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.
3. Please finish following electrical leakage tests after maintenance to avoid electric shock.
Low Voltage Leakage Testing
Take out power cord from an AC outlet and connect a length of wire between the two leads of the plug.
Use Gear R x 10K of the voltmeter to measure the resistance between shorted-out AC plug and exposed
metallic parts like screw cap, control shaft etc. which shall be infinite.
Picture 1
High Voltage Leakage Testing
As shown in Picture 1, connect a resistor of 1.5K, 10W and capacitor of 0.15 uF between exposed metallic
part and well grounded devices (water pipe etc.).
Plug power cord directly into the socket. Do not use insulated transformer to test.
Use 1000 Ohm/V or more sensitive voltmeter to measure AC voltage of the resistor.
Turn over the AC jack and plug into the socket again to iterate the inspection as above.
Inspect the voltage of the resistor between other exposed metallic parts and the earth in the same way.
Any parts’ voltage of the resistor should not over 0.75Vrms. A leakage testing machine with voltage over
2,500 V can also be used for this inspection in which case the electric leakage should not be over 0.5mA. When
the leakage exceeds that limit, electric shock may occur. Please check and repair again before hand it over to
users.
4. Protect Electrostatic-Sensitive Devices from Electrostatic Discharge
Some solid states made of semiconductors materials can be easily damaged by commonly static charges,
those components are usually called electrostatic-sensitive devices. Such like integrated circuits, laser diodes
and field effect devices. The following tips will help you to reduce the impacts on those components while
electrostatic discharging.
Please release static which build-up on human body before handling electrostatic-sensitive devices by using
grounded tools. The antistatic strap which can be found in the market will be a good choice.

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.
Do not use Freon Volatile which may damage the electrostatic-sensitive devices by discharging static.
Do not take the new electrostatic-sensitive devices from the antistatic protection package unless you are
ready for installation. (Most electrostatic-sensitive devices will be packed with anti-static foam, foil or similar
conductive materials. And a lead wire to prevent short circuit.)
Please contact the core or circuit parts of the device to be installed with ESD protection package before carry
out the new electrostatic-sensitive devices from it. And make sure no power supply on the device and remember
other precautions.
Try to reduce body movements while assembling or disassembling electrostatic-sensitive devices. (Clothes
made of fabrics will build-up static by attrition. Feet lifts up from floor will also build-up static.)
