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.

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.

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 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.

Context

There are two possible failure modes in the keyboard module:

•

One or more keys are stuck, so that the key does not react when a keydome or a side key is pressed. This
kind of failure is caused by mechanical reasons (dirt, rust, mechanical damage, etc.)

Page 3 – 24 COMPANY CONFIDENTIAL Issue 1

RM-645
BB Troubleshooting and Manual Tuning Guide

•

Malfunction of several keys at the same time. This happens when one or more rows or columns in the key

matrix are failing (shortcut or open connection).
If the failure mode is not clear, start with the Keyboard test in Phoenix.
In this phone the keyboard is connected to D2800 I/O pins.

Required equipment

The following equipment is needed for the tests:

•

Oscilloscope

•

Function generator (sine waveform)

•

Phoenix service software

•

Battery voltage 3.7V

Test procedure

Audio can be tested using the Phoenix audio routings option. Three different audio loop paths are used in
the tests:

•

AV mic to AV ear

•

AV mic to HP ear

•

Ext microphone in Int handsfree out

Note: The internal uplink microphones can be tested using the Phoenix self test "ST-DIGIMIC-TEST".

If the test result is PASS, the uplink microphones are electrically OK. For more thorough testing, see
section

Each audio loop sets routing from the specified input to the specified output enables 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 a table in the following section.

Acoustics troubleshooting

Introduction to acoustics troubleshooting

Acoustics design ensures that the sound is detected correctly with a microphone and properly radiated to
the outside of the device by the speaker. The acoustics of the phone include three basic systems: earpiece,
stereo integrated handsfree (IHF) and digital microphone.

The sound reproduced from the earpiece readiates through a single hole on the front cover (A-cover). The
sound reproduced from the 2 IHF speakers radiates from the sound holes located on the bottom part of the
back cover. The microphone is located on the top side of the PWB, and the sound hole is in the keyboard near
the 0-key.

For a correct functionality of the phone, all sound holes must be always open. When the phone is used, care
must be taken not to close any of those holes with a hand or fingers. The phone should be dry and clean,
and no objects must be located in such a way that they close any of the holes.

Receiver self test

Context

Receiver self test can be used to check the correct functionality of the receiver core. For the test, GPS software
configures internal test source to generate synthetic GPS-like data, processing it in the baseband and writing
the results into the channel processor memory. The test compares the data in the channel memory against
the expected value and reports a PASS/FAIL status.

Steps

1. Start Phoenix service software.
