Instruction book, IQAN- MD3

Internal Diagnostics

The IQAN-MD3 has a diagnostics page. This page can be useful for obtaining 
diagnostic information. To view the test page, press the menu and escape buttons 
simultaneously and hold during power up. To exit test mode, turn the unit off and 
power up normally.

Accessing the diagnostics page.

Safe mode

If necessary, the IQAN-MD3 may be started in safe mode. When started in safe mode, 
no application is loaded and nothing is running. The screen shows a default background 
and a dialog box notifies the user that the unit is in safe mode. This can be useful for 
installing an IQAN-MD3 with an unknown application in memory, when retrofitting of 
new hydraulic components has occurred or if a user has somehow changed the 
application in an unacceptable way. To start in safe mode, press the escape button and 
hold during power up. In safe mode you can then upload a new application to the 
IQAN-MD3. To exit safe mode, turn the unit off and power up normally.
