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.
