You can obtain further information on antistatic precautions and the dangers
of electrostatic discharge (ESD) from standards such as ESD S4.1-1997
(revised) or EN 100015-4 1994. The Electrostatic Discharge Association
website is http://www.esda.org/.
Storage and
Transport
of Items
Always observe anti-static precautions when storing, shipping or carrying
the circuit boards and their components. Use anti-static bags for circuit
boards and anti-static bags or tubes for components that are to be stored or
shipped. Use anti-static bags or trays for carrying circuit boards, and foil or
anti-static bags, trays, or tubes for carrying components.
Anti-static
Workbenches
Use an anti-static workbench installed and tested according to the
manufacturer’s instructions. A typical installation is shown in Figure 4.1.
These benches have a dissipative rubber bench top, a conductive wrist strap,
and a connection to the building earth. The material of the bench top must
satisfy not only anti-static requirements but also the non-scratch
requirements mentioned above.
Transmitter Issues The following issues relate to the operation of the transmitter:
■ RF and thermal burns
■ antenna loading
■ test transmissions
■ accidental transmissions
■ distress beacons.
The precautions required in each case are given below.
Caution Avoid thermal burns. Do not touch the cooling fins
or underside of the radio body when the transmitter
is or has been operating. Avoid RF burns. Do not
touch the antenna while the transmitter is operating.
Important The radio has been designed to operate with a 50Ω
termination impedance. Do not operate the transmitter
