4. GENERAL REPAIR INFORMATION
In this section you will get some general hints how to carry out repairs:
o Before starting the repair you must take care of ESD precautions like being in your ESD-area and
connecting your wristband.
o Use gloves to avoid corrosion and fingerprints.
o Protect windows and displays with a foil to avoid dust and scratches.
o When cleaning the pads you have to use a soft cloth and isopropanol. It is not allowed to use a

o Mechanical parts, which didn’t repair the failure, can be reused, if they are not soldered.
o Use always original Nokia parts or accessories.
o Meet the torque requirements when assembling the unit (see also the document “torques for
transceiver assembly” on Partner Websites).
o Always use your own equipment for testing where you are sure that it works. E.g. if the customer
complains about charger function, please test the phone with your own charger to be sure if
phone or charger causes the malfunction.
