6.11.2.2 Numeric Parameters
Numeric parameters are displayed in reverse video. To increment or decrement
a number:

Each numeric parameter has a preset range of numbers assigned to it – for example,
a preset range of 1 through 10. If you attempt to enter a number which either
exceeds 10 or falls below 1, the incorrect value will be rejected – the original value
for this parameter, if any, will be displayed.

Y/N parameters can only be enabled (Y) or disabled (N). To enable or disable

Some Y/N parameters have sub-menus. For these parameters, a double right
arrow (») appears next to the “Y” or “N”.

values for alpha parameters consist of a predetermined set of acceptable letters or
