The EMR/EMAR front panel is illustrated above. It contains eight lettered indicator LEDs, a power LED, a [Reset] button, and a fuse holder.

Indicator LEDs

When you first turn on your system (or press [Reset]) the module’s processor runs a series of self tests. The LEDs turn on, then all flash together. Once the tests finish, the LEDs stop flashing. Each indicator LED provides specific information about the operating status of the module, as described below.

Note-Icon-new.png Note: If all LEDs flash simultaneously, the system has encountered a condition that makes it impossible to function. Please contact ETC customer service at 608/831-4116 if this happens. See Backup Jumpers on page 4 for more information.

Reset button

Press [Reset] any time you change the EMR/EMAR's internal jumper settings. (See Configuring the EMR/EMAR on page 3 for more information on jumper settings.) Also, press [Reset] any time you install an EMR/EMAR into a system that has already been turned on.


To remove the fuse, push slightly on the center of the fuse cover with a screwdriver and turn the cover counter-clockwise. Replace the fuse with type 3AG-1 only.
