Complete the following steps to change the ramp rate of SSP.

6. Press the SCROLL

button until SP.RAT is displayed.

7. Press UP

or DOWN

button until the desired ramp rate is indicated on the

display. The unit of ramp rate depends on the type of ramp unit RAMPU selected.

8. The new ramp rate is applied when the button is released and is indicated by a brief

flash of the display.

9. Press PAGE

button to return to HOME display.
