procedures. Installation procedures (in Chapter 2) must be completed and checked before

attempting to operate the ETU-01A.

select parameter settings.

3.3 Operating Procedure

3.3.1 LCD and Menu Keys

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:
