or the phone can not make a call
Troubleshooting flow
If the phone doesn't register to the network, the fault can be in either BB or RF. Only few signals can be tested
since several signals is 'buried' in one or more of the inner layers of the PWB.
First of all verify that SIM LOCK is not the reason to cause phone cannot connect to network. The way is to
check if the phone can connect to CMU200 by a test SIM card.
The hardware of the SIM interface from UEMC/Litti (D2901) to the SIM connector (X2700) can be tested without
a SIM card. When the power is switched on the phone first check for a 1.8V SIM card and then a 3V SIM card.
The phone will try this four times, where after it will display ”Insert SIM card”.
The error ”SIM card rejected” means that the ATR message received from SIM card is corrupted, e.g. data
signal levels are wrong. The first data is always ATR and it is sent from card to phone.
For reference a picture with normal SIM power-up is shown below.

Two types of measurements are used in the following. It will be specified if the measurement type is "RF" or
"LF".
• RF measurements are done with a Spectrum Analyzer and a high-frequency probe, for example Agilent
85024A. (Note that the test jig has some losses which must be taken into consideration when calibrating
the test system.)
• LF (Low frequency) and DC measurements should be done with a 10:1 probe and an oscilloscope. The probe
used in the following is 10MW/8pF passive probe. If using another probe then bear in mind that the
voltages displayed may be slightly different. Always make sure the measurement set-up is calibrated when
measuring RF parameters on the antenna pad. Remember to include the loss in the module repair jig when
realigning the phone.
Most RF semiconductors are static discharge sensitive, so ESD protection must be applied during repair
(ground straps and ESD soldering irons). FEM and Uppcosto are moisture sensitive so parts must be pre-baked
prior to soldering. Apart from key-components described in this document there are a lot of discrete
components (resistors, inductors and capacitors) for which troubleshooting is done by checking if soldering
of the component is done properly and checking if the component is missing from PWB. Capacitors can be
checked for short-circuiting and resistors for value by means of an Ohm meter, but be aware in-circuit
measurements should be evaluated carefully. In the following both the name EGSM and GSM850 will be used
for the lower band and both PCN and GSM1900 will be used for the upper band.
Refer to the picture below for measuring points at FEM (N7100) and Litti (D2901).
