9. TIMER
The external timer of SC2128A may be bonding optioned into
six (6) configurations as shown. Each pressing of TIMER key will
step the internal timer one step up. The actual sequence
depends on the TIMER option selected. The following diagrams
show the timer sequence for each TIMER option. TIMER
automatically counts down as time passes by. The count down
sequence reverses the key sequence and is also shown in the
following diagrams.

10. RHYTHM WIND
SC2128A features rhythm wind mode. It can be set into
rhythm wind mode by pressing MODE key. Furthermore,
there are three levels – strong, middle and low rhythm
wind. Pressing SPEED key cycles SC2128A around the
three levels, from low to middle, middle to strong, then
strong to low. Initial rhythm wind level on entering
RHYTHM wind mode is the same as the ordinary wind
level while leaving ORDINARY wind mode and entering
RHYTHM wind mode. The right diagram depicts the
strong, middle and low rhythm wind patterns.
