locked) press E
NTER.  Once the parameter is flashing, use the UP and DOWN 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 instanta-
neously 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 HOME has the 
effect of pressing E
SC then HOME, 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 adjusting a parameter, the U
P/
D
OWN button must be held down briefly before the repeat rate increases.
