Page 3: Safety Instructions
Safety Instructions Generally Guide 1. Please check electric circuits before maintenance and change the damaged or over heated components if short-circuit has been found. 2. Please check all protective devices have been installed well after maintenance, such as insulation covering and paper. - Page 4 Please install the electrostatic-sensitive devices on conductor products such as aluminum foil to prevent static build-up after disassembling from this DVB-T receiver. The soldering iron must be earthed while soldering and unsoldering the electrostatic-sensitive devices. Only antistatic solder can be used for electrostatic-sensitive devices disassembly. The electrostatic-sensitive devices will be damaged by static without ESD prevention solder while disassembling.
