The unit's mode (settings) cannot be changed during a
program mode spin.
The Marathon Series has an internal memory capable of
holding 99 sets of run parameters. Each set, or program, is
stored and can be recalled by selecting a program number
(from 1-99). Programs are retained in memory, even if the
power is turned off. When necessary, a program can be
modified for a particular run or changed permanently. You
cannot change the unit's program, rotor/radius, or timing
modes, during a spin.
Press PROGRAM to enter Program mode
Select a program number with the numeric key pad. The
current program parameters will appear on the display.
Modify the desired parameter, including speed/RCF, time,
and temperature (if a refrigerated unit), using the numeric
key pad or modify the ACCEL or BRAKE modes.
Additionally, a radius value may be stored explicitly in the
program. The program number will flash, indicating that
the program was changed and has not yet been saved.
Make the changes permanent by pressing the SAVE key.
The program number will stop flashing, and the new
program settings will be displayed. The program will
remain in memory until further changes are made.
Because the Marathon 3000(R) has a fully automatic rotor
recognition system, the very first rotor that is spun using a
particular program will be identified and have its identity
automatically stored in the program. If a radius value was
not explicitly set by the user, the default radius (or
maximum allowable radius) for that rotor will be stored
with the program as well. If the user attempts to run a rotor
other than the one whose identity is stored in the program,
a "CH HD" (check head) message will appear.
If the user wishes to clear the rotor and its radius from the
memory banks of the program, he or she need only press
the SAVE button. The very first rotor spun after SAVE is
pressed will have its identity stored in the program,
