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

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-588; RM-593; RM-594; RM-625; RM-629 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.

Touch screen troubleshooting

Introduction to touch screen troubleshooting

RM-588 has a resistive touch screen user interface, which means that the device does not have a traditional ITU-T keypad. The key components of the touch screen user interface are:

•

Touch window with touch controller (TSC2004)

•

Proximity sensor

The resistive touch window is located above the display. It enables finger as well as stylus touch, and it provides tactile feedback. The tactile feedback is implemented by using the same vibra that is used for alerting. The touch controller includes drivers and the control logic to measure touch pressure.

The proximity sensor is attached to the upper flex assembly. It sends out a beam of IR light, and then computes the distance to any nearby objects from the characteristics of the returned (reflected) signal. There is a boot between the sensor and the touch window, which isolates the IR transmitter from the IR receiver by preventing the reflection from the touch window surface.

Proximity sensor troubleshooting

Context

Proximity sensor troubleshooting is broken down into two parts. The main purpose of the automatic check is to identify the fault automatically without any manual checks. If the automatic flow does not provide enough information, a manual check can be done to narrow down the cause of the fault.

Hardware keys troubleshooting

Context

There are two possible failure modes in the keyboard module:

•

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

•

Malfunction of several keys at the same time; this happens when one or more rows or columns are failing (shortcircuit or open connection).

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 2kHz.

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. 1kHz sine wave from 5cm distance.

Required equipment

The following equipment is needed for the tests:

•

Oscilloscope

•

Function generator (sine waveform)

•

Current probe (Internal handsfree PWM output measurement)

•

Phoenix service software

•

Battery voltage 3.7V

•

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

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

•

HP microphone to External earpiece

•

Internal microphone is tested using Phoenix self test "ST-DIGIMIC-TEST". If the test result is PASS, the microphone is electrically OK.

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.
