at a particular level, use the D
OWN
button. To scroll forward through menu
items at a particular level, use the U
P
button.
To adjust a parameter, first locate the parameter by scrolling to the appropri-
ate menu (with combinations of the U
P
/D
OWN
and E
NTER
buttons). The display
will show the parameter field and the parameter value. To change the param-
eter, the parameter must be flashing. To make the parameter flash (assuming
the front panel is not locked) press E
NTER
. Once the parameter is flashing, use
the U
P
and D
OWN
buttons to adjust the parameter value. The parameter is
instantly updated while it is being adjusted — you should hear changes as the
parameter is changing. RS-232 control strings are also sent via the RS-232
port so your remote control device is instantaneously updated as well. Press
E
NTER
to select and store the parameter value or press E
SC
to cancel the
selected value and return to the old value. Pressing H
OME
has the effect of
pressing E
SC
then H
OME
, so the selected value will be cancelled and the menu
will return to the top of the menu tree.
Parameters that toggle or select among a list of options will wrap around
when you reach the end, but parameters that adjust numeric values will not
wrap around once the maximum or minimum value is reached. While adjust-
ing a parameter, the U
P
/D
OWN
button must be held down briefly before the
repeat rate increases.
