Restore factory firmware

and settings on hardware

version 4

c) Press the Accept pushbutton to restore factory firmware and settings.

2) (all hardware versions) If the instrument now functions normally, define your preferred

settings in the Preferences menu, adjust the touch screen again and make necessary

changes to Setup (all accessed via the Main Menu icon).

If you experience problems selecting another template or you login as another user, then note

which step causes the problem. You might need to delete/reconfigure the templates or users.

To delete/reconfigure templates or users, use Measurement Partner Suite BZ-5503 with the

analyzer connected to the PC via Micro USB Cable AO-1494 (G4 hardware) or Mini USB

Cable AO-1476, or a modem/LAN connection. Please consult the on-line help included with

the BZ-5503 software for instructions on how to configure the analyzer.

Re-installing Software (Hardware Versions 1 – 3)

If the instrument still does not work normally after performing the ‘Reset to Default Settings’

procedure, then the software might need to be re-installed. This can be done in two ways:

1) If the connection to Measurement Partner Suite BZ-5503 works with the instrument

connected to the PC using a USB cable, then the software can be re-installed and re-

configured through the USB cable. Please consult the on-line help included with the

BZ-5503 software for instructions on how to re-install software on the analyzer.

2) If the connection to the PC does not work, then you need a Compact Flash card (size at

least 64 Mbytes) and a Compact Flash card reader for the PC. You can then use

Measurement Partner Suite BZ-5503 to update the Compact Flash card with the necessary

files. Please consult the on-line help included with the BZ-5503 software for instructions

on how to update a Compact Flash card with installation files for the analyzer.

Power off the analyzer and insert the compact flash card in the CF slot on the instrument.

Then press and hold down the Manual Event 2 and Save pushbuttons while

switching on the instrument. The Maintenance Mode initial screen will be displayed, and

then within a few seconds the screen shown in Fig.9.4 will appear.
