Care and maintenance

Care and maintenance
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.

RM-497 ESD protection

ESD protection

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
Nokia After Market Services representative.

Battery information

Battery information
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.

Introduction to BB Troubleshooting

Nearly all of the functions of the phone are contained within or controlled by the D2800 Juno BB ASIC so most of the debugging will be centered there. The D2800 Juno BB ASIC is static sensitive so precautions must be taken to avoid damaging this or other devices from excessive ESD.

Baseband self tests in Phoenix

Context
Always start the trouble-shooting procedure by running the Phoenix self tests. If a test fails, please follow the diagram in the
If the phone is dead and you cannot perform the self-test, please go to

The 32 kHz crystal is connected to the N2201 PMU and is transmitted to the D2800 Juno BB ASIC.
The 26 MHz crystal is connected directly to the D2800 Juno BB ASIC. The D2800 Juno BB ASIC can output four copies of the 26 MHz input clock from it’s CK1, CK2, RF_XON, and RF_XOP pins, however, only the RF_XON output is used.
Note: All test-points are located under the RF shielding.
1) 32 kHz crystal (B2200) The 32 kHz clock to the N2201 Loviisa can be tested by setting the oscilloscope probe on R2209.
2) 26 MHz crystal (B2800)
The 26 MHz clock to the D2800 Juno can be tested by setting the oscilloscope probe on B2800.
The RF_XON output clock can be tested by probing C6094 near the BT/FM module.
Note: This step will require the RF_XON output clock for BT/FM module to be enabled through

Audio troubleshooting

Audio troubleshooting test instructions

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 1kHz.
The input signal for each loop test can be either single-ended or differential.
Required equipment
The following equipments are 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 signal 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 different output vs. single-ended/different input.

General RF troubleshooting

Introduction to RF troubleshooting

Most RF semiconductors are static discharge sensitive
ESD protection must be applied during repair (ground straps and ESD soldering irons).
Pre-baking
These parts are moisture sensitive and must be pre-baked prior to soldering:
Juno D2800
Front End Module N7500
Discrete components
In addition to the key-components, there are a number of discrete components (resistors, inductors, and capacitors) for which troubleshooting is done mainly by
Capacitors: check for short circuits. Resistors: check value with an ohm meter. Inductors: check for open circuits.
Note: In-circuit measurements should be evaluated carefully.
visual inspection
.
Measuring equipment
All measurements should be done using:
An oscilloscope for low frequency and DC measurements. Recommended probe: 10:1, 10Mohm//8pF.
A radio communication tester including RF generator and spectrum analyser, for example Rohde & Schwarz CMU200. (Alternatively a spectrum analyser and an RF generator can be used. Some tests in this guide are not possible to perform if this solution is chosen).
Note: All measurements with an RF coupler should be performed in an RF-shielded environment
because nearby base stations can disturb sensitive receiver measurements. If there is no possibility to use RF shielded environment, testing at frequencies of nearby base stations should be avoided.
Level of repair
The scope of this guideline is to enable repairs at key-component level. Some key-components are not accessible, i.e. not replaceable. Please refer to the list of Non-replaceable RF components.
Note: After the RF shielding can is removed (for measurement or repair), it must be replaced with
a new one and cannot be reused.

FEM Control Signal

When troubleshooting the FEM, it’s important to check its’ control signal. If the control signal didn’t operate correctly, FEM might not turn on or it might turn on in different mode. Table xxx shows the control logic for TX_EN, BS1, BS1, MODE, and TX_SW_EN. Figure xxx shows the timing diagram that one expects when probing these signals.

Introduction to receiver (RX) troubleshooting

RX can be tested by making a phone call or in local mode. For the local mode testing, use Phoenix service software.
The main RX troubleshooting measurement is the GSM RSSI reading. This test measures the signal strength of the receive signal.
