Safety Precautions; Repair Precaution - Samsung GT-i9100 Service Manual

1. Safety Precautions

1-1. Repair Precaution

― Repair in shield box during detailed tuning.
Take specially care of tuning or test because the specification of mobile phone is sensitive for
surrounding interference(RF noise).
― Be careful to use a kind of magnetic object or tool because performance of parts is damaged by
the influence of the magnetic force.
― Surely use a standard screwdriver when you disassemble this product.
― Use a thicken twisted wire when you measure level because a thicken twisted wire has low
resistance.
― Repair after separate test pack and set because of short danger (for example an overcurrent and
furious flames of parts etc) when you repair the board in condition of connecting Test Pack and
tuning on.
― Take specially care of soldering iron because the board of the PCB is small and weak in heat.
― Surely tune on/off while using AC power plug because a repair of battery charger is dangerous
when tuning ON/OFF PBA and Connector after disassembling the charger.
― Don't use the unauthorised materials except for the replacement registered on SEC System.
Otherwise the engineer isn't charged with issues that you don't keep.
