2. GENERAL REPAIR INFORMATION
IN THIS SECTION THE TECHNICIAN WILL GET SOME GENERAL HINTS HOW TO CARRY OUT REPAIRS:
o
To familiarize oneself with Nokia 3100 read the user guide on
www.nokia.com
-->Support--> Phones,
by selecting the Phone Model.
o
Before starting the repair you must take care of ESD precautions like being in your ESD Protected Area
and connecting your wristband.
o
Use gloves to avoid corrosion and fingerprints.
o
Protect windows and displays with a film to avoid dust and scratches.
o
When cleaning the pads you have to use a soft cloth/ESD brush and Isopropanol. It is not allowed to use
a glass fiber pencil because it scratches the surface and will lead later on to corrosion.
o
Mechanical parts (except shielding lids), which didn’t repair the failure, can be reused, if they are not
soldered.
o
When removing the shielding lids make sure to replace them with new ones, otherwise the high-
frequency leakage can have an influence on the device.
o
Use always original Nokia spare parts.
o
Check the soldering joints of the parts which are concerned regarding the indicated error
(e.g. soldered connectors or switches) and resolder them if necessary (Level 2 only).
o
Remove redundant soldering flux after repair.
o
Meet the torque requirements when assembling the unit (see also the document “torques for
transceiver assembly” on Nokia Partner Web Site).
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.
o
When doing the Faultlogger entries, always note the Item code, which caused the malfunction. Also, fill
in the appropriate part code from the assembly, if needed.
o
Please be aware that some malfunctions could be software related and solved by an update.
