PROGRAMMING
The radios personality is programmed using an IBM PC
or compatible computer. A full-screen portable PC can be
used for field programming. The Programming Manual and
Software is TQ-3364. This package includes both 5-1/4
floppy and 3-1/2 inch disks. The programming software
uses a series of screens and windows to guide you through a
programming session. See TQ-3364 for further program-
ming details. PC Programming Adapter TQ-3370 and Pro-
gramming Cable TQ-3311 will also be required. These
items provide interface and connection between the PC and
the radio when the personality is transferred from the PC
into the radio.
