3.1.3 Display Error Codes

Error codes are displayed on the left side of the LCD as shown in Figure 3-2. If an
error is detected the appropriate error code is displayed on the LCD. There are
three error codes:
E1
E2
E3
The Maintenance and Troubleshooting section, Section 4, contains information
about how to resolve these errors.
Error code E1 indicates a power supply error. The regulated power supplies inside
the 1900/27 monitor are continuously checked. If they fall outside of the
acceptable power supply range the monitor displays the E1 error code. An E1 error
could be caused by a poor power source external to the monitor, or a fault could
exist within the monitor itself.
