• IF THE DEVICE CAN BE INSTALLED IN A VEHICLE, CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED
WITH ELECTRONIC ENGINE MANAGEMENT SYSTEMS AND ANTI-SKID BRAKING SYSTEMS. UNDER CERTAIN FAULT
CONDITIONS, EMITTED RF ENERGY CAN AFFECT THEIR OPERATION. IF NECESSARY, CONSULT THE VEHICLE DEALER/
MANUFACTURER TO DETERMINE THE IMMUNITY OF VEHICLE ELECTRONIC SYSTEMS TO RF ENERGY.
• THE PRODUCT MUST NOT BE OPERATED IN AREAS LIKELY TO CONTAIN POTENTIALLY EXPLOSIVE ATMOSPHERES,
FOR EXAMPLE, PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC.
• OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLULAR TELEPHONES, MAY INTERFERE
WITH THE FUNCTIONALITY OF INADEQUATELY PROTECTED MEDICAL DEVICES. CONSULT A PHYSICIAN OR THE
MANUFACTURER OF THE MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS. OTHER ELECTRONIC EQUIPMENT MAY
ALSO BE SUBJECT TO INTERFERENCE.
• 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 Li-Ion 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.

Bad conditions often cause bad pictures. Therefore, the camera operation has to be checked in constant
conditions or by using a second, known-to-be-good Nokia device as reference. Image quality is hard to
measure quantitatively, and the difference between a good and a bad picture can be small. Some training
or experience may be needed to detect what is actually wrong.
When checking for possible errors in camera functionality, knowing what error is suspected significantly
helps the testing by narrowing down the amount of test cases. The following types of image quality problems
are common:
• Dust (black spots)
• Lack of sharpness
• Bit errors
Main (back) camera troubleshooting
Taking and evaluating test pictures with main camera
When
• Avoid bright fluorescent light, 50/60Hz electrical network or high artificial illumination levels
• If the phone is hot, let it rest for a while before taking the picture
• Make sure the optical system is clean
• Use highest possible resolution
• Make sure the light is sufficient (bright office lightning)
• Do not take the picture towards a light source
• Hold the phone as still as possible when taking the picture
• If camera has auto focus: Pictures should be taken both at infinity ~>2m and at macro distance ~10-15 cm
When
• The center of the picture is sharper than the edges
• The image may be blurred, though it does not show in the viewfinder
• Analyse the picture from your PC monitor, full colour setting is recommended
• If possible, compare with a picture of the same motive taken with a similar Nokia device
• If camera has auto focus: Remember that the white focussing frame which appears when the camera
taking

button is pressed halfway down, must turn green for auto focus lock. If the frame turns red, the camera
is not focussed!
Note: Phone must be in a video call for the front camera to be active.
Note: Always use the "troubled" phone when evaluating a picture in a video call. Do not evaluate
the picture on the receiving phone.

Differential external earpiece and internal earpiece outputs can be measured either with a single-ended or
a differential probe.
When measuring with a single-ended probe each output is measured against the ground.
Internal handsfree output is measured using a current probe, if a special low-pass filter designed for
measuring a digital amplifier is not available. Note also that when using a current probe, the input signal
frequency must be set to 2kHz.
The input signal for each loop test can be either single-ended or differential.
Required equipment
The following equipment is needed for the tests:
• Oscilloscope
• Function generator (sine waveform)
• 'Active speaker' or 'speaker and power amplifier'
• Sound level meter
• Current probe (Internal handsfree DPMA output measurement)
• Phoenix service software
• Battery voltage 3.7V
Test procedure
Audio can be tested using the Phoenix audio routings option. Three different audio loop paths can be
activated:
• External microphone to Internal earpiece
• External microphone to Internal handsfree speaker
• Internal microphone to External earpiece
Each audio loop sets routing from the specified input to the specified output enabling a quick in-out test.
Loop path gains are fixed and they cannot be changed using Phoenix. Correct pins and signals for each test
are presented in the following table.
Phoenix audio loop tests and test results
The results presented in the table apply when no accessory is connected and battery voltage is set to 3.7V.
Earpiece, internal microphone and speaker are in place during measurement. Applying a headset accessory
during measurement causes a significant drop in measured quantities.
The gain values presented in the table apply for a differential output vs. single-ended/differential input.
Figure 13 Single-ended output waveform of the Ext_in_HP_out measurement when earpiece is connected.
If a special low-pass filter designed for measuring digital amplifiers is unavailable, the measurement must be performed with a
current probe and the input signal frequency must be 2kHz.
Figure 14 Differential output waveform of the Ext_in_IHF_out out loop measurement when speaker is connected.
This procedure is performed when the device certificate is corrupted for some reason.
All tunings (RF & Baseband, UI) must be done after performing the certificate restoring procedure.
The procedure for certificate restoring is the following:
• Flash the phone with the latest available software using FPS-8 or FPS-10.
Note: USB flashing does not work for a dead BB5 phone.
• Create a request file.
• Send the file to Nokia by e-mail. Use the following addresses depending on your location:
