2.1.b Good
practices
In maintaining the equipment covered in this manual, please keep in mind the following, standard good practices:
•
When connecting any instrument (wattmeter, spectrum analyzer, etc.) to a high frequency output, use the appropriate
attenuator or dummy load to protect the final amplifiers and the instrument input.
•
When inserting or removing printed circuit boards (PCBs), cable connectors, or fuses, always turn off power from the affected
portion of the equipment. After power is removed, allow sufficient time for the power supplies to bleed down before reinserting
PCBs.
•
When troubleshooting, remember that FETs and other metal-oxide semiconductor (MOS) devices may appear defective
because of leakage between traces or component leads on the printed circuit board. Clean the printed circuit board and
recheck the MOS device before assuming it’s defective.
•
When replacing MOS devices, follow standard practices to avoid damage caused by static charges and soldering.
•
When removing components from PCBs (particularly ICs), use care to avoid damaging PCB traces.
2.1.c
First aid in case of electrical shock
If someone seems unable to free himself under electric shock contact, turn the power off before rendering aid. A muscular spasm or
unconsciousness can make a victim unable to free himself from the electrical power.
If power cannot be turned off immediately, very carefully loop a length of dry non-conducting material (such as a rope, insulating
material, or clothing) around the victim and pull him free of the power. Carefully avoid touching him or his clothing until free of power.
2.1.d Emergency
resuscitation
technique
Step 1
Check the victim for responsiveness. If there is no response,
immediately call for
medical assistance
, and then return to the person
.
Step 2
Position the person flat on his back. Kneel by his side and place one hand on the
forehead and the other under the chin. Tilt the head back and lift the chin until teeth
almost touch. Look and listen for breathing.
Step 3
If not breathing normally, pinch the nose and cover the mouth with yours. Give two full
breaths. The person's chest will rise if you are giving enough air.
DO NOT TOUCH VICTIM OR HIS CLOTHING BEFORE POWER IS DISCONNECTED
OR YOU CAN BECOME A SHOCK VICTIM YOURSELF
