Electronic and Electrical Components Working on Electronic and Electrical Components
PCAs and ICs are sensitive to ESD. ESD can damage electronic parts.
While removing PCAs or handling ESD sensitive parts:
• Touch an unpainted metal surface to discharge any static electricity build-up.
• Use a wrist strap connected to a grounded metal frame or chassis.
• Place the removed PCAs or ICs on a grounded anti-static mat.
• Use an IC extractor tool to remove the undergirded circuits.
• Place all PCAs you plan to return for credit or repair in anti-static bags.

Replaceable Batteries
Some PCBs contain replaceable batteries. Insert all the batteries correctly.

with the same or equivalent type of batteries recommended. Dispose of the used
batteries as per battery manufacturer’s instructions. Ensure that you replace the
batteries in the correct polarity position to avoid damage to the equipment.

WARNING
Replacing Fuses
To ensure equipment protection and maintenance of safe operation, always use the correct
replacement fuse. Using an incorrectly sized or type fuse may cause equipment damage. The
type of fuse is also very important. Some fuses even with the same amperage rating are
designed to respond differently to over current and so on.
CAUTION
Helpful Service Information
Some boards include information that helps in correct or faster servicing. Be aware of the
following found on many boards:
• Cable connectors are labeled with the destination of the cable.
• Test points are clearly labeled and recessed to facilitate the use of meter probes.
• Test point labels indicate an acceptable electrical range. For example, 4.8-5.2 VDC.
