Important This equipment contains devices that are susceptible to
damage from electrostatic discharge (ESD). Handle every
device carefully and in strict accordance with the
procedures defined in the data book provided by the
manufacturer.
Tait recommends that you purchase an anti-static bench kit from a
reputable manufacturer. The bench must have:
■ a dissipative rubber bench top
■ a conductive wrist strap
■ a connection to ground
Install and test the bench kit in accordance with the manufacturer’s
instructions. See Figure 4.1.
Also take strict anti-static measures when storing, shipping, or carrying
a circuit board or its components:
■ To carry, store, or ship a circuit board use an anti-static bag.
■ To carry, store, or ship a component use foil, an anti-static bag, or an
anti-static tube.
You can also use an anti-static tray to carry a circuit board or component.
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
