2.2 Equipment Safety
2.2.1 Installation and Servicing Personnel
The equipment should be installed and serviced only by qualified
personnel.
2.2.2 Preventing Damage to the PA
The base station has been designed to operate safely under a wide range of
antenna loading conditions. Transmitting into a low VSWR will maximize
the power delivered to the antenna.
Notice Do not remove the load from the PA while it is transmitting.
Load transients (switching or removing the load) can damage the PA output
stage. See “Connecting RF” on page 83 for recommendations.
2.2.3 ESD Precautions
Notice This equipment contains devices which are susceptible to
damage from static charges. You must handle these devices carefully
and according to the procedures described in the manufacturers’ data
books.
We recommend you purchase an antistatic bench kit from a reputable
manufacturer and install and test it according to the manufacturer’s
instructions. Figure 2.1 shows a typical antistatic bench set-up.
You can obtain further information on antistatic precautions and the
dangers of electrostatic discharge (ESD) from standards such as ANSI/
ESD S20.20-1999 or BS EN 100015-4 1994.
