Set the level to 5 levels of "Medium low" and "Low"
In consideration of the contents of the jet form, the strength is varied.
Even if the display of the weak level is the same "medium", the jet is different if the jet form is different
They differ in strength. Table 6 shows the state transitions at the dynamic level.
That's right. In Table 6, in the vertical direction, the operation stopped state and five levels

Press (69) or (108) and release to change
"Weak" (state number "2") and switch (69) or
Press and release (108) again to decrease the dynamic level
(State number “1”). In program blows A, B, and C,
Squirting bath because the level is pre-programmed
Turn the hot / weak side switch (68) (69) or (107) (108)
Even if you operate, you can not change the strength level
You. In Table 6, “ON” indicates the operating strength.
This indicates that the level display lamp is turned on. In addition, “ON / OFF” indicates that the level cannot be changed.
When the program blow A, B, or C is operating,
Indicates that the bell display lamp blinks. Also,
“-” Indicates no change, “•” indicates OFF state.
