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.

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-Pol 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.

Display module troubleshooting

General instructions for display troubleshooting

The first step is to verify with a working display that the fault is not on the display module itself. The display
module cannot be repaired. The second step is to check that the engine is working normally. This can be

Alphamon technical description and troubleshooting

Proximity sensor and ambient light sensor (ALS)

This phone uses a combined proximity and ambient light sensor called Alphamon. The proximity sensor is
integrated to the module and uses an internal LED supplied by VBAT. The current this LED consumes is
controlled by Alphamon and set using software. The interrupt output of Alphamon changes state when the
infra red light from the LED is reflected back by a suitable reflective surface. The ambient light sensor detects
the level of ambient light and adjusts the display brightness accordingly whenever the display is active.
Covering this sensor results in dimmed display lights.

Run Proximity from the ODDT tool to verify that it works. Use a finger to hide the Alphamon sensor window,
the light intensity in mLux changes from 0 to approx. 130 000.

Note: The light intensity could vary depending on how the finger hides the Alphamon window.

Audio troubleshooting

Audio troubleshooting test instructions

Single-ended external earpiece and differential 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 2 kHz.

The input signal for each loop test can be either single-ended or differential. Exception to this is a digital
microphone which needs input signal from an external sound source (laptop speaker) to playback, eg. 1 kHz
sine wave from 5 cm distance.

Required equipment

The following equipment is needed for the tests:

•

Oscilloscope

•

Function generator (sine waveform)

•

Current probe (Internal handsfree DPMA output measurement)

•

Service software

•

Battery voltage 3.7V

•

Sound source (laptop speaker or B&K type 4231 calibrator)

Test procedure

Audio can be tested using the application in NWP. Three different audio loop paths can be activated:

•

XMIC to XEAR (L) and (R)

•

MIC1 to EAR

•

MIC1 to IHF

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 the application.

Connectivity module troubleshooting

Introduction to connectivity module troubleshooting

The BOB1.0M-a module supports WLAN, BT and FMRX. From a troubleshooting point of view, WLAN is tested
separately, but BT and FMRX are checked in parallel.

REFCLK_I single ended 38.4 MHz analog clock from an external crystal (G6300) is provided to BOB1.0M-a. The
clock request for the reference clock in the BOB1.0M-a module is shared between WLAN and BT blocks. When
either system requires a clock, this signal will be active. The CLK_REQ is connected to LDO of 38.4 Mhz crystal.
The SLEEPCLK input of 32.768 KHz clock from EM ASIC (PMIC 8058) is used for power management and for FM
in low power mode. The internal SMPS supplies the whole BOB1.0M-a solution from the phone battery supply,
VBAT, apart from VIO which is needed for interface signal reference levels.

The following figure shows a top level block diagram of the BOB1.0M-a module.

the backside of the unibody. The WLAN/BT signal is routed from the connectivity module through the RF
diplexer and a shared GPS/WLAN antenna is used. The FM receiver RF signal is routed through an FM antenna
matching circuit to the phone headset connector. The FM radio audio signal is routed to the headset connector
through the BB ASIC shared by the phone audio functions.
