Section 4 Programming Instructions; Menu Screens - Sony CMD-Z1 Service Manual

1. Setup
The programming jig is based upon a PC-linked application.
Minimum requirement for PC is IBM compatible, 386 type.
The software is a basic MS− DOS application. Please do NOT run it as a DOS mode application starting from a
Windows program. It is necessary to exit Windows when starting the PC-link application, or preferrably to start
the PC without entering Windows.
The jig consists of: Level Convertor, Connection Cables (PC to Level Convertor and Level Convertor to CMD− Z1)
and application software on floppy disc.
No specific software installation is needed; only copy all the files from the floppy disc to the PC, ideally into a
dedicated directory.
Starting of the software updating program will take place when going to the directory where you have loaded
the application program and typing CMD− Z1 + enter.
2. Important notes
•
Before connecting the CMD− Z1 to the level convertor, take out the battery of the CMD− Z1; the CMD− Z1
must be powered from the level convertor.
•
Whenever the program is in progress, or when the level convertor is powered on, never disconnect or connect
any cables.
•
Never interrupt the power supply to the level convertor whenever a software update is in progress.
•
The level convertor has some switches; please make sure they are in the correct position. These switches
are included also to allow future changes, or other applications.
