Purchase an antistatic bench kit from a reputable manufacturer and install
and test it according to the manufacturer’s instructions.
Figure 1.1
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 ESD S4.1-1997
(revised) or BS EN 100015-4 1994. The Electrostatic Discharge Association
website is http://www.esda.org/.
Antenna Load
This radio has been designed to operate safely under a wide range of antenna
loading conditions. However, the radio should always be operated with a
suitable load to prevent damage to the transmitter output power stage.

Identifying Screw Types
Torx Recess Head Screws
Torx recess head screws are the standard type of screw used in TM8000
equipment, although Pozidriv head screws are also used in a few special
applications.
The Torx recess head has the advantage of improved screwdriver tip
location, reducing the chances of screw head damage caused by the driver
tip rotating within the recess. In addition, using a ball-tip Torx screwdriver
allows you to drive a Torx head screw with the driver on a slight angle,
which can be useful in situations where access is restricted.
It is important that you use the correct Torx screwdriver tip:
■
M2.5 screws - T8
■
M3 screws - T10
■
M4 screws - T20.
