1-3.9 Restrictions; Safe Handling Of Cmos Devices - Motorola MICOM-3F Service Manual

Warning

1-3.9 Restrictions

Because this radio contains a transmitter, federal law prohibits unauthorized, non-licensed personnel
from adjusting or maintaining it. If any operational difficulties should arise while using this product,
report them to authorized service personnel as soon as possible.
Warning

1-4. Safe Handling of CMOS Devices

Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios. While
the attributes of CMOS are many, their characteristics make them susceptible to damage by
electrostatic or high voltage charges. Damage can be latent, resulting in failures occurring weeks or
months later. Therefore,
disassembly, troubleshooting,
are especially important in low humidity conditions.
Caution
1. Eliminate static generators (plastics, styrofoam, etc.) in the work area.
2. Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back
loose hanging neckties.
3. Store and transport all static-sensitive devices in ESD protective containers.
4. If at all possible, handle CMOS devices by the package and not by the leads. Prior to touching
the unit, touch an electrical ground to remove any static charge that you may have
accumulated. The package and substrate may be electrically common. If so, the reaction of a
discharge to the case would cause the same damage as touching the leads.
5. Disconnect all power from the unit before ESD sensitive components are removed or inserted,
unless otherwise noted.

Blasting Caps and Blasting Areas
To avoid possible interference with blasting operations, turn off warning
your radio when you are near electrical blasting caps, in a blasting area,
or in areas posted: "Turn off two-way radio". Obey all signs and
instructions.
For radios installed in vehicles fueled by liquefied petroleum gas, refer to
the (U.S.) National Fire Protection Association standard, NFPA 58, for
storage, handling, and/or container information. For a copy of the LP-gas
standard, NFPA 58, contact the National Fire Protection Association, One
Battery Park, Quincy, MA.
Do not attempt any unauthorized modification to the radio.
special precautions must be taken to prevent device damage during
and repair. Handling precautions are mandatory for CMOS circuits and
Do not attempt to disassemble the radio without observing the following
handling precautions.
