1 About this manual
This manual provides a technical description, details and drawings of the 9323,
9360, 9390 or 9780 transceiver. It should be used as a guide to the function,
technical operation, fault diagnosis, dismantling, assembly, set up and adjustment
of this series of transceivers.
This manual assumes that you have a technical background in electronics.
The manual contains nine chapters:
Chapter 2 provides an overview of the features of the 9323, 9360, 9390 or 9780
transceiver, including specifications.
Chapter 3 provides a brief description of the 9323, 9360, 9390 or 9780 transceiver
including a general description of the major circuit functions for the control,
reception and transmission of signals.
Chapter 4 provides a more detailed technical description of the operation and
circuit function of the 9323, 9360, 9390 or 9780 transceiver. Read this with the
associated technical drawings found in Chapter 9.
Chapter 5 provides details of maintenance, fault diagnosis procedures and general
cautions and warnings associated with the 9323, 9360, 9390 or 9780 transceiver.
Chapter 6 provides programming procedures for channel additions.
Chapter 7 provides adjustments, checks and alignments to the 9323, 9360, 9390 or
9780 transceiver. A list of required test equipment is included.
Chapter 8 contains the parts lists for the 9323/9360/9390/9780.
Chapter 9 contains the circuit and layout drawings for the 9323/9360/9390/9780
transceiver.
