Safety and Servicing Information

This chapter contains general information on safety and servicing 
procedures for Tait radio equipment. The procedures described in this 
manual should only be carried out by service personnel trained and 
accredited by Tait Electronics to service encryption-enabled TOP and 
TM8000 radios.

Important

Any modifications you make to this equipment which are 
not authorised by Tait Electronics Ltd may invalidate your 
compliance authority’s approval to operate the equipment.

Equipment Safety

ESD Precautions

Important

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.  The diagram below 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. 

common point ground 
(building ground or 
mains ground via 1M 
ohm series resistor)
