1. Safety Precautions 1-1. Repair Precaution ― Repair in Shield Box, during detailed tuning. Take specially care of tuning or test, because specipicty of cellular 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 magnetic force. ― Surely use a standard screwdriver when you disassemble this product, otherwise screw will be worn away. ― Use a thicken twisted wire when you measure level.
Safety Precautions 1-2. ESD(Electrostatically Sensitive Devices) Precaution Several semiconductor may be damaged easily by static electricity. Such parts are called by ESD (Electrostatically Sensitive Devices), for example IC,BGA chip etc. Read Precaution below. You can prevent from ESD damage by static electricity. ― Remove static electricity remained your body before you touch semiconductor or parts with semiconductor.
