Resetting the Unit
There are four ways to reset the PCS4 unit (called modes 1, 3, 4, and 5 for the sake of comparison with other Extron IPL products). Reset the unit by pressing the Reset button on the front panel (see “Front Panel Features” for the button location). This button is recessed; it can be accessed with a pointed stylus, ballpoint pen, or small Phillips screwdriver.
CAUTION: The reset modes described on the following pages break all TCP/IP connections by closing all sockets to the unit.

CAUTION: Review the reset modes carefully. Use of the wrong reset mode may result in 
unintended loss of flash memory programming or a unit reboot.
NOTES: • If the Reset button is continually held in, the LEDs pulse (blink) every
3 seconds, and the PCS4 is put in a different mode, corresponding to the
underscored notes in modes 3 through 5. The mode 5 LED blinks three times,
the third blink indicating that it is the last mode.
• The reset modes are separate functions, not a progression from mode 1 to mode 5.
Mode 1

| issues arise. All user files and settings are maintained. User web |
| pages may not work correctly if you are using an earlier firmware |
