Powering Up

When applying power to the ISM 824, the unit undergoes a start-up self testing

sequence as follows:
• The LCD screen lights, and displays “Extron Electronics” for 1 second.
• The LCD displays “ISM 824 Version 1.00”.
• All buttons light red, then green, then amber, and then extinguish, leaving the

Video button lit green, the Audio button lit red, and the Menu and Next buttons

both lit amber.

N

If an ISM RGB board is installed, during power up a color bar test briefly

appears on the display device.

• The LCD begins the default display cycle.
N

The complete sequence above is also made when the unit is restarted after

firmware uploads. If the unit is reset via the front panel, the sequence starts at
the default display cycle.

Default display cycle

When in use and not in any menu mode, the LCD screen defaults to cycling

through the output configuration currently installed. The displayed content may

vary from installation to installation, depending on the installed output board

configuration. See figure 3-3 for a typical default display cycle.
