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 90 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.
