This equipment contains CMOS devices which are susceptible to dam-
age from static charges.  Refer to Section 1.2 in Part A for more infor-
mation on anti-static procedures when handling these devices.

The following test procedures and fault finding flow charts may be used to help locate a
hardware problem, however they are by no means a complete fault finding procedure.
If you still cannot trace the fault after progressing through them in a logical manner,
contact your nearest Tait Dealer or Customer Service Organisation.  If necessary, you can
get additional technical help from Customer Support, Radio Systems Division, Tait Elec-
tronics Ltd, Christchurch, New Zealand (full contact details are on page 2).

In this and following sections deviation settings are given first for wide

Unless otherwise specified, the term "PGM800Win" used in this and follow-
ing sections refers to version 2.00 and later of the software.
