3.3 Operating Procedure
The ETU-01A requires no operator attention once installed,
except for occasional monitoring of the front panel indicators.
Intervention is only required when:
• The ETU-01A has to be adapted to new operational
requirements.
• Diagnostic loops are required.
The ETU-01A is turned on when its AC power cord is
connected to an AC power outlet and the power switch is turned
to the ON position. The ETU-01A will perform its internal POST
(power on self test) to verify CPU, RAM, ROM and FPGA
integrity. The initial display looks like this:
